An expansion of DoFeed to include new grades


Fukushima, June 2017 – Tungaloy Corporation is continuously expanding on its highly reputed DoFeed series. The latest addition includes inserts in the AH8015 grades.

DoFeed is a high feed milling cutter series with a close-pitched insert alignment, intended for various applications where an efficient removal of large stock is required, such as profiling and pocketing processes in die and mold shops. The ingenious double-sided insert geometry brings benefits in tool economy and productivity and has been earning customers’ confidence in recent years. The series already has an ample lineup of inserts and cutter bodies, intended for milling various materials including steel, stainless steel, cast iron, and heat-resistant super alloys. Backed by popular demands and market requests for machining hard materials over HRc50, a new insert line of the AH8015 grade now joins the product family.

AH8015 is a PVD grade with a coating composition of AlTiN. The multi-layered coating configuration with high aluminum content improves resistance to chipping and built-up edge, improving machinability for smearing materials typically used in the die and mold industry. An extremely hard sub-micron carbide grade is used for the substrate for vastly improved wear resistance.
