TCMT 16T308 T9215 Tungaloy turning insert — CVD-coated carbide, triangular ISO insert for turning

TCMT 16T308 T9215 is an ISO-standard triangular indexable turning insert designed for medium steel machining, optimised for continuous to mildly interrupted cuts and high productivity.

• ISO triangular insert TCMT 16T308
• CVD-coated carbide T9215 for medium steel
• Single-side chipbreaker, 0.8 mm corner radius
• 7° relief, cylindrical hole with 40°–60° countersink

Enhanced productivity through CVD-coated carbide

The combination of CVD-coated carbide and the T9215 grade provides a balance of wear resistance and fracture toughness, making this insert well suited to medium steel turning where consistent performance is required. The coating reduces flank and crater wear during longer cutting cycles, which translates into fewer indexings and higher machine availability. Technical terms: CVD (chemical vapour deposition) applies a hard coating layer that improves surface durability without significantly reducing substrate toughness, allowing for reliable performance under steady cutting speeds.

Secure seating and ISO compatibility for reliable clamping

Designed to the ISO geometry 16T308, the insert guarantees predictable fitment and repeatable clamping when combined with a matching external holder or boring bar. The cylindrical hole with single-sided countersink (40°–60°) ensures secure screw engagement and stable seating, reducing micro-movements that can cause chatter or premature edge damage. Clear dimensional conformity (size 16, thickness 3.97 mm) simplifies tool management and minimises set-up time on production lines, supporting continuous, high-throughput machining.

Controlled chip formation and surface quality

The single-side chipbreaker geometry, paired with a 0.8 mm corner radius and a 7° relief angle, delivers controlled chip flow and consistent surface finish on turned parts. A smaller corner radius helps maintain dimensional accuracy on lighter cuts, while the chipformer redirects swarf for efficient evacuation in typical turning setups. For operations encountering occasional interruptions, the grade’s toughness reduces the risk of edge chipping, offering a secure compromise between tool life and component quality.

Practical selection and machining guidance

Selection advice: choose the T9215-coated insert for medium steels where a balance of productivity and edge stability is critical. For heavier interrupted cuts or particularly abrasive materials, consider higher-toughness grades; for higher-speed, light-cut finishing, a finer radius and optimised speeds improve surface integrity. Assembly considerations include matching holder geometry, correct clamp torque, and ensuring the seating surface is clean and free of burrs to achieve the insert’s designed performance.

FAQ

What materials is this insert best suited for?
The T9215 CVD-coated grade is primarily intended for medium steel machining; the insert provides a compromise of wear resistance and toughness that supports productive turning operations.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm radius offers improved edge strength over smaller radii while maintaining dimensional control, making it suitable for general finishing and light to moderate turning cuts.

Is the insert compatible with ISO-standard holders?
Yes — the insert follows ISO geometry 16T308, so compatibility depends on matching holder form, relief angle, tolerance class, fastening and thickness.

Can this insert handle interrupted cuts?
The CVD-coated carbide and T9215 grade tolerate light to moderate interrupted cuts; for severe interruptions, a higher-toughness grade may be preferable to reduce chipping risk.

What does the cylindrical hole with countersink provide?
The cylindrical hole with a 40°–60° single-sided countersink ensures secure screw clamping and stable seating, which supports vibration resistance and repeatable positioning.
