Mitsubishi Product Lines
Mitsubishi's catalog covers the five major families of carbide inserts used in CNC production. All families share the same Japanese production line, ISO 9001 quality system, and Mitsubishi's proprietary CVD/PVD coating technology.
Positive Turning Inserts
CCMT, DCMT, RCMT, TCMT, VCMT-style 7° clearance inserts with a hole for top clamp. Best for small parts, slender shafts, and finishing operations. Available in US, NX, and VP grade families with chipbreakers for roughing, semi-finishing, and finishing.
Negative Turning Inserts
CNMG, WNMG, DNMG, TNMG, VNMG, SNMG-style 0° clearance inserts with strong edge geometry. Best for OD turning, facing, profiling, copy turning, and heavy roughing. The workhorse of Mitsubishi's turning line, available in US and NX steel grade families plus MC cermet.
Milling Inserts
APMT, RDMT, RPMT, LNMU-style inserts for face milling, shoulder milling, profile milling, and high-feed milling. Compatible with Mitsubishi WSX, ASX, and SRM tool bodies. The VP-series PVD coating extends tool life in hardened-steel and high-temperature alloys.
Threading Inserts
Partial-profile and full-profile threading inserts (16ER / 16IR / 11ER / 11IR series) for metric, UNC, UNF, BSPT, NPT, and trapezoidal threads. Available in both external and internal geometries, with a strong-edge design for tough materials like Inconel and duplex stainless.
Grooving Inserts
GMG, GMM-style inserts for face grooving, OD grooving, internal grooving, and parting off. Widths from 1.0 mm to 6.0 mm with rigid 3-point clamping for chatter-free cuts. Compatible with MW, GW, and GY tool blocks.

Popular Mitsubishi Grades
Mitsubishi grade families use letter prefixes that hint at the application: "US" (steel, P-grade, CVD), "NX" (steel, second-generation CVD), "VP" (PVD Al-rich for high-temperature steel), "MP" (cast iron, P-grade, CVD ceramic), "MC" (cermet, semi-finishing steel). Here are the most-requested grades stocked at CNCHome-Beyond:

Frequently Asked Questions
Is Mitsubishi as good as Sandvik, Iscar, or Kyocera?
Yes. Mitsubishi is one of the top 3 global carbide insert brands, and many of their grades are direct equivalents to Sandvik GC4325, Iscar IC8150, and Kyocera PR1225 in steel, stainless, and cast iron. Use our cross-reference tools to compare specific grades.
Where are Mitsubishi inserts made?
All genuine Mitsubishi inserts are manufactured in Japan (Mitsubishi Materials Corporation, headquartered in Tokyo, with major production in Kumamoto and other prefectures). Products sold on CNCHome-Beyond are sourced directly from Mitsubishi Japan with full lot traceability.
What is the difference between US and NX grades?
The US series is Mitsubishi's first-generation CVD-coated steel grade family, optimized for finishing and high-speed turning. The NX series is the second generation with a thicker Al2O3 layer, providing longer tool life at slightly lower cutting speeds. NX2525 is the modern default; US735 is preferred for heavy roughing.
What is the smallest order I can place?
For sample evaluation, you can order 5 to 10 pieces per item. Mixed SKUs are allowed in a single shipment. Production orders of 1,000+ pieces qualify for additional volume pricing.
Do you carry the full Mitsubishi catalog?
We stock the most popular CNMG, WNMG, DNMG, TNMG, VNMG, SNMG, APMT, RDMT, RPMT, threading, and grooving geometries. For less common items, lead time from Mitsubishi Japan is typically 2 to 3 weeks via air freight.
What is the warranty on Mitsubishi inserts?
All Mitsubishi products carry Mitsubishi's standard 6-month manufacturing warranty plus CNCHome-Beyond's 6-month quality guarantee. If an insert fails under normal recommended cutting parameters, we replace or credit.
