Smaller and cheaper drills often only have 10mm chucks, which might be enough if you're looking at nothing more than drilling in some small holes to hang pictures. You also want a keyless chuck, so you can loosen and tighten it by hand without having to worry about finding the chuck key. Pretty much all drills have keyless chucks these days. Essential for removing screws from timber or other material. The rotation button or switch should be reachable with your thumb or forefinger without changing your grip.
This should be easy to operate and give good variable control, from barely rotating to full speed. Good control at low speed is particularly important when trying to start a screw, or drilling on surfaces that don't provide good adhesion or friction, such as tiles and metal.
A range of gears will help you get the best results for different tasks. Low gear is for slow, powerful drilling, such as with a wide-diameter bit, drilling through steel or driving screws. High gear is for fast drilling, such as with small-diameter bits. This stops you overdriving or snapping a screw.
In CR's cordless drill tests, the top six heavy-duty models all feature brushless motors, as does the top-performing general-use drill—the only volt drill with a brushless motor we tested. Warranties indicate manufacturers' confidence in brushless technology: three to five years on the new tool vs.
We think that makes brushless a smarter buy. Almost all cordless drills come with a built-in LED work light, a single Phillips bit, and extras such as belt clips and hard-sided cases. A few brands stand out for extra features. Milwaukee offers chargers capable of charging its and volt batteries at the same time—nice if you own a drill of each type. How well your cordless drill performs can make or break some home improvement projects. Consumer Reports pits two big names against each other in a drilling face-off.

Cordless Drills Impact Drivers. Power Up With the Top Cordless Drills We test, evaluate, and compare the latest cordless drill models, so you can get the most for your money. See below for advice on how to choose the best drill for you. Features That Matter Here are five cordless drill features that are important to consider. Charger and Charge Indicator Early Li-ion batteries often needed to be charged and used under precise conditions to ensure peak performance.
Lithium-Ion Batteries Li-ion batteries for cordless power tools have two important specs. Brushless Motor Brushless motors reduce friction and sense resistance from the work material, continually adjusting the amount of power they draw from the battery.
Useful Extra Features Almost all cordless drills come with a built-in LED work light, a single Phillips bit, and extras such as belt clips and hard-sided cases. Bosch cordless drills are geared toward the contractor market and are available in multiple sizes, weights, and voltages. Bosch also makes and sells drills under the Skil brand.
Craftsman cordless drills are geared toward the consumer market and are available in multiple sizes, weights, and voltages. Craftsman drills are sold at Kmart and Sears and online at sears. DeWalt is one of the top manufacturers and marketers of cordless drills. DeWalt cordless drills are geared toward the contractor market and are available in multiple sizes, weights, and voltages. Hitachi cordless drills are geared toward the contractor market and are available in multiple sizes, weights, and voltages.
Kobalt is primarily a house brand sold at Lowe's, made by manufacturer Chevron not the oil company. Kobalt cordless drills can be found on Amazon as well. A hammer drill is perfect for those more heavy-duty jobs around the home, from putting up shelves to securing gutters in place.
Multiple torque settings allow you to adjust the power while keeping the RPM low, so it can power through hard materials whilst limiting damage to the surface area. Hammer drills do not always have a reverse screwdriving function, but impact drills do.
SDS drills have the same features as hammer drills, but the hammer action is improved with an SDS function commonly referred to as the Slotted Drive System. A piston firing the drill bit forward and pulling it back drives the hammer action on these drills.
This reduces friction and increases strength, allowing SDS drills to punch through the toughest materials with ease. Special SDS drill bits are used to eliminate the bit slipping and also to withstand the powerful force of its hammer action. These drills make light work of chiseling and chasing jobs.
Designed to handle breaking up hard materials like concrete, asphalt, bricks and blocks. Breakers and demolition drills deliver more powerful blows to the surface and can also be used to chisel channels in masonry and remove tiles. Depth stop: Fitted to the side of the drill, a depth stop can be adjusted to ensure that the hole being drilled does not exceed the desired depth. This feature can also give you a consistent depth when making multiple holes.
Trigger-activated LED: A handy feature to have, especially in dark conditions, is a trigger-activated LED light that automatically lights up when the speed trigger is pulled. The light will automatically switch off a few seconds after the trigger is released. Auxiliary handle: An auxiliary handle improves both safety and accuracy when drilling. The extra handle can be positioned on either the left or right side of the drill and helps to increase the users force and control compared to just using the pistol grip handle.
When selecting your drill, the drill's grip should feel comfortable to hold with an ergonomic design. Forward and reverse function: Drill drivers have a reverse function, which allows you to turn the drill bit or screwdriver bit forwards, as well as backwards. Reverse mode is also convenient when backing out the drill bit after boring holes. Keyless chuck: The chuck is at the front of the drill and holds the drill bit or screw bit. A keyless chuck means you can change bits quickly and easily, without the need for additional tools.
If too much torque is chosen, the screw can be driven too deeply. The excess power can also cause a loss of control and accuracy, causing damage to the work surface. Gears: Drills with more than one gear let you select different speed ranges. If the drill is a single gear drill, you can control the speed with the speed control trigger.
The gear control switch is usually located on the top of the drill. Integrated belt clip: Free your hands quickly and easily with an integrated belt clip, attached to the drill. Speed: Measured in revolutions per minute RPM. This number is shown as the maximum speed when the drill is not loaded and drilling. Some drills allow you to change the speed of the tool aka variable speed and, as with torque, you should do this depending on the material or task you are doing.
A low speed is ideal for driving screws or drilling into softer materials like wood, whereas a higher speed is better for drilling into harder materials like stone.
