Cemented Carbide Twist Drill Grinding

Results: HSS drill processing, processed out of the aperture size tolerance, reached after the switch to cemented carbide twist drills prefabricated hole reamer machining requirements.

Summary: during the processing of this material, if not cemented carbide twist drills chisel edge processing to a certain extent, the life of the cemented carbide twist drills will be halved, it is necessary to mechanical cemented carbide twist drills type grinding.
