Cordless drill Leaderboard 2021
WHAT IS A CORDLESS DRILL?
This is an electric drill which uses rechargeable batteries. It has similar features to the Ac main- powered drill and is available in the hammer drill configuration. Moreover, most have a clutch, which aids in driving the screws into various sub striates while not damaging them.
One of the most common tools and we’re sure you have seen in a hardware store or in that toolbox is the Drill. You might ask yourself what you can do with a drill. First of all, you should understand that the drill is the most crucial part of finishing the handy work.
HOW DOES A CORDLESS DRILL WORK
A Cordless drill works when you depress the trigger on the front of the handle. The result is the cluck spines at speed proportional to the degree to which you depress the trigger. It is necessary for you to have decent hand strength and finger control to insert the bit as well as keep the cordless drill spinning out of your hand to use the cordless drill efficiently.
The purpose of the cordless drill is to turn ‘bits.’ Bits are the tools that go at the end of the drill, and they come in different shapes, to accommodate driving, drilling, mixing or cutting. For drilling, drill bits come in many sizes, from small fractions of an inch up to about an inch in diameter.
The materials of cordless drill bits vary as well, depending on the surface you’re drilling into. Also, proper use must be defined by the environment the cordless drill used in factoring in the best lighting, reasonable low ambient noise and a lack of excessive moisture getting into the casing.
To operate the cordless drill your battery should have sufficient charge, this involves sliding the battery off the cordless drill and onto the 12v charging device that plugs into the wall. After 2 hours the battery will be fully charged, and you will slide it onto the base of the drill. Once the battery is in place, the chuck’s teeth hold the top of the cordless drill steady and turn the collar on the end of the drill counter-clockwise.
Push the clutch into forwarding or reverse depending on the application, and place the bit on the desired surface. While bracing it firmly, gently squeeze the trigger while pushing forward till you find your desired speed. Once your task is complete, push the clutch back into the centre position and set the drill down.
ADVANTAGES AND APPLICATION OF CORDLESS DRILL
- They’re compact
Cordless screwdrivers tend to be relatively small which means they’re ideal for working in awkward or confined spaces.
- They’re relatively inexpensive
Prices start from around £20, making cordless screwdrivers one of the least expensive Cordless Drills.
- They’re lightweight
Cordless screwdrivers can weigh as little as 500g – That’s about the same as a 500ml bottle of water.
- You can change between bits quickly and easily
Most cordless screwdrivers have a magnetic or quick-release chuck which allows the user to switch between different bits rapidly.
APPLICATION/ USES OF THE CORDLESS DRILL
- Replacing the screwdriver
The cordless drill’s top use involves attaching and assembling. Using a screw bit, the craftsman can position a screw on the end of the bit and quickly insert it into the project. With the flip of a switch, the cordless drill driver can rotate counter-clockwise, making it invaluable for removing screws as well as installing them.
- Pilot holes
When you’re inserting screws into wood that may split, a cordless drill, with a bit one size smaller than the diameter of your screw, lets you drill a pilot hole before inserting the screw. It is also beneficial in finish carpentry where even a tiny split would detract from the quality of the item. This is because a screw digs into the wood and separates the grain, it tends to split the wood, especially if the screw is large. However, by drilling a pilot hole first, you can insert the screw and minimize wood splits.
- Hole’ saw
Your cordless drill doubles as a saw for cutting out holes for doorknobs, sink faucets, drains and other round holes. Hole saw-bits come in various sizes, and they attach to the cordless drill, allowing the tool to do all the work of cutting out a perfect circle.
- Drywall installation
Drywall installers carry their cordless drills on their tool belts for quick access. Installing drywall requires lifting and holding large panels in place before inserting drywall screws into the studs beneath the wall.
With one hand bracing the panel, the installer can grab cordless drill — fitted with a magnetic screw tip — and insert the screw through the drywall with ease.
The cordless hammer drill, a particular type of drill used to drive bolts into concrete, incorporates a slight vibration along with the strong rotating action of the cordless drill.
A cordless hammer drill is indispensable for bolting down outdoor furniture to concrete or for installing any screw into concrete.
