1. The material of the drill is different. The center of the head of the electric hammer bit is inlaid with a piece of hard alloy, and the whole body of the electric drill bit is made of high-speed steel, so everyone must distinguish clearly.
2. Different shapes. Electric drill bits are generally of equal diameter, and the diameter of the carbide outer edge of the electric drill bit head is slightly larger than the diameter of the drill body. There are various shapes due to the different connection forms with the electric hammer , such as square, triangle, spiral, etc .
3. Different cutting edge. The cutting edge of the electric drill is used for metal cutting. It has a certain angle and slope, and the cutting edge is sharp. The electric hammer drill has no cutting edge, and the two sides are only chamfered. In addition, if the electric hammer bit is ground into the form of an electric drill bit, the electric drill can also be used to drill holes on the wall.
