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.
