1. Carbide bit grinding is generally behind grinding. The latter has less impact on service life. 2. The workpiece material with high strength is easy to cause wear in front of the drill (spiral groove), which has a great influence on the life of the drill. 3. Edge wear of bit has the most serious impact on bit life. 4. Therefore, when using the Drill Bit, pay attention to: (1) When clamping the bit, the diameter jump of the top of the bit should be as small as possible. (2) The machine Tool spindle has enough rigidity and accuracy. (3) The drill should be replaced and grinded when it is used properly. 5. Drill bit can be recoated after grinding, and pretreatment should be done before coating. To increase the coating effect.