TYPES OF CORDLESS DRILLS
Used for drilling holes and driving screws into timber, metals or plastic. The best and most common type of drill to use in handling light duty handy jobs.
They also do the same task as the driver drill but also have a hammer setting that rocks the drill bit in and out for drilling into masonry, i.e., brick, stone, and concrete. They tend to be a bit heavier than the drivers.
Essentially heavy-duty versions of the hammer drill and mostly used by professionals in the trade. It’s more potent than the hammer drill and also tends to be bigger, heavier and more expensive as a result.
Are explicitly designed for driving screws or loosening bolts. It can deliver huge torque and tends to have a smaller profile which makes it easier to fit into tight workspaces.
THE BIG CORDLESS DRILL BUYERS GUIDE
Before getting your hands in one of these machines, there are a couple of things you should know first in order to have the right drill for the right job.
With a drill comes responsibilities, you don’t want to buy a drill that you will find hard to handle so check out some of the common weakness that have been notes;
Big and bulky
The batteries are usually attached to the handle and can be quite large. Depending on the job that you are doing, this may not be the most convenient feature. With increased size comes more difficulty fitting into tight spaces. Therefore, in those situations, it is best to turn to a smaller corded drill or a screwdriver to finish the job.
The cordless drill becomes heavy due to the battery attached. Working the cordless drill can result in fatigue on your arms holding a massive, battery-powered drill up above your head for hours can wear you out faster than using a lighter corded drill or a screwdriver.
Waiting on power
When you deal with a rechargeable drill, you will always be faced with the issue of waiting for power. Even if you remember to plug your battery in every night, at some point, you will run out of power when you need it. On top of that, many people forget to plug the battery in when they finish and regularly do not have power when they need it.
As with many electric motor machines, the cordless drill is subject to overheating of its motors.
DIAGNOSING YOUR CORDLESS DRILL
There are some signs that will indicate that your drill is not in a good condition, some of these signs may be minor and others might be very major. Always be keen in looking for these kind of signs to know how to diagnose defective drills and how best you can handle them on your own.
- It won’t start?
If your cordless drill doesn’t start, it could hint at some lager electrical problems including a short or part malfunction. Best start by checking the power switch and its assembly to make sure there are no damages as heat and water damage can be the culprit of a drill that won’t start.
- Weakened Power
Your drill starts, but the power level is so weak that you’d probably be better with a corded drill. When your Cordless Drills lose their 00mph (and it’s not a low battery), the most likely cause is worn carbon brushes that best need replacement.
The carbon brushes are the small carbon blocks that transfer the electrical current from your power source to the tool’s motor itself. If your brushes are precise, there may be damage to your tools’ commutator or the rest of the build-up and even melted insulation are signs that these parts are the root cause.
- Burning Smell
Malfunction motors tend to give off a very recognized burning smell when something is wrong. Everything still spinning but the drill is no longer working, and it just stinks. Diagnosing this smell could change depending on the type and design of your Cordless Drill. It could also just be a case of the cordless drill overheating. Motors generate a lot of heat when in use. If the tool has been running too long or too hard, the machine can overheat and cause a burning smell. For the best cordless drill’s safety, immediately turn off and let it settle for about 30 minutes before attempting to diagnose the problem.
- High-Pitched Screeching Noise
Using a cordless drill can be pretty loud. However, sometimes a Cordless Drill starts making a high-pitched screeching noise, or screaming; that goes above and beyond the loud hum of your electric hammer drill. Make sure that your control is best lubricated if it makes such noise. Check the manufacturer’s specification for maintaining your drill to find out the best method to keep your tool lubed.
- Sparks and Smoke
If your drill begins to emit smoke or sparks, turn it off immediately. You should never continue using a Cordless Drill that is smocking or sparking. It is best advised to Set your tool aside and allow it to cool down before attempting to diagnose or fix the issue. Once the tool is cooled, check to see if any dust or debris has gotten into the machine. Sawdust or other particles that frequently fly through the air in heavy work areas can get into your tool’s vent and cause that sparking or smoking.
If your tool is free of burning debris, you may need to take apart the tool’s casing and check for heat damage.
