Mitsubishi CC & CP 80° Diamond Turning Inserts

About Mitsubishi CC/CP 80° Diamond Turning Inserts

Mitsubishi Materials (三菱マテリアル) 80° diamond rhombic positive turning inserts cover the full spectrum of steel, stainless, cast iron, aluminum, and high-temperature alloy turning on CNC lathes. The dominant family is CCMT (80° rhombic, with hole, positive 7° clearance) — Mitsubishi's most popular positive turning geometry, with 50+ SKUs in this catalog. The line also includes specialty CCMW (flat top for cast iron), CCGH/CCGT (lapped/cermet for precision finishing), and CPMH (small IC sizes for finishing). Every insert on this page is genuine OEM Mitsubishi product, manufactured at Mitsubishi's Kyushu Japan facilities. CNCHome-Beyond is an authorized Mitsubishi distributor; orders placed before 3 PM China time ship same-day from our Hangzhou warehouse with DHL/UPS/FedEx express delivery in 3-7 business days.

Mitsubishi Chip-Breaker Reference (10+ Variants)

Mitsubishi's CCMT chip-breaker system is the most comprehensive in the industry. Each chip-breaker is optimized for a specific feed, depth of cut, and workpiece material:

How to Choose a Mitsubishi 80° Diamond Insert

Step 1: Match the geometry to the operation. For 80% of steel turning applications, choose CCMT (80° rhombic, with hole, positive 7°). For cast iron heavy roughing, choose CCMW (flat top, no chip-breaker, regrindable). For aluminum, choose CCGH (lapped, polished). For precision finishing on small parts, choose CCGT (cermet).

Step 2: Match the grade to the workpiece material. Steel → UE6110 (workhorse) or NX2525 (cermet mirror finish). Stainless → US735 (CVD) or VP15TF (PVD Miracle Coat). Cast iron → UC5115 (universal) or MC6015 (ceramic-reinforced). Aluminum → UTI20T (uncoated) or HTI10 (cermet-grade). High-temp alloys (Inconel, titanium) → VP15TF (PVD Al-rich).

Step 3: Match the chip-breaker to feed and depth of cut. Precision finishing (0.03-0.10 mm/rev) → FV. Finishing (0.05-0.12) → FM. Semi-finishing (0.05-0.15) → SV. General purpose (0.10-0.20) → MV. Profiling (0.05-0.15) → LP. Use the table above to find the right combination.

Step 4: Match the insert to the tool holder. Mitsubishi CCMT fits industry-standard PCLNR/L, DCLNR/L, MCLNR/L, MWLNR/L tool holders. CNCHome-Beyond carries compatible aftermarket holders at 30-50% below OEM — see our turning tool holder guide and Insert Holder Selector.

Compatible Tool Holders (Standard Positive 7° Rake)

Mitsubishi CCMT inserts fit the following CNCHome-Beyond tool holder families (all ISO 5610 standard, drop-in compatible with Mitsubishi OEM holders):

• Double-Clamp External Holders (PCLNR/L, DCLNR/L) — for heavy CCMT roughing
• Multi-Lock External Holders (MCLNR/L, MWLNR/L) — for general CCMT medium cutting
• Lever-Lock (P-Type) External Holders — for quick-change high-mix production
• Screw-Clamp Boring Bars (S...PCLNR/L, S...MCLNR/L) — for internal turning with positive inserts

CCMT Series — 80° Rhombic with Hole (Featured: 10 SKUs)

The CCMT is Mitsubishi's most popular positive turning geometry. The catalog covers all 3 IC sizes (06, 09T3, 1204) and the full grade family. The 7° positive clearance reduces cutting force for small lathes and finishing operations.

• CCMT09T308 VP15TF - 9.5mm IC, no CB (workhorse), PVD Miracle Coat universal (most popular 9.5mm size)
• CCMT09T304 US735 - 9.5mm IC, no CB, CVD steel heavy (P20-P40)
• CCMT09T304 UE6020 - 9.5mm IC, no CB, CVD steel finishing (P10-P25)
• CCMT09T304 UE6110 - 9.5mm IC, no CB, CVD steel workhorse
• CCMT09T304 UC5115 - 9.5mm IC, no CB, CVD cast iron workhorse
• CCMT09T304 NX2525 - 9.5mm IC, no CB, cermet (mirror finish)
• CCMT09T304-FV NX2525 - 9.5mm IC, FV precision finish, cermet (mirror)
• CCMT060204 VP15TF - 6mm IC, no CB, PVD universal (small lathe)
• CCMT120408 VP15TF - 12mm IC, no CB, PVD universal (most popular 12mm)
• CCMT120412 UE6020 - 12mm IC (1.2mm nose), no CB, CVD steel

CCMW Series — 80° Rhombic Flat Top for Cast Iron (Featured: 3 SKUs)

The CCMW has no chip-breaker and a flat top, making it the strongest geometry for cast iron heavy roughing. The flat top is regrindable on the periphery for maximum economy.

• CCMW120408 UC5115 - 12mm IC, flat top, CVD cast iron workhorse
• CCMW120408 UC5105 - 12mm IC, flat top, CVD cast iron high-speed finishing
• CCMW120408 HTI10 - 12mm IC, flat top, uncoated aluminum + cast iron

CCGH / CCGT / CPMH Specialty (Featured: 3 SKUs)

Specialty families for aluminum (CCGH lapped), cermet precision (CCGT), and small IC (CPMH). These complement the mainstream CCMT for specific applications.

• CCGT04T002L-F VP15TF - 4mm IC, F precision, PVD (small precision parts)
• CCGH060202L-F VP15TF - 6mm IC, L-F lapped, PVD (aluminum mirror)
• CPMH080204-MV NX2525 - 8mm IC, MV, cermet (small diameter finishing)
