TCMT16T312 indexable turning insert, CVD-coated carbide (T505) – Tungaloy

TCMT16T312 is an ISO-standard triangular indexable insert designed for economical and productive turning, especially for cast iron machining.

• Triangular ISO geometry for versatile turning
• CVD-coated carbide grade T505 for cast iron
• 1.2 mm corner radius for stable cuts

High-efficiency turning with reliable chip control

The TCMT16T312 series delivers a focused combination of economic machining and predictable chip formation. Manufactured from CVD-coated carbide in grade T505, the geometry and single-sided chipbreaker are tuned for cutting cast iron under a range of stability conditions. The insert’s triangular shape and a 1.2 mm corner radius provide consistent edge engagement, reducing vibration and leading to longer tool life. Compatibility with ISO holders is determined by form, clearance angle, tolerance class, fastening method, size and thickness, which simplifies integration into existing tool systems.

Ease of installation and secure clamping for production use

This ISO insert features a cylindrical hole with a single-sided countersink (40°–60°) to suit standard retaining screws and clamping pads, ensuring repeatable mounting and minimal setup time. The plate thickness of 3.97 mm and the 16 mm inscribed circle give a robust support area against the holder, while the 7° relief angle helps to reduce rubbing on the flank face during heavy cuts. These measurable parameters allow straightforward selection of cutting parameters and contribute to predictable process windows on automated lathes and turning centres.

Application benefits and material guidance for shop-floor decision making

Designed primarily for turning, the insert is particularly suitable for the efficient machining of cast iron, offering a balance between cutting speed and edge life. The CVD coating improves heat resistance and wear behaviour during interrupted cuts and higher cutting speeds, promoting longer tool life and fewer index changes. For operations with moderate rigidity or where vibration is present, the triangular geometry and single-sided chip control assist in maintaining surface finish without compromising productivity.
