Keyway & Slotting Inserts

The inserts designed to work exclusively with duMONT tool holders are a sintered steel alloy with a 13% cobalt content, heat treated to a 72 HRC hardness providing toughness and impact resistance.

A TiN coating is applied to improve wear resistance and lubricity. All inserts are designed to allow several re-sharpenings.  A chamfer feature is available.

See the Resource Center Tooling Systems – tooling system videos, machining considerations, mounting of inserts and tool holders as well as programming and sharpening.

*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.
