Carbide center drill is a type of carbide drill bit. It is mainly used for processing center holes on the end faces of rotating parts such as shafts. It can also be used for prefabricated precise positioning before hole processing to guide twist drills for hole processing to reduce the cost of drilling. error. It is an alloy material, mainly formed by powder metallurgy, with fast cutting, good chip removal, wear resistance and long service life.
According to the processing requirements, center drills are divided into two types: without cone guard and with cone guard. Center drills without guard cones are mainly used to process center holes with a diameter of d=2-10mm, while center drills with guard cones are mainly used for workpieces with long processes and high precision requirements to avoid the 60-degree centering cone from being damaged. damage.
