1. Choose the right machine:

External cold carbide drill bit used in CNC machine tool processing, the choice of the machine is the choice of power, steel is good, and should ensure that the nose beating TIR <0.02. The rocker drill, universal milling and other smaller power, poor spindle accuracy of the machine, easy to lead to early collapse of the carbide drill bit, should be avoided.

2. Correct drilling process:

(1) 2-edge drills shall not be reamed.

(2) When the drill surface inclination> 8-10 degrees, not drill. <8-10 degrees, the feed should be reduced to normal 1 / 2-1 / 3;

(3) When the drilling surface inclination> 5 degrees, the feed should be reduced to normal 1 / 2-1 / 3;

(4) When drilling cross hole, the feed should be reduced to normal 1 / 2-1 / 3;

3. Correct cooling:

The outer chilled carbide bit should be noted in the direction of the cooling combination, forming the upper and lower echelon configuration, and minimizing the angle with the tool.
