TCMT 16T312 T9215 turning insert by Tungaloy — CVD-coated carbide, 1.2 mm radius

TCMT 16T312 T9215 is an ISO-format triangular turning insert for general external and internal turning with a 7° clearance angle and a 60° included angle

• CVD-coated carbide grade T9215
• Triangular ISO insert, 60° included angle
• 1.2 mm corner radius for strength
• Central hole with countersink for secure clamping

Optimised cutting performance for medium steel

The CVD-coated carbide grade T9215 is developed for the middle-range steel machining sector and combines high wear resistance with robust fracture toughness. This composition supports continuous to light interrupted cuts, resulting in longer tool life and fewer insert changes. The grade is designed to maintain cutting-edge stability under typical shop conditions, which helps maintain batch consistency and reduces downtime in production environments.

Geometry that secures a repeatable, accurate cut

A triangular ISO geometry with a 60° included angle and 7° clearance provides a stable cutting edge and flexible indexing options. The 1.2 mm corner radius increases edge strength for roughing passes while preserving surface quality in finishing steps. A central cylindrical hole with a one-sided 40°–60° countersink enables confident clamping in compatible holders, ensuring positional accuracy and repeatability across inserts and tools in the same system.

Reliable chip control and straightforward system integration

The one-sided chipbreaker geometry improves chip formation for the targeted materials and cutting modes, reducing the risk of built-up edge and improving surface integrity. As part of an ISO insert system, the plate integrates with standard external holders, boring bars, clamping kits and replacement screws. Where process stability and productivity are priorities, this solution supports high-volume throughput without sacrificing component quality or machine availability.
