Introduction to some common electric drill typetypes

Apr 20, 2023

What is a drill bit? What are common electric drills?

A drill is used to drill round holes in wood materials or drive fasteners such as screws. The most common types of drills accomplish this task by rotating an equipped drill or driver bit at high speed when the user pulls the trigger. These tools can be manual, corded, battery-operated, or pneumatic, and they are widely used in many professional industries. Carpenters, electricians, auto mechanics, and even plumbers often have power drills on hand or in their work vehicles because of the versatility of these power tools.

Most DIY enthusiasts have at least one drill at home for various tasks, such as hanging TVs or wiring. You can find complete drills specifically designed to drill round holes in or into different materials, but combination drills/drivers may be more beneficial to the DIY hobbyist. These combination tools can be used as standard drill bits or with different settings when you use fasteners. Check out this guide to learn more about these common types of drills.

1. Electric drills

Best used for: tightening fasteners and drilling holes in wood, plastic and thin metal.

Drill drivers are the most common type of drill for DIY enthusiasts because they are designed with a standard drill function and a driver function to tighten or loosen fasteners. The standard drill setting allows the drill to spin at high speeds to drill holes in wood, metal, and other materials, while the driver setting reduces the spin speed and increases torque to drive fasteners, such as screws and bolts.

These drills are available in corded electric, battery-powered, or pneumatic models so that you can choose the right drill for your needs. If you only have one type of drill at home, it is recommended that you use an electric drill because the tool can be used for DIY repairs and renovations.

2. Hammer Drill

Best used for: applying an impact force to drill through masonry materials.

Hammer drills combine rotational and impact forces to drill through various masonry materials. Standard drills do not have enough rotational force to drill through hard materials such as brick and mortar, so hammer drills also have a hammering mechanism that repeatedly drives the head of the drill against the target material while the drill is spinning rapidly.

Many impact drills can also be set to standard drill or drive modes, allowing you to use them for various tasks. However, it is important to mention that you will need a drill bit if you use a hammer to drill through masonry material. A standard wood drill bit will shatter and possibly break from the impact.

3. Electric Hammer Drill

Best used for: Heavy-duty drilling in brick, concrete, or even rock.

An upgraded version of the hammer drill is the rotary hammer drill, which combines the rotary power of a hammer drill with extreme impact, similar to a small handheld drill. These drills can be used for various jobs, such as laying water lines in the foundation of a new home. The average DIYer won't get much use out of a hammer drill, although they are common in many industries.

If you need a hammer drill for a project at home, it is recommended that you rent one from your local home improvement or tool rental station rather than spend money on this specialized equipment.

4. Impact driver

Best used for: driving fasteners in tight spaces.

An impact driver is a compact tool for driving screws and other fasteners. The handle and trigger are essentially the same as an electric drill. Still, the body is shorter, allowing the impact driver to access areas that a typical electric drill may not be able to reach.

These typically battery-powered tools prioritize torque over speed, making them ideal for driving or removing long, thick screws and bolts. They are also available in pneumatic and corded versions. Impact drivers are of limited use for drilling. It is best to rely on a standard drill or drill driver for most situations where drilling is required.

5. Ground Drill

Best used for: drilling holes in the ground.

Ground augers are used to dig holes in the dirt, allowing you to install fence posts or till the soil for vegetables, flowers, or other vegetation. These tools are also called back holes, earth, or soil augers. While you can purchase an auger for your home, if you only use an auger occasionally to install or replace fence posts, it's usually not worth making the expensive investment. Instead, renting an auger for a short period is advisable to complete your project and save some money.

6. Right angle auger

Best used for: drilling or driving in very tight spaces.

Right-angle drills have a long, narrow handle that extends to a small, vertical head that holds the drill. Right-angle drills are a good choice if you work in tight places, such as under a sink or above a ceiling. These tools are made to be easy and mobile, so batteries usually power them.

Use a right-angle drill driver to drive fasteners when there isn't enough room for an impact driver, or you can use this tool to drill small holes in wood or thin metal. However, right-angle drills are not designed for power, so if you are short of tools, you may need to switch to a more powerful drill to get the job done.

7. Electric driver

Best used for: tightening or loosening screws and other fasteners.

Electric screwdrivers fall into the drill category due to the powered rotational force used to drive the screw. These portable tools usually have a built-in battery that needs to be charged before the screwdriver can be used. Once charged, the screwdriver tip will rotate to drive screws and other suitable fasteners, depending on the drill bit.

You can use an electric screwdriver instead of a regular screwdriver to save time and effort. They are also great for working in tight spaces that are difficult to access with a standard electric drill or impact driver, such as inside a ceiling or behind a wall.

How to choose a drill?

There are a variety of drills to choose from, each with its advantages to help users accomplish specific tasks. With this in mind, you need to clearly understand how you want to use the drill before choosing the right drill for your next project. If you need precise drilling, a drill press is a good choice, but if the material is too large to fit on the drill press table, you may need to rely on a handheld drill or drill press to get the job done.

Some drills, such as a floor drill, are so specialized that you may not need to own them. Simply rent the tool from your local home improvement store to excavate any fence posts you need, then return the tool when you're done. Also, remember that you'll need to choose between a corded, battery-powered, or wind auger. A manual auger is also an option, but in most cases, a power auger is a right choice. Pneumatic drills are typically used in industrial and commercial shops, but if you have multiple pneumatic tools, investing in a pneumatic system for your home shop may be worth it.