REVIEWS AND CONSUMER TESTS REPORTS
Below are reviews done by various consumer groups regarding the performance of different type of cordless drills.
Consumer Report Review
According to a review by consumer report, most lithium-ion batteries found in cordless drills charge within an hour (30 – 90 mins), while nickel cadmium battery packs take 4 to 5 hours for a full charge.
Many of today’s cordless drills also largely reap benefit from a motor makeover. Brushless motors, not long ago were reserved only for illustrious brands such as DeWalt, Makita, and Milwaukee that were contractor oriented, but now they’re widely available and can be found on modestly priced consumer drills such as the likes of Porter Cable, kobalt and Ridgid.
Brubshed motors are susceptible to run flat-out irrespective of whether you’re drilling into softwood such as pine, or a hardwood, such as oak. Sometimes that is overkill, and it will drain the battery needlessly. Brushless motors, in contrast, operate with reduced friction. Allowing them work efficiently and spin faster. They adjust relative to the level of resistance they encounter and drain the battery more amicably than motors with brushes. They also feature fewer moving parts, and because they have no brushes in their making, you never need think about replacing them.
Nearly all top-performers in Consumer report’s up-to-date rankings feature brushless motors.
Reviewing the Limits
1. Power score: This forms the basis of the Power review score in Consumer Report’s ratings. The more power a drill has or it can assert the bigger the screw it can drive, as well as the bigger the hole it can bore before the motor cuts out.
2. Speed test score: This is calculated to reflect the time each drill being tested would take to perform a given task. Models with higher scores reflect drills that can drive screws, as well as drill holes faster than those with lower speed test scores.
3. Run time and Handling score: Run time in this test can be defined as a reflection of how long a battery can last on a single charge i.e. supposing you used it to perform the same task again and again. They also reviewed cordless drill qualities such as balance, the feel of the handle, and trigger pull to meritoriously assign each model a score for Handling.
4. Decibels test (Noise-at-ear score): Last, the team measured and reviewed decibels. An exercise designed to capture a Noise-at-ear score for each tool. As it turns out from the exercise, all but the smallest models require users to make use of hearing protection for safe use.
And if you run into a situation where a cordless drill just isn’t up to the task, you can always pursue renting a heavy-duty corded drill from a home centre. Better to explore such a solution than purchase 20th-century technology.
Which.co.uk Review Report
They tested and reviewed all drills for performance, to see how well they can drill into wood, stone and metal, how well can drive screws, and if they have a hammer action, how well it copes with concrete.
They reviewed the batteries by measuring how many holes they can drill on a full charge and after a quick 15-minute charge, as well as their stand-by consumption rate.
They tested and reviewed each drill’s endurance by running it on-and-off for 33 hours to simulate years of use and find out whether performance deteriorates. They also did an in-depth review of the electrical safety of each drill – this includes checking for protection against shock and experiment to see what would happen if you were to drill into a live electrical cable accidentally.
Major areas they looked at; on top of testing and reviewing drilling, hammer action, and screw driving, they also reviewed each drill for its battery life, charge time, and ease of use. A great Best Buy drill will do well across all the critical tests:
1. Drilling: They speed-tested each drill at various diameters in sandstone, wood, and metal, to test and review the range and breadth of tasks you could expect to use it for.
2. Screw driving: If a drill has adequate torque control, each screw should be inserted to just the right point, without over-tightening or sticking out, into wood and metal at a range of sizes.
3. Hammer action: The speed-test combination drills test/ review with hammer-action settings against one of the most robust materials you’ll be working with: concrete.
4. Battery: The best battery will be able to drill and screw hundreds of holes on a full charge. Some also perform well after a quick 15-minute top-up charge.
5. Ease of use: An expert panel rates how easy each drill is to use, and reviews how comfortable it feels.
6. Endurance: They start and stop each drill for 33 hours, to simulate years of occasional use. The best cordless drill should last until the end, without developing any faults.
