How to solve the problem after the bit is broken?

 

 

Cause Solution
Bending, deformation, sliding Increase the rigidity of tool and machine tool, increase the rigidity of workpiece and jig
Lip Relief Angle is too small Regrinding Lip Relief Angle
High Stock Removal To reduce Stock Removal
Bit wear Use drill bit grinder to grinding
Blocking of chips Re-select the alloy bit (chip groove, helix Angle);

Re-select machining method (adjustment of feed rate, step-step method, etc.)

Poor cutting Increase the rigidity of tools and machine tools

Increase the rigidity of workpiece and jig

Predrilling center hole

The cutting plane is first adjusted or processed into a horizontal plane with a guide sleeve
