What is the leading cause of dulling cutting tools?
Excessive heat is the leading cause of cutting edge deterioration. This can occur from cutting very abrasive materials such as MDF, melamine, plywood, etc. In addition, cutting tools become overheated and dull from improper and infrequent sharpenings, incorrect feed-rates and RPM, excessive removal of material, inappropriate cutting tool selection for the type of material and machine, and inadequate horsepower.
