Complete Guide to Mitsubishi Materials Cutting Tools: History, Product Lines & Grade Selection
About Mitsubishi Materials
Mitsubishi Materials Corporation’s cutting tool division is part of the Mitsubishi Group, one of Japan’s largest industrial conglomerates. The company’s roots in cemented carbide production trace back to 1931 when Mitsubishi began manufacturing tungsten carbide in Japan. The modern Mitsubishi Materials Corporation was formed in 1990 through the merger of Mitsubishi Metal and Mitsubishi Mining. The cutting tools division, headquartered in Tokyo, Japan, is a global leader in carbide insert technology, particularly renowned for its VP-coating (Vapor deposition Physical) technology and Smart Miracle™ end mill series. Mitsubishi Materials operates manufacturing facilities in Japan, Thailand, China, the United States, and Europe, with distribution in over 50 countries. With 11,347 products on Hooguu, Mitsubishi Materials offers one of the most technologically advanced cutting tool portfolios available.

Turning Inserts
Mitsubishi’s turning insert range features the UE6110, US6110, MC6015, and MC6025 grade series utilizing the company’s proprietary VP15TF and VP25ML coating technologies. The VP (Vapor deposition Physical) coating process creates nano-structured multi-layer PVD films with superior adhesion and wear resistance. The MA (Multi-Arc) coating series delivers ultra-fine grain coatings for precision finishing. Popular insert geometries include CNMG, WNMG, DNMG, and CCMT with chipbreaker designations of H (heavy), M (medium), and L (light). The NX2525 cermet grade is Mitsubishi’s flagship finishing grade for steel, offering exceptional surface finish quality. The UC5105 CBN grade handles hardened steel turning up to 68 HRC.
Milling Cutters
Mitsubishi’s milling portfolio is led by the Smart Miracle™ solid carbide end mill series, featuring variable helix geometry with unequal flute spacing for superior chatter suppression. The VF-2SB (2-flute ball nose) and VF-4MB (4-flute square) are industry benchmarks for die and mold machining. The AWS indexable face mill family provides 45-degree and 90-degree configurations with helical insert placement. The AJX series features indexable shoulder mills for precise 90-degree wall milling. Mitsubishi’s Octa Cuts™ face mills use octagonal inserts with 8 cutting edges for economical heavy-duty face milling. The CMX modular milling system allows quick tool changes between different milling operations.
Drilling Tools
The ZET1 indexable drill system is Mitsubishi’s primary drilling platform, featuring self-centering carbide tips with internal coolant delivery. Available in 2xD, 3xD, and 5xD configurations. The WSTAR™ solid carbide drill series provides high-precision drilling with MWS coating technology for extended tool life in hardened steels and stainless alloys. Mitsubishi also offers the MWS Deep Drill series for deep-hole drilling up to 20xD with gundrill and BTA technology.
Grooving & Threading
Mitsubishi’s MGV grooving insert system offers double-ended inserts with widths from 2 to 6 mm for external and internal grooving. The MGE series provides single-point grooving inserts for profiling and recess machining. For threading, the Mitsubishi Thread Turn range includes partial and full-profile inserts with IR, ER, and NR geometries. The VP coating on threading inserts significantly improves tool life in stainless steel and exotic alloy threading compared to uncoated alternatives.
