The whole alloy drill often breaks
1, choose machinery with better mechanical performance to minimize the unevenness of bit feed.2, fixed firmly machined workpiece, minimize and avoid workpiece vibration, workpiece beating phenomenon.3, the processing of the feed should be stable, slow, slow, remember to act too hastily.4, if all aspects of the existence of factors, can not guarantee smooth drilling, you may wish to use carbide inserts bit. The body of this drill is made of tool steel, except that the cutting parts are inlaid with carbide inserts. The drill bit does not hurt even if there is a certain amount of vibration when drilling. It will not cause the bit to break.
Alloy drills often break because: because of the overall alloy bit, although the material is very hard, but relatively speaking, brittleness is also big. In the drilling of carbide bit, the drilling of the bit is unstable, the vibration of the workpiece and the beating of the workpiece will cause the fracture of the whole alloy bit.
Drilling with carbide drills is the most afraid of bit feed instability, vibration and pulsation, which is the most likely to break the drill bit. If the drilling is not guaranteed, the cemented carbide bit can be used instead. The body of this drill is made of tool steel material, but only hard alloy material is inserted in the cutting part. The drill will not break the drill even when it is drilling.
