TPMT16T308-TSF T9225 — ISO triangular indexable insert for turning, CVD-coated carbide, 0.8 mm radius (Tungaloy)

A TPMT16T308-TSF T9225 is an ISO triangular indexable insert engineered for medium to heavy steel turning, combining a durable CVD-coated carbide grade with a TSF chipbreaker for controlled chip formation.

• CVD-coated carbide grade T9225 for steel
• 11° clearance angle for secure engagement
• ISO triangular insert, 0.8 mm corner radius

Reliable cutting performance under mixed conditions

The TPMT16T308-TSF T9225 combines a CVD coating with a tough carbide grade T9225, delivering stable cutting across fluctuating engagement conditions. The CVD layer increases heat resistance and adhesion strength, which helps maintain edge integrity during longer cycles and variable depths of cut. For workshops seeking consistent part quality, this results in fewer indexings and lower tool-change frequency, directly improving uptime and process reliability.

Secure seating and repeatable geometry for consistent components

Conformity with ISO 16T308 ensures predictable interfacing with compatible external toolholders; the 11° clearance angle and the defined 3.97 mm thickness give secure clamping and repeatable seating at every index. Consistent seating reduces micro-movement and runout, which supports dimensional stability on turned faces and shoulders. Specified tolerance and form conformity help integrate the insert into existing setups with minimal adjustment.

Controlled chip formation for safer machining and longer life

The TSF chipbreaker is designed to moderate chip flow during external and internal turning, improving evacuation and reducing re-cutting of chips in interrupted or unstable cuts. Paired with the 0.8 mm corner radius, it produces robust edge strength for profile features while limiting vibration transmission. This controlled chip behaviour reduces thermal peaks on the cutting edge and contributes to predictable wear, which supports longer tool life and fewer scrap parts.

Practical system setup and selection advice for efficient production

Delivered as an ISO indexable insert, the unit is intended for use with a matching holder, shim and screw set in a complete system. Selection should match chipbreaker, grade and geometry to the workpiece material and the machine–workholding stability; choosing the correct combination reduces cycle time and optimises cost per component. For changeover planning, the defined ISO designation and hole/countersink detail simplify inventory management and rapid replacement.

FAQ

What cutting tasks suit this insert best? The TPMT16T308-TSF T9225 is intended for medium to heavy steel turning operations where variable engagement or slightly interrupted cuts demand a tougher, CVD-coated carbide grade.

How does the TSF chipbreaker improve machining? The TSF chipbreaker on this insert promotes controlled chip formation and evacuation, which reduces re-cutting and helps maintain consistent surface finish and tool life with the TPMT16T308-TSF T9225.

Is the insert compatible with standard ISO holders? Yes, the ISO 16T308 designation and defined form, clearance and thickness allow compatibility with ISO external holders when the holder matches the insert’s form, angle and tolerance class.

What advantages does the 0.8 mm corner radius provide? A 0.8 mm radius increases edge strength for robust profiles and improves resistance to mechanical shock, helping to extend effective cutting life during heavier passes.

Which materials should be avoided with this grade? The grade is optimised for medium to heavy steel turning; materials outside this scope should be evaluated for compatibility, and specific cutting data should be confirmed prior to production runs.
