RobbJack tools are 100% made in the U.S.A., but we also help our manufacturing customers compete against offshoring competitors. We help them reduce cycle times, lead times, and lower labor costs. With RobbJack, you get a one-shot machining strategy that can reduce or eliminate costly grinding, EDMing and polishing.

RobbJack’s Advanced Applications Testing Facility is available to help solve your die & mold application needs. Send us your material and we will develop a solution.

Hardened Tool Steels, Stainless Steel and Powdered Metals

Hard milling applications in die & mold production are becoming more complex with tighter tolerances. To complicate the matter, poor tool life requires tool changes in the middle of a job that often result in scrapped parts.

The RobbJack DM/MDM Die/Mold Carbide end mill offers tighter tolerances, lasts longer in difficult areas like parting lines, and produces better finishes that reduce or eliminate the need for polishing. It performs well on materials up to 70 HRc and can handle dry cutting and high temperatures. The RobbJack DM/MDM Die/Mold is made of a new carbide material and a new coating combination that lasts 450% longer than comparable carbides and coatings designed for hard metal die & mold applications—and reduces wear by 909%.

The DM/MDM series is the ideal tool for 3D machining when you need quicker feeds, no tool changes mid-job and a cleaner finish that’s consistent over a greater number of parts machined.

The TM/MTM Tuffy Grade Solid Carbide Toroid Style End Mill offers excellent precision when machining tight areas such as ribs and bores.

The HM/MHM Tuffy Grade Die/Mold End Mill excels at delivering a smooth finish on flat open areas.
