There are many types of drill bits on the market, and there are many types of drills that can only drill wood. Either they cannot be drilled or the drill is inaccurate, or the drilled hole is not big enough. As a woodworking drill manufacturer, I would like to share with you several common drill bits for wood and how to choose the right drill according to your own situation.

①Twist drill bit

Because of its high hardness, twist drills can also be used to drill metals. If you need to drill holes in metal materials,  it is best to choose a slightly higher price metal twist drill, which will work better.

②Countersink drill bit

It is used to drill countersunk holes in order to screw in countersunk screws later.

Pointed in the middle. The incision is rough, the drilling accuracy is poor, and the efficiency is relatively low. But the price is cheap. If the quality of the board is relatively light, this kind of flat drill is most suitable.                            

④Hole saw

It is used to make larger holes and is suitable for thinner materials. Because there is a drill in the middle called a centering drill, the drilling accuracy is high and easy to use, but it is limited by the thickness.

⑤Auger bit 

The drilling is more precise with a hollow spiral structure. Strong chip removal ability, high efficiency, and fast speed. It is suitable for drilling a large number of holes.

The center is pointed, so it is easier to locate. Especially when you need to do some high-precision carpentry work, you need to use a three-point drill. And the price is relatively cheap and cost-effective.

⑦Forstner bit

You need to use a flat bottom drill to drill when you don't need to drill through the wood, but just want to drill a hole in the wood.

⑧Auger Bits

On the one hand, it can be used to drill wooden blocks, and the drilled holes are relatively neat. The drilling speed is also relatively fast, so the work efficiency is relatively high. If you need to drill deep holes, it is also more suitable. On the other hand, it can be used to draw circles.
