What are the different drill types?

The two primary types of cordless drills are the drill/driver and the hammer drill.

• Drill/drivers are useful for making holes and driving screws into wood, metal, or plastic, making them the most common type.
• Hammer drills also serve the same purpose but include a hammer function to aid drilling into harder materials such as brick or concrete. They are typically heavier than standard drill/drivers.

You might also encounter rotary hammers, which are heavier-duty tools primarily for professional use, and impact drivers, specialized in driving screws and loosening bolts.

It's common for users to have both types for various tasks, and many manufacturers offer combo kits that include a drill/driver with an impact driver or hammer drill.

What is the chuck size and drill bit?

The chuck is the component of the drill where drill bits are inserted. Drill bits, which are available in various sizes, must be exchanged based on the task. The chuck size determines which bits can be accommodated. Most drills feature a maximum chuck size of 13mm, which suffices for general repairs, while some smaller models have 10mm chucks ideal for light tasks like hanging pictures.

The typical minimum chuck size ranges from 1 to 2 mm. You'll rarely need bits smaller than 1 mm for everyday projects. Newer models usually feature a keyless chuck for ease of use.

Using the right bit for the job

The manual often includes a guide for selecting the appropriate drill bit size for different materials. It's beneficial to consult an expert at a local hardware store to ensure you're picking the right bit for your drill's chuck size.

Torque and drill speeds explained

Torque measures the force the drill exerts to rotate the bit, which varies based on the material in question. Adjustable torque settings are essential, along with multi-speed gearboxes (measured in RPM), allowing you to control both torque and speed effectively.

Utilizing maximum torque at all times may lead to overdriving screws or damaging materials. Harder materials generally necessitate higher torque and lower speeds.

As a general rule: harder materials require more torque and less speed

Torque adjustments can usually be made by rotating the selector near the chuck, and various settings will prevent overdriving or damaging the screw.

Buying the best drill battery

Most cordless drills use Lithium-ion (Li-ion) batteries, where capacity is indicated in ampere-hours (Ah). Generally, higher Ah translates to longer runtime. The charge rate is also significant; quicker recharge times keep projects on track.

Battery voltage (measured in volts) is indicative of power. While higher voltage usually means better torque, real-world performance can hinge on factors beyond voltage alone.

Do you need a second battery?

Having a spare battery can save you from delays when the primary one dies. Many tool kits offer savings by bundling two batteries together instead of purchasing them separately.

Can the battery power other tools?

Most cordless drills from major retailers utilize batteries that are compatible with other tools from the same brand, like Ryobi or Bosch. This compatibility allows for greater cost efficiency and reduces storage needs.

Other features to look for

Belt clip: Handy for hands-free storage while working at height, especially on ladders.

Brushless motor: Provides better energy efficiency and quieter operation while offering enhanced torque and speed control.

Carry case: Hard cases offer protection but can be bulkier; soft cases are lighter and easier to transport.

Charging cradle: Allows simultaneous use of one battery while charging another, improving productivity.

Charge level display: Helps you keep tabs on battery life.

Light: An onboard light can be invaluable in dim workspaces.

Reversible direction: Essential for unscrewing and easily accessible via thumb or forefinger.
