How do they sharpen carbide tip blades? Do they have a machine, or is some guy with a huge visor and a leather shop apron sit on a stool with some specialized vise sharpening each little bevel with a tiny file?

If I go by what they charge me I would say it’s the guy with the visor.

It is not the machine that changes from HSS, Co or carbide, it is the grinding abrasive. for carbide Silicon carbide (green wheels) CBN or Dimonds are required. Norton has CBN available in a rectangular stick for use dressing Aluminum oxide , or silicon carbide wheels. Brazing carbide blanks onto tool blanks (lathe tools or sawblades) producees hazardous gasses that require special handiling to protect the workers and the atmophere and is highly regulated by EPA. ...... HOPE THIS EXPLANES WHY IT IS SO EXPENSIVE. By the way carbide is also expensive compared to HSS OR COBALT STEEL.

Have your say...
