Having the appropriate tools for the job is the first step to producing quality work. Regarding drills, they vary considerably in size, function, speed, and power. Therefore, before you set out to buy one, it is crucial to educate yourself about the various types and their uses to make an informed choice. The following are the most common types of drills and their uses.

Manual Drills (Best for Home Use)

Manual drills were the first type to be created. They convert the circular motion you create physically into amplified torque to allow you to drill holes into hard surfaces. Even though manual drills are not as popular as they once were—due to the physical effort they demand—they are valuable tools to have around the house in case of a power outage. They include:

1. Eggbeater Hand Drill

This gear-driven drill has a driving wheel, which spins when you rotate the handle. Once the wheel starts spinning, the drill moves with the chuck, causing the bit to rotate. This manual tool is adept at making smaller holes in wood and metals.


2. Breast Drills

Breast drills function like eggbeater hand drills; the only difference is that they come with a plate attached to their back. The plate allows you to apply more drilling pressure by pressing your chest against the drill. It makes the breast drill more powerful than eggbeater hand drills.


3. Brace Drill

The brace drill has a U-shaped spindle that allows you to generate more torque. It also features another spindle at the top, which allows you to grip and align the tool in the desired position. The brace drill is used for countersinking when working with wood.


4. Bow Drill

The bow drill, also known as a fire drill, can start fires without matches. It has a bow, hearth, spindle, and bearing block. It utilizes friction to create heat, which creates an ember in sawdust.


5. Crank Drill

The crank drill features a high helix angle that allows it to create deep holes in tough materials by increasing its penetration efficiency. It also comes with a sharp tip to enhance its cutting ability. The crank drill is one of the few manual drills to drill into hard metals, such as steel.


6. Gimlet

A gimlet is a long drill bit that comes with a rotation handle. This tool utilizes leverage to create deep and broad holes. Extending its handles allows you to generate more force.


7. Push Drill

The push drill is a smaller but more powerful version of the hand drill. It features a spiral ratchet for rotating the bit. This drill is used in woodworking applications requiring a higher degree of precision.


8. Post Drill

The post drill is mounted on a durable post. These hand-powered presses can bore holes into iron, but the size and depth of the hole will depend on the operator’s strength.


9. Table Drill

Powered Drills

Powered drills are much more powerful than manual drills but less labor-intensive. As a result, they are ideal for DIYers and professionals. They include:


10. Cordless Drills

Cordless drills are battery-powered, which makes them incredibly convenient since you can use them anywhere. Cordless drills tend to have the least power out of all the powered drill types, but the powerful models are pretty expensive. Another disadvantage of cordless drills is their limited runtime. They are ideal for casual home users or professionals who have to work in off-grid job sites.

Impact drills are well suited for heavy-duty use in woodworking. Unlike standard drills, impact drills start pounding the material once they encounter resistance, thus allowing them to make holes in tougher materials. Nevertheless, they are unsuitable for fastening screws since they jam fasteners into the surface.


14. Hammer Drills

The hammer drill gets its name from its working mechanism, which involves a constant pounding motion. Like impact drills, hammer drills are also terrible at fastening. However, they are excellent at making holes in extra-hard surfaces.


15. Rotary Hammer Drill

This drill is typically used in masonry. It comes with an extra grip for better handling. The main difference between a rotary hammer and a regular hammer drill is that it uses pistons rather than cam plates to accelerate the drill bit.


16. D-Handle Drills

A D-handle drill is essentially a hammer drill with its trigger at the back instead of the front. D-handle drills feature powerful motors that generate constant speed and power. In addition to drilling, they are also used in mixing applications.


17. Combination Drill

WORX WX176L Combi drill

Also known as a combi drill, the combination drill can function as an impact and hammer drill. As a result, it is an excellent value for someone who needs both. Combination drills also work on soft and tough materials.


18. Mechanic Drill

A mechanic drill has a versatile design that allows it to adapt to light and heavy-duty use. Therefore, a single mechanic drill should do the trick instead of buying separate drills for softwood and metals.


19. Auger Drill

The auger drill is used to bore holes into the ground. It comes in both one- and two-person versions. The motor is positioned above the bit and comes with large handles.


20. Core Drill

30. Mini Drill

The mini drill is a type of hand drill that resembles a precision screwdriver. It is typically used for high-precision hobbies such as watch repairs and jewelry making. Despite the intricate nature of the work they are involved in, they are remarkably easy to use.

Conclusion

Although we’ve examined 30 types of drills, you’re unlikely to use them all. Electric drills and drill presses have generally replaced hand drills, but some crafters still use them for precise work. Most homeowners and casual DIYers benefit from having a cordless or corded drill for minor repairs and small projects.

However, purchasing a drill press is best if you frequently drill holes into various metals and hardwood. An impact or hammer drill is ideal for specialized projects and auto work.
