Increased Die/Mold Tool Life
The new carbide material and new coating combination in RobbJack’s DM/MDM Die/Mold Carbide End Mill lasts 450% longer than comparable carbides and coatings designed for hard metal applications—and reduces wear by 909%.
Hard milling applications are becoming more complex with tighter tolerances. Poor tool life requires tool changes in the middle of a job, magnifies difficulty and leads to scrapped parts.
Tests were conducted in D2 58 HRc, pitting comparable carbides and coatings against our new DM/MDM Die/Mold Carbide End Mills. We compared tool life and tool wear.
Typical tools designed for hard metal machining had a wear land or deep notches of .0275”. The new RobbJack DM/MDM series tool outperformed every test tool with a smooth wear land of only .0025”. That’s a whopping 909% less wear.
The RobbJack DM/MDM with revolutionary new carbide and coating lasted so much longer than any other tool we were able to cut molds in difficult material 450% longer—completely eliminating the need to switch tools midway through and hope for the best. The new tools generated less heat, held size, and cut the part within tolerance.
- Better finishes that eliminate or reduce the need for polishing
- Tighter tolerances and longer lasting in difficult areas like parting lines
- Great for materials up to 70 HRc
- Higher temperatures
- Reduced cycle times
- Excellent precision
- Dry cutting ability
Before: Typical hard metal carbide grade and coatings for molds.
After: New revolutionary carbide grade and coating. “The one to get it done.”
