About 60° Triangle Inserts (T-Style)
The ISO 1832 T-shape family delivers a 60° included-angle cutting edge — the strongest geometry in turning, with the largest nose radius per IC size. Mitsubishi's 60° lineup covers two clearance variants:
- TC (7° negative rake) — Strong cutting edge for roughing steel, stainless, and cast iron. Compatible with standard negative turning holders (MTJNR/L, PTFNR/L, etc.).
- TP (11° positive rake) — Sharp edge, low cutting force, ideal for finishing, profiling, and slender shaft work. Less common rake than 7° but chosen for specific geometries (TPGH/TPGX for profiling, TPMH for boring).
Each clearance family branches into three chip-breaker variants: G (one face chip-breaker, sharp edge), M (chip-breaker on both faces, double-edged economy), and W (no chip-breaker, used as brazed or flat profiling edge). Combined with three tolerance classes — G (ground periphery), M (precision molded), X (sharp-ground for aluminum) — Mitsubishi offers 7 distinct T-style SKUs to cover profiling, semi-finishing, finishing, and boring.

TCGT — Negative 7° (G chip-breaker)
4 SKUs. Ground-periphery tolerance (G-class) with chip-breaker on one face only — used when sharp-edge profiling is required without sacrificing negative rake strength.
VP15TFNX2525
TCMW — Negative 7° (W: no chip-breaker)
3 SKUs. Solid (no chip-breaker) 60° negative insert. Used for cast iron turning where chip-breaking is not needed, and as a flat-edge profiling tool in tool & cutter grinding.
HTI10
TPGH — Positive 11° (G: one-face chip-breaker, H tolerance)
27 SKUs. Most popular 60° positive turning insert. Chip-breaker on one face with H (precision) tolerance. Used for finishing, profiling, and slender shafts where low cutting force is critical.
VP15TFNX2525HTI10
TPGX — Positive 11° (G chip-breaker, X tolerance)
11 SKUs. Ground-periphery X (super-sharp) tolerance with chip-breaker on one face. The X tolerance class is reserved for aluminum and non-ferrous profiling where a mirror-finish edge is required.
HTI10NX2525
TPMH — Positive 11° (M chip-breaker, H tolerance)
17 SKUs. M-style chip-breaker (both faces) on positive 11° with H tolerance. The MV / FV chip-breaker geometries are specifically designed for internal boring bars — low cutting force, excellent chip control in small diameters.
VP15TFUS735NX2525UE6020
TPMN — Positive 11° (M chip-breaker, N tolerance)
9 SKUs. N-tolerance (precision molded) with M chip-breaker — the heavy-duty positive option. TPMN22 size class handles roughing of cast iron, large-diameter profiling, and interrupted cuts where the strongest positive edge is needed.

TC vs TP vs CCMT vs TCMT — 4-Way Geometry Comparison
Where does the 60° T-shape fit among Mitsubishi's turning lineup? This table compares T-style 60° against the more common C-style 80° and D-style 55° inserts.
| Attribute | TC (60° neg.) | TP (60° pos.) | CC (80° neg.) | DC (55° pos.) |
|---|---|---|---|---|
| Included angle | 60° | 60° | 80° | 55° |
| Clearance (rake) | 7° negative | 11° positive | 7° negative | 7° positive |
| Edge strength | ★★★★★ (strongest) | ★★★ (sharpest) | ★★★★ | ★★★ |
| Best for | Roughing, heavy | Profiling, finishing | General turning | Profiling, light |
| Nose radius (max / IC) | 0.4 (largest) | 0.4 | 0.4 | 0.2 (smallest) |
| Common holders | MTJNR/L, PTFNR/L | MTJNR/L + boring bar | DCLNR/L, PCLNR/L | SDJCR/L, PDJNR/L |
| Surface finish | Good | Excellent (low force) | Good | Best (small nose radius) |
| Common workpiece | Steel, cast iron | Steel, stainless, aluminum | Steel, cast iron | Shaft, slender parts |
| Catalog count (Mitsubishi) | 36 (TCMT/TCGT/TCMW) | 64 (TPGH/TPGX/TPMH/TPMN) | 25+ (CCMT/CCMW) | 15+ (DCMT/DCGT) |
| Best grade pairing | UE6020, UC5115 | VP15TF, NX2525, HTI10 | UE6020, VP15TF | VP15TF, F7030 |
Bottom line: Pick TC when you need maximum edge strength for roughing or interrupted cuts. Pick TP for profiling, finishing, and internal boring where low cutting force is critical. For general profiling, CCMT remains the most popular, but TPGX/TPGH/TPMH offer a sharper edge and better surface finish in finishing operations.
