About TB / TP / TC 60° Triangle Positive Inserts (T-Style)

The ISO 1832 T-shape family delivers a 60° triangle cutting edge with positive clearance — the most common geometry for general-purpose steel finishing and profiling. Tungaloy's T-family in this collection includes:

• TC (7° positive clearance) — 28+ SKUs. The dominant 60° positive triangle with chip-breaker. IC sizes 11 / 16 mm, with PS (precision semi-finishing), PSS (precision sharp), and 24 (medium cutting) chip-breaker variants.
• TP (11° positive clearance) — 18+ SKUs. Sharper 11° rake for ultra-precision profiling and finishing. IC sizes 09 / 11 / 16 mm, with PS / PSS chip-breaker variants.
• TB (5° positive clearance) — Currently not stocked (sourced on-demand). Less common 5° rake variant.
• TPGT (G-tolerance, ground periphery) — 5 SKUs. Premium cermet wiper geometry for mirror surface finishing at high feed rates.

TC and TP inserts are the workhorse 60° positive triangle turning inserts — used in nearly every production CNC lathe for profiling, semi-finishing, and finishing on steel and stainless. The 60° included angle provides the largest nose radius per IC size, making T-style inserts ideal for both roughing (with chip-breaker) and finishing (without chip-breaker or with sharp cermet).

Tungaloy's TC/TP catalog in this collection features the PS chip-breaker (precision semi-finishing), PSS chip-breaker (precision sharp), and 24 chip-breaker (medium cutting) across 3 IC sizes (09 / 11 / 16) and 4 grade families: T9115 (CVD steel), T9125 (CVD stainless), NS9530 (cermet finishing), and AH725 (PVD universal).

• PSS (Precision Sharp): 3+ SKUs. Sharper variant of PS for finest surface finish.
• 24 (Medium Cutting): 15+ SKUs. Tungaloy's general-purpose medium-duty chip-breaker for profiling.
• W15 (Wide Wiper): 3 SKUs. Wide wiper geometry for IC 16 — high feed + mirror finish.
• W08 (Narrow Wiper): 2 SKUs. Narrow wiper geometry for IC 08 — high feed + mirror finish.

How to Choose the Right TC / TP 60° Triangle Positive Insert — 3-Step

Step 1 — Identify the Workpiece

• Carbon steel / alloy steel: TCMT or TPMT with T9115 (CVD P-grade).
• Stainless steel 304/316: TCMT or TPMT with T9125 (CVD M-grade).
• Mirror finish on steel: TCMT or TPMT with NS9530 cermet (P05-P15).
• Ultra-precision profiling: TPMT (11° positive) with NS9530 cermet.
• High-feed finishing with mirror surface: TPGT-W15 / W08 with NS9530 cermet wiper.
• Universal (steel + stainless): TCMT or TPMT with AH725 (PVD Al-rich).

Step 2 — Pick the Chip-Breaker

• PS (Precision Semi-finishing): Lighter chip-breaker for finishing and profiling at low feed rates.
• PSS (Precision Sharp): Sharpest variant of PS for finest surface finish.
• 24 (Medium Cutting): General-purpose medium-duty chip-breaker for profiling and interrupted cuts.
• W15 / W08 (Wiper): Wiper geometry for high feed + mirror surface (TPGT only).

Step 3 — Verify Holder Compatibility

• TC / TP (60° positive): Use Tungaloy positive turning holder with 60° lead angle (e.g., MTJNR/L or PTGNR/L for TCMT).
• Verify lead angle: 60° matches TC / TP perfectly. Common holders: PTGNR/L 1616-H11 (11 mm IC), PTGNR/L 2020-K16 (16 mm IC).
• Match IC to holder pocket: TC/TP 09 needs 9 mm pocket; 11 needs 11 mm; 16 needs 16 mm.
