What are the dimensions of TPGN110302?

TPGN110302 has an inscribed circle (d1) of 6.35 mm (0.25 in), thickness s of 3.18 mm (0.125 in) and nose corner radius rε of 0.2 mm (0.008 in), per the ISO 1832 designation.

What does the TPGN110302 designation mean?

TPGN = 60° triangle; 11° clearance; precision tolerance; No fixing hole, no integral chipbreaker.

Is TPGN110302 interchangeable between brands?

Yes for geometry: under ISO 1832 every TPGN110302 from any manufacturer shares shape, inscribed circle, thickness and nose radius. Brand suffixes after the core code (chipbreaker designs such as -PM or -PR, and grade numbers) change chip control and application, not geometry, so confirm the full ordering code and grade before substituting.

Which carbide grade should I use with TPGN110302?

The ISO core code defines geometry only. The grade is selected for the workpiece material (ISO 513 groups P/M/K/N/S/H) and the operation: CVD grades for general steel and cast-iron turning, PVD grades for stainless, superalloys and finishing. Verified, catalog-cited grade equivalents for this model appear in the grade cross-reference table as they are added.

What is TPGN110302 typically used for?

Typical operations: general turning, chamfering, facing. Small inscribed circle — typically finishing, small parts and precision operations.

Cross-brand geometric interchange

Under ISO 1832, every insert carrying the core designation TPGN110302 shares identical geometry — shape, inscribed circle, thickness and nose radius — regardless of manufacturer. Letters after a dash (chipbreaker patterns, grade numbers) affect chip control and application band, not the pocket geometry, and are marked PARTIAL.

Applications & cutting conditions

Typical operations

general turning

Small inscribed circle — typically finishing, small parts and precision operations.

Workpiece materials

All ISO 513 workpiece material groups (P/M/K/N/S/H) depending on the selected carbide grade.

CVD-coated grades are typical for steel (P) and cast iron (K) general turning; PVD-coated grades are typical for stainless (M), superalloys (S) and finishing cuts. Always apply the manufacturer's cutting-data recommendation for the chosen grade.

Selection notes

▸Geometry first, grade second. The same ISO core code is a drop-in pocket fit across brands; the chipbreaker suffix and grade decide performance and must be matched to the cut.
▸Nose radius is a trade-off. A larger rε strengthens the edge and allows higher feeds but raises radial cutting forces and vibration risk; smaller radii suit finishing, fine detail and slender setups.
▸Match clearance to the holder. Positive-clearance codes (B/C/P…) require the matching positive toolholder; 0° N inserts seat on negative holders and offer twice the edges.
▸Tolerance class for the job. G and tighter classes suit precision and finishing; M-class moulded inserts are the economical default for general turning.
▸Pick the chipbreaker for your feed band. Roughing and finishing geometries are not interchangeable in practice even when the core code is identical.
▸Toughness vs wear resistance. Tough grades resist interrupted cuts and scale; hard, wear-resistant grades suit stable, high-speed finishing — choose within the same ISO 513 group.
