Drill Definition/ Drill Meaning

A drill is a tool that you can use for boring holes or fastening materials together. It has a cutting tool attachment or instead of it a driving tool attachment. At one end of the drill, there is a chuck; it rotates when you press it against the target material.

The tip of this tool does cutting into the material. In woodworking, metalworking, or construction, people frequently use this tool. Some particular types used in medicine and space missions.

These have power and capacity characteristics. Over the last century, multiple sizes and types of drilling machines have been invented.

List of Different Types of Drills and Their Uses

To work with drills, you should know about their types and uses. Here is a list of drills and their uses:

#1. Hand drill/eggbeater drill:

Hand drill photo

First to know about hand drill is, it’s a manual tool, it is gear driven. This tool has a driving wheel. You can spin it by using the turning handle.

When the wheel spins, the drill moves with the chuck. And it causes the bit to rotate. Who doesn’t want to use a power drill can choose the hand drill. Many woodworkers use this tool.

One can use this hand tool for drilling small holes. Sometimes it is difficult to make a small hole with other drills, but you can do it using a decent hand drill. A hand drill can quickly create a small hole in softwood and soft metals.

#2. Brace drill:

brace drill

Another manual drill is the brace drill. It has a U-shaped spindle which is cranked to lend more torque. That has another spindle on the top for gripping and fixing it in the desired position.

When working with it, hold one spindle with one hand and use another hand to rotate the second spindle in the clockwise direction. Therefore, you can make a precise hole using this tool.

The use of the tool is in countersinking in the wood. You can also pierce wood utilizing the device. Other tools may not work in this case, but a quality brace drill is useful.

Our Recommended Brace Drill:

#3. Bow drill:

bow drill

Another name of the bow drill is a fire drill. There has a bearing block, a spindle, a hearth, and a bow. It is a way of starting a fire without matches. By applying friction, generates heat. The heat produces ember in the sawdust.

Tinder bundle forms by the amber, and it bursts into the flame. One end of the spindle reduces the friction to maximizes at the other end. The bearing block holds one end and the baseboard the other. The string helps to tight enough so that it does not slip.

The frequent use of it is to make friction fire. With the same principle, you can do woodworking and dentistry.

#4. Crank drill:

crank drill

A crank drill is a twist drill that can make deep holes into harder materials. It has a high helix angle that increases penetration efficiency. And it has a sharpened tip to improve the cutting ability of the drill machine.

You can quickly drill into hard materials like steel and metal alloys. Curve surface drilling is also possible with this tool. If you centered it once, it wouldn’t slip, it has the accuracy.

#5. Gimlet:

gimlet tool

A gimlet is the larger version of the auger. It is a long drill bit that has a pair of handles for rotating it. And it looks like a corkscrew. The principle of a gimlet is based on leverage.

If the handle is more extended, you can apply more significant force. You can also use it as an auger and reamers. Some are so huge that anyone can’t operate the tool. So you need a lot of experience to run it.

To drill a broad and deep hole in the wood where you can’t get a great result using a bow or pump drill, use a gimlet. You can also use this to bore water pipes.

#6. Breast drill:

breast drill

Breast drills are about 15 inches long and have a concave plate. The plate gives the user support to lean when boring a hole. The other names of breast drills are – chest drills, belly drills, knee drills.
