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).

TC vs TP vs DC vs CN — Triangle Positive vs Other Geometries
Where does the TC/TP 60° positive triangle fit among turning geometries? This table compares TC (7° positive) and TP (11° positive) against DC (55° positive diamond) and CN (80° negative diamond).
| Attribute | TC (60° pos. 7°) | TP (60° pos. 11°) | DC (55° pos.) | CN (80° neg.) |
|---|---|---|---|---|
| Shape | 60° triangle positive 7° | 60° triangle positive 11° | 55° rhombic positive | 80° rhombic negative |
| Clearance | 7° (positive) | 11° (positive, sharper) | 7° (positive) | 0° (negative) |
| Edge strength | ★★★ | ★★ (weakest) | ★★ | ★★★★ |
| Edge sharpness | ★★★★ | ★★★★★ (sharpest pos.) | ★★★★★ | ★★★ |
| Best for | General steel profiling | Ultra-precision finishing | Sharp profiling | General cast iron/steel |
| Max depth of cut | ~ 4 mm | ~ 3 mm | ~ 3 mm | ~ 6 mm |
| Typical IC range | 11-22 mm | 09-16 mm | 5-15 mm | 12-19 mm |

| Common workpiece | Steel, stainless, profiling | Steel, stainless, ultra-finish | Shaft, slender, profiling | Cast iron, steel, stainless |
| Catalog count (Tungaloy) | 28 (this collection) | 18 (this collection) | — | — |
| Best grade pairing | T9115, T9125, NS9530, AH725 | T9115, T9125, NS9530, AH725 | VP15TF, F7030 | UC5115, US735, UE6020 |
Bottom line: Pick TCMT (7° positive) for general steel profiling and finishing on CNC lathes — the 60° positive triangle is one of the most common workhorse geometries. Pick TPMT (11° positive) when you need the sharpest possible edge for ultra-precision finishing. Pick DCMT (55° positive diamond) when sharper profiling is needed (smaller nose radius). Pick CNMG (80° negative) when heavier depth of cut or cast iron is the target.
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.
