In general, the application of carbide drill bits in CNC machining has been very extensive, but the cost of materials is high, the correct use of carbide bits, to make the best use of them, is the responsibility of each machining practitioner, the reasonable use of carbide drill bits can improve product quality and save costs. The correct use of carbide drill bits mainly includes the following aspects:

1, choose the correct CNC drill can be applied to CNC machine tools, machining centers and other powerful, rigid machine tools, and should ensure that the tip of the TIR<0.02. However, radial drilling, universal milling and other machine tools are easy to lead to early collapse of the drill bit due to low power and poor spindle accuracy, which should be avoided as far as possible.

2, choose the right tool handle spring chuck, side pressure tool handle, hydraulic tool handle, hot expansion tool handle, etc., can be used, but because the quick change drill chuck clamping force is not enough easily lead to the drill bit slip and failure, should be eliminated.

3, carbide drill bit correct cooling

(1) The external cooling should pay attention to the combination of cooling directions, form an upper and lower echelon configuration, and reduce the Angle with the tool as much as possible.

(2) The internal cold drill should pay attention to the pressure and flow rate, and should prevent the leakage of coolant affecting the cooling effect.
