About CC 80° Diamond Positive Inserts (C-Style)

The ISO 1832 C-shape family delivers an 80° rhombic cutting edge with positive 7° clearance — the most common 80° positive diamond geometry for general steel turning. Tungaloy's C-family in this collection includes:

• CCMT (M chip-breaker, M tolerance) — 38 SKUs. The dominant 80° positive diamond with chip-breaker on both faces. IC sizes 6.0 / 9.5 / 12.0 mm, with PS (precision semi-finishing), PSS (precision sharp), and 24 (medium cutting) chip-breaker variants.
• CCGT (G chip-breaker, G tolerance) — 7 SKUs. Ground-periphery cermet finishing insert with chip-breaker on one face. Premium 80° positive for mirror surface work on steel and stainless.

CC inserts are the go-to 80° positive diamond turning insert — the 80° included angle provides excellent chip flow and good balance between edge strength and surface finish. Tungaloy's CC catalog in this collection features 5 grade families: T9115 / T9125 (CVD steel / stainless), NS9530 (cermet finishing), AH725 (PVD steel), and J740 (CVD stainless). 4 chip-breaker variants: PS / PSS / 24 / W15 / W20 (Tungaloy wiper chip-breakers) / J10 (Tungaloy ultra-sharp).

All 45 SKUs are spread across 3 IC sizes (06 / 09 / 12), with 09.5 mm IC most common (~25 SKUs). The 6.0 mm IC is for small-diameter profiling; 12.0 mm IC is for general profiling on larger shafts.

How to Choose the Right CC 80° Positive Diamond Insert — 3-Step

Step 1 — Identify the Workpiece

• Carbon steel / alloy steel: CCMT-PS with T9115 (CVD P-grade).
• Stainless steel 304/316: CCMT-PS / PSS with T9125 (CVD M-grade).
• Mirror finish on steel: CCMT or CCGT with NS9530 cermet (P05-P15).
• Universal (steel + stainless): CCMT-PS / PSS with AH725 (PVD Al-rich).
• High-feed finishing with mirror surface: CCGT with W15 / W20 wiper + NS9530 cermet.

Step 2 — Pick the Chip-Breaker

• PS (Precision Semi-finishing): Lighter chip-breaker for finishing and profiling at low feed rates.
• PSS (Precision Sharp): Sharper variant of PS for finest surface finish.
• 24 (Medium Cutting): General-purpose medium-duty chip-breaker for profiling and interrupted cuts.
• W15 / W20 (Wiper, CCGT only): Tungaloy wiper geometry for high feed + mirror surface.
• J10 (Ultra-Sharp, CCGT only): Tungaloy ultra-sharp chip-breaker for finishing stainless steel.

Step 3 — Verify Holder Compatibility

• CC (80° positive): Use Tungaloy SCLC-type positive turning holder with 80° lead angle, or PCLN-type positive holder.
• Verify lead angle: 80° matches CC perfectly. Common holders: SCLCR/L 1616-H09 (9 mm IC), SCLCR/L 2020-K12 (12 mm IC).
• Match IC to holder pocket: CCMT 06 needs 6 mm pocket; CCMT 09 needs 9 mm; CCMT 12 needs 12 mm.
