How do I know a cutter has dulled?

Burn marks, fuzzing on the surface and rising feed force. Sharpen or replace at that point rather than forcing it.

Can cutters be resharpened?

HSS sharpens easily; carbide needs a diamond wheel and the edge geometry must be preserved. Lose the geometry and the finish suffers.

Wood Cutting Blades

This group collects the cutters that remove material in woodworking machines; edge geometry sets the finish and material sets the life. The catalogue holds 14 products.

Choosing a cutter

Carbide (TCT) lasts many times longer than HSS in abrasive materials such as MDF, chipboard and laminate. HSS takes a keener edge in solid timber and sharpens easily.

A dulling edge shows first as burn marks and fuzzing on the surface; at that point sharpen or replace, because forcing it strains machine and workpiece.
