The cutting edges of a tap become dull during cutting at a rate dependent on cutting conditions and the material being cut With increased wear the cutting torque increases and breakage will occur if sharpening is not carried out in time
Increased wear of the cutting edge is also indicated by poor chip formation.
In addition, the surface finish of the thread flanks is poor and burr formation is perceptible.
