Shear scraping with this cutter is NOT recommended. Made with M2 HSS these popular cutters offer excellent sharpness while delivering Robert Sorby HSS reliability. Sharpening: Use a diamond file or honing stone across the top face. To gain best results and increase the longevity of the cutter this simple procedure should be done little and often.
