TPMT 16T304 T505 triangular turning insert, CVD-coated carbide — Tungaloy

A TPMT 16T304 T505 triangular turning insert designed for efficient external and internal turning of cast iron, offering robust chip control and ISO interchangeability

• CVD-coated carbide grade T505
• CM chipbreaker for cast iron
• Triangular 16 mm insert, 60° included angle
• 0.4 mm corner radius for flexible cutting

Reliable chip control for economic cast-iron turning

The combination of a CVD-coated surface and the T505 carbide grade is tuned for economic machining of cast iron. The CM chipbreaker promotes stable chip formation even under varying cutting conditions, which reduces downtime for chip clearing and helps maintain cutting-edge integrity. For operations where stability and predictable wear are priorities, this specification supports longer tool life and consistent surface finish, making it a practical choice for batch production and routine component turning tasks.

ISO-compatible design that simplifies tool management

Compatibility follows ISO conventions: the insert’s triangular shape, 60° included angle, 11° relief and tolerance class determine fitting to corresponding external holders or boring bars. The system set-up typically comprises an ISO indexable insert, a matching holder or boring bar, a shim/clamp set and replacement screws. The central hole with a cylindrical bore and single-sided countersink (40°–60°) ensures secure clamping and reproducible seat datum. These factors together ease logistics and reduce set-up variability on the shop floor.

Material and geometry for versatile turning results

Constructed from carbide with CVD treatment, the grade is selected for a balance of wear resistance and edge toughness needed in cast-iron applications. The 0.4 mm corner radius enables both light roughing and finishing passes where small radii are beneficial to control cutting forces and surface integrity. For heavier stock removal or interrupted cuts, the CM chipbreaker and the T505 grade provide the necessary robustness; alternatively, selecting larger radii or different grades will better suit heavy-duty or high-feed operations. Overall, the insert’s geometry and coating deliver dependable performance across typical turning cycles.
