TCMT16T304 AH8015 TCMT turning insert by Tungaloy — PVD-coated carbide, 0.4 mm radius

A TCMT16T304 AH8015 Tungaloy turning insert designed for ISO-compliant external and internal turning, optimised for heat-resistant alloys and general turning applications

• PVD-coated carbide for wear resistance
• Triangular TCMT form, 60° included angle
• 0.4 mm corner radius for precise profiling
• Single-sided chipbreaker, with central hole and countersink

Stable cutting performance for demanding turning operations

The PVD-coated carbide grade AH8015 combines wear resistance and edge stability, making it a dependable choice for machining heat-resistant alloys and other demanding materials. The insert’s geometry — a 60° triangle with a 0.4 mm corner radius — provides a balance between profile accuracy and cutting strength, so the component surface finish and dimensional control improve while tool life remains consistent. Compatibility with holders is determined by form, relief angle, tolerance class, clamping arrangement, size and thickness, which ensures secure seating and repeatable positioning during production.

Practical benefits of the single-sided chipbreaker and ISO form

A single-sided chipbreaker simplifies chip control in many turning scenarios and reduces process variability when paired with a suitably rigid toolholder. The ISO TCMT form is widely supported by external holders and boring bars, enabling fast indexable insert changes and minimal setup time. The insert’s central feature — a cylindrical hole with a single-side countersink (40°–60°) — allows standard clamping systems to deliver consistent clamp force, which in turn reduces vibration and contributes to improved surface integrity on turned parts.

Material guidance and machining recommendations

This indexable insert, produced from cemented carbide, is intended as a first choice for general machining of heat-resistant alloys and comparable materials; the AH8015 grade is balanced for wear resistance and edge stability. For best results, match the chipbreaker and grade to the workpiece alloy and machining stability: more rigid set-ups benefit from sharper edge geometries, while less stable conditions profit from the 0.4 mm radius and robust edge preparation. The relief angle of 7° supports effective chip formation and helps maintain tool life across continuous and interrupted cuts.

FAQ

What does the designation TCMT16T304 indicate? TCMT denotes the triangular insert form; 16 indicates the size, and 16T304 refers to the ISO-style dimensions and chipbreak geometry used for the TCMT16T304 AH8015 Tungaloy insert.

Which workpiece materials are suitable for this insert? The AH8015 grade is optimised for heat-resistant alloys and general-purpose turning; the cemented carbide substrate with PVD coating supports good wear resistance and edge stability on these materials.

How is the insert clamped in the holder? The insert features a central cylindrical hole with a single-side countersink (40°–60°), designed for standard clamping systems that ensure repeatable seating and stable fixation of the TCMT16T304 insert.

Can the 0.4 mm corner radius be used for profiling? Yes, the 0.4 mm corner radius provides fine profile control and improved edge strength, making it suitable for accurate finishing passes and where a small radius is required for component geometry.

Is the chipbreaker suitable for a range of turning operations? The single-sided chipbreaker offers reliable chip control for many turning tasks; selection of the exact breaker and cutting parameters should match the workpiece alloy and machining stability for optimal performance.
