*Chamfer Feature providing a 45 Deg. Chamfer at the intersection of the bore and the walls of the broached section when cut to full depth is available by specifying a "-C" in the EDP# for example — 99207-C.
**It is necessary on larger cuts 12 mm or 1/2 inch Keyways and above to cut in two operations, a roughing pass with a smaller width insert (approximate 1/2 required width) and finishing pass at the desired width. This approach reduces the pressure required.
