CPMT 09T308 T9215 turning insert — Tungaloy

The CPMT09T308 T9215 Tungaloy insert is an ISO-indexable turning insert for external and internal turning, optimised for medium-steel applications and suited to continuous to light interrupted cuts

• ISO-indexable rhombic insert
• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• Cylindrical hole with countersink

Increased productivity through a high‑performance grade

The CVD-coated carbide T9215 grade combines elevated wear resistance with high fracture toughness, which translates into extended tool life and fewer insert changes on the shop floor. For operations running long, uninterrupted material removal the hard, wear-resistant coating maintains edge integrity while the robust substrate reduces the risk of chipping under stable conditions. This balance of properties means tangible gains in machining uptime and consistent part output when machining medium‑hard steel alloys.

Reliable fit and predictable geometry in ISO systems

Designed to the ISO designation 09T308, the rhombic form and the 11° clearance angle ensure consistent engagement with standard holders across ISO turning systems. Compatibility with a holder is determined by shape, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters preserves cutting geometry and repeatability. The standardised form reduces setup uncertainty and helps to maintain dimensional accuracy across serial production runs, simplifying tool‑room planning and inventory management.

Secure clamping and efficient chip control for stable cuts

The insert’s cylindrical hole with one‑sided countersink (40°–60°) provides positive seating and repeatable clamping force, contributing to vibration damping and stable cutting. A single‑sided chipbreaker and a corner radius of 0.8 mm promote controlled chip formation and evacuation, improving surface finish while protecting the cutting edge under moderate interruptions. The plate thickness (3.97 mm) and rhombic shape combine to give a rigid contact area, supporting higher feeds and steady metal removal rates without compromising process reliability.

FAQ

What materials is this insert best suited for?
The CPMT09T308 T9215 insert is optimised for medium steel machining; the T9215 grade balances wear resistance and toughness for productive results on such materials.

How does the CVD coating affect performance?
A CVD-coated carbide layer on the CPMT09T308 T9215 provides improved thermal and abrasive wear resistance, extending edge life under continuous cutting conditions and enabling higher sustained cutting speeds.

Which holder parameters must match for correct fit?
Compatibility depends on the insert form, clearance angle (11°), tolerance class, fastening method, size and thickness; keeping these aligned with the holder ensures repeatable seating and geometry.

Is the insert suitable for interrupted cuts or only continuous cutting?
The T9215 grade is intended primarily for continuous to light interrupted cuts; it offers fracture resistance for occasional interruptions but is optimised for stable, productive cutting.

Why does the hole and countersink geometry matter?
The cylindrical hole with a one‑sided countersink (40°–60°) on the CPMT09T308 ensures secure clamping and accurate seating, which reduces vibration and maintains consistent cutting performance.