How to Choose the Right 60° Triangle Insert — 3-Step
Step 1 — Identify the Operation
- Roughing / heavy depths (> 3 mm): Choose TC-class (TCMT, TCGT) with N-tolerance or M-class chip-breaker. Negative rake handles higher feed rates.
- Finishing / profiling / boring: Choose TP-class (TPGH, TPGX, TPMH-MV). Positive 11° rake reduces cutting force and improves surface finish.
- Aluminum / non-ferrous: Choose TPGX-HT (X tolerance, uncoated HTI10) for sharp edge retention.
Step 2 — Match the Grade to Workpiece
- Steel (P-grade): UE6020 / UE6110 (CVD 2nd gen) for general use, US735 for stainless, VP15TF for finishing or universal application.
- Cast iron (K-grade): UC5115 (CVD coated) or UTI20T (uncoated heavy).
- Aluminum (N-grade): HTI10 (uncoated sharp edge). F7030 (PVD aluminum-specific) also stocked for some series.
- Mirror finishing: NX2525 cermet (TPGH / TPGX / TPMN grades).
Step 3 — Verify Holder Compatibility
- TC (60° negative): Use negative turning holders — Lever Lock System External Holder, Double Clamp System External Holder, or Multi-Lock System External.
- TP (60° positive): Use positive turning holders with 60° lead angle (PTTNR/L for TPG-style, or boring bars for TPMH-MV).
- Internal boring (TPMH-MV): Use boring bars with T-style pockets (e.g., Screw-On System Boring Bar with T insert pocket).
Frequently Asked Questions
What is the difference between TC and TP 60° triangle inserts?
TC has a 7° negative clearance (stronger edge for roughing), while TP has 11° positive clearance (sharper edge, lower cutting force for finishing). Use TC for steel roughing and interrupted cuts, TP for profiling, finishing, and internal boring on slender shafts.
Why does this collection only have TP and TC types but the handle says TB / TP / TC?
TB (5° positive clearance) is a rare legacy variant — very few Mitsubishi insert series offer TB geometry today, and we do not currently stock any. If you need TB-style inserts for a specific holder pocket, please request a quote — we can source on-demand within 5-7 days from our OEM partners.
What does the second letter (C vs P vs M) mean in TCMT vs TPGH vs TPMH?
The second letter is the clearance angle class: C = 7° negative, P = 11° positive. The third letter indicates the chip-breaker type: M = chip-breaker on both faces (double-edged economy), G = chip-breaker on one face (sharp edge), W = no chip-breaker (flat edge). The fourth letter is tolerance: T = standard (T-class), H = precision (H-class), G = ground periphery, N = precision molded, X = super-sharp ground.
Which grade is best for stainless steel 304/316 turning with TPGH inserts?
For stainless 304/316, we recommend VP15TF (PVD Al-rich "Miracle Coat") as the primary choice — its sharp cutting edge with alumina coating handles austenitic stainless without built-up edge. For heavier roughing, US735 (CVD steel grade) is also stocked. Cermet NX2525 works for finishing stainless at low feed rates but is not recommended for interrupted cuts.
What is the difference between TPGH and TPGX?
TPGH uses H tolerance (precision ±0.025 mm, suitable for general profiling and finishing), while TPGX uses X tolerance (super-sharp, ±0.013 mm, reserved for aluminum and non-ferrous profiling where maximum sharpness is critical). TPGX is essentially a sharper, more precise version of TPGH for the same insert geometry — choose TPGX for aluminum and TPGH for steel/stainless finishing.
What is the smallest and largest 60° triangle insert you stock?
Smallest: TCGT060102L-F (6.0 mm inscribed circle, 0.2 mm nose radius, super-precision for small-diameter profiling). Largest: TPMN220412 (22.0 mm IC, 1.2 mm nose radius, heavy-duty roughing of cast iron and large shafts). We also stock the full intermediate range (TCMT 11 / 16, TPGH 11 / 16, TPMH 08 / 16).
