Complete Guide to Tungaloy Cutting Tools: History, Product Lines & Grade Selection
About Tungaloy
Tungaloy Corporation is a Japanese cutting tool manufacturer with roots dating back to 1929 when it was established as a subsidiary of Tokyo Shibaura Electric (now Toshiba). Originally known as Tokyo Tungsten, the company was a pioneer in cemented carbide development in Japan. In 2007, Tungaloy became a member of IMC Group (International Metalworking Companies), joining Iscar, TaeguTec, and Seco Tools under the same corporate umbrella while maintaining its distinct Japanese engineering identity. Headquartered in Kawasaki, Japan, Tungaloy operates manufacturing facilities in Japan, China, and Thailand, with global distribution in over 40 countries. The brand is renowned for its TungCut grooving system, DoFeed high-feed milling platform, and TurnTungsten turning insert range. With 1,663 products on Hooguu, Tungaloy offers a focused portfolio of high-performance cutting tools that combine Japanese precision with IMC Group’s global resources.

Turning Inserts
Tungaloy’s turning portfolio features the TurnTungsten insert family with grades covering the full ISO application spectrum. The T9115 and T9125 grades utilize the proprietary TungTec CVD coating for steel turning, while T9135 handles heavy roughing with reinforced cutting edges. The NS9530 grade is dedicated to stainless steel machining with PVD coating and sharp edge geometry. The TH307+ cermet grade provides exceptional surface finish for precision steel finishing. Popular insert geometries include CNMG, WNMG, DNMG, and CCMT with Tungaloy’s MS (medium steel), FW (finishing wiper), and RR (roughing) chipbreaker designations. The DualFeed wiper insert enables 2x feed rates while maintaining Ra 0.8 surface finish.
Milling Cutters
Tungaloy’s milling range is anchored by the DoFeed high-feed milling platform, one of the most successful high-feed mill designs in the industry. The DoFeed system uses positive-rake inserts with low cutting forces directed axially, enabling high metal removal rates even on long-reach applications. The DoMAGIC series offers modular milling heads for face milling, shoulder milling, and high-feed milling on common shanks. The DoQuadRush face mill family uses square inserts with 4 cutting edges for economical face milling. Tungaloy’s TungAlloMill solid carbide end mill range covers general-purpose and aluminum-specific geometries with variable helix designs.
Drilling Tools
The DrillMeister indexable drill system is Tungaloy’s primary drilling platform, featuring exchangeable carbide tips with self-centering geometry and internal coolant delivery. Available in 3xD, 5xD, and 8xD depth configurations with diameters from 12 to 50 mm. The TungDrill solid carbide drill series provides high-speed drilling with TungTec coating for extended tool life in steel and stainless steel applications.
Grooving & Threading
The TungCut system is Tungaloy’s flagship grooving platform, featuring double-ended inserts with rigid clamping and optimized chipbreaker geometry. TungCut handles external grooving, internal grooving, and parting-off with widths from 1.5 to 6 mm. The TungThread system offers partial and full-profile threading inserts in metric and Whitworth forms. Tungaloy’s MiniTungCut series provides small-format grooving tools for Swiss-type lathes and precision machining applications.
