According to the structure classification can be divided into

The head, body and shank of the integrated bit are made of the same material.

The top of the end welded bit is welded by carbide.

Incompatible by diamond classification can be divided

Straight shank drill The drill bit diameter is less than Φ13.0mm, all use straight shank.

The shank of the drill bit is tapered, and generally its taper is Morse taper.

According to the use of classification can be divided into

The center drill bit is generally used to hit the center point before drilling, and the front cone has 60°, 75°, 90°, etc. In order to use the tail seat support during lathe operation, the 60° center drill should be used to match the 60° top center of the lathe tail seat.

Twist drill is the most widely used drill in industrial manufacturing, and we generally use twist drill.

The end or all of the superhard bit before drilling is made of superhard alloy tool material, which is used in the drilling process of machining materials.

There are two small holes in the drilling body of the oil hole drill, through which the cutting agent reaches the cutting edge part to take away heat and chips, and the general working object of the drill is rotated while the drill is stationary.

Deep hole drill was first used for drilling of gun barrel and stone tube, also known as gun barrel drill. A deep hole drill is a straight groove in which more than a quarter of a round tube is cut to produce a cutting edge chip removal.

Bit reamer In order to mass production needs, the front end is the bit, the back end is the reamer, the diameter of the bit and the diameter of the reamer is only different from the reaming allowance, and the bit is also used in the screw tapping mixture, so it is also called the hybrid bit.

Taper bit A taper bit can be used when machining a die feed.

Cylindrical hole bit we call it countersunk head milling cutter, this kind of bit front end has a small diameter part called the rod.

Conical hole drill for drilling conical hole, its front Angle of 90°, 60° and so on, we use the chamfer knife is a conical hole drill.

A drill bit used in an electric drill with a handle shaped into a triangular face so that the chuck holds the bit in place.