Buying a Better Drill
When buying your next cordless drill, you’ll find that one of the paramount questions you’ll need to answer is what voltage drill you want. This is an indication of power. That said, though an 18 or 20 Volt cordless drill should deliver more torque than a 12 Volt model, it’s also relatively bulkier. Looking at the two reviews, it clearly shows that consumers are going for efficiency, power, affordability, and durability. What to consider:
Battery life score
Based on how many 10-12x25mm TEK screws can be screwed in and out of the 32mm thick MDF on one battery charge- the more screws, the higher the review score. For a drill that comes with two batteries, the most significant capacity reviewed as many people tend to use it first.
Based on screwing TEK screws of two different sizes (14G 50mm and 14G 75mm, 25 of each) into and out of MDF (96mm thick). The more screws screwed in (thoroughly flush with the wood), the higher the score.
A drill that manages to drive all the screws entirely in and outscores 100%.
Based on the time taken to drill ten holes with a 13mm spade bit through 45mm hardwood (spotted gum). The faster the time gets the best score review.
Ease of use
The drills are reviewed for weight and balance, and grip comfort, by a right-handed man, a left-handed man, and a right-handed woman.
The cordless drills are the best and far better than a traditional drill as it works silently. All the cordless drills are designed to provide high-quality performance at affordable rates. You will find many cordless drills in the market with different features, accessories, and warranty periods that might confuse you.

INTERESTING FACTS AND GUIDES
Development of the cordless drill over time
The first portable drill, assembled in 1916, is at the National Museum of American History in Washington, D.C. Electric drills were in operation long before 1916, but they were large, stationary machines used in industrial and manufacturing facilities.
In mid-1960s Martin Marietta Corporation contracted with Black & Decker to design tools for NASA. The tool company developed a zero impact wrench for the Gemini-project that spun bolts in zero gravity without spinning the astronaut. Black& Decker also designed a cordless rotary hammer drill for the Apollo moon program.
Milwaukee made the drill more durable and developed more powerful cordless drills including right angle drill and variations to the primary drill/driver in both corded and cordless versions.
The first cordless hammer drill came into the market in 1984 (Bosch).
Currently, there have been significant improvements done on battery life and accuracy. Engineers and field technicians, however, are bound the technical limitations of lithium-ion battery packs, which present a series of drawbacks.
Power drill gives off intense vibration, especially on high torque. They can also reach- high temperature because of the impact on friction. For safe handling of the tool, it is best you wear thick gloves at all times. Gloves are also best useful in preventing contact with the hot surface as you change drill bits or loosen the chuck.
When operating a power drill, tiny materials from the target surface may fly off into the surrounding space. If such a particle enters your eye, it may be tough to remove, in addition to causing pain and discomfort. Your best protection is to wear sturdy safety goggles that will protect your eyes.
Wear a thick jacket to protect yourself while working with a power drill. Best avoid long clothing that can get entangled in the work surface. It is also best to avoid jewellery and keep long hair restrained and out of the way.
Best turn off the switch and unplug the power cord. Never change drill bits when the power cord is still connected to the power supply. If you accidentally press the power button, you could be seriously injured. Thus it is best to make a point of using the safety latch when the drill is not in use, and most power drills have this safety-enhancing feature.
Best ensure that Chuck is Tight before Using the Drill:
The chuck is the restraining mechanism that holds the drill in place. A power drill can have a keyed or keyless chuck. A keyed chuck needs a particular key to turn the chuck and tighten it in place, whereas a key-less chuck can be tightened merely by hand.
When you complete a drilling job, you must unplug the drill, loosen the chuck and remove the drill bit before you can fit in a new drill bit or tip. A loose chuck is hazardous because it will not hold the drill bit in place. If the drill bit comes undone and flies off in the middle of a job. This is best observed because it can cause significant danger to surrounding people.
Ensure that you use the correct drill bit. Using the wrong bit will lead to a lousy job and will also require the use of a lot of force. It can also damage the power drill over time, therefore it’s best advised to use the correct drill bit for every job.
If the best cordless drill has reversing torque feature, it can ease the removal process.
CARE AND MAINTENANCE
Taking proper care of your cordless drill can ensure that your drill stays in the best condition for years to come. Every Cordless Drill is an investment, and it is always the best idea to take care of your finances.
Below are some basic tips for proper cordless drill care:
