TurnMaster Square Cutter - Tungsten Carbide

Designed for generating square sections such as shoulders or tenons where a turned part is to be assembled into a hole – a chair leg is good example. This cutter is also useful on the outside of a round form, as well as long straight sections on spindle work. Excellent results can be achieved in shear scraping mode with cutter especially effective shear scraping on the outside of a bowl. This version of the cutter being manufactured with micro grade tungsten carbide will deliver long lasting results.
Use a diamond file or diamond plate flat across the top face. To gain best results and increase the longevity of the cutter this simple procedure should be done little and often.
If the cutter gets chipped use the TurnMaster cutter holder to reshape the profile on the Robert Sorby ProEdge using a diamond belt or on a grinding wheel using diamond or other high density abrasive material.
