TPMT 110308 T6215 — ISO triangular turning insert for turning, Tungaloy

The TPMT 110308 T6215 is an ISO triangular indexable insert designed for productive external and internal turning, optimised for stainless steel under stable to mildly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• 60° triangular ISO insert for turning
• Optimised for stainless steel turning
• Cylindrical hole with 40°–60° countersink

Consistent surface finish through defined geometry

The 60° ISO triangular insert geometry and the corner radius 0.8 mm provide a predictable contact area that supports consistent surface quality during finishing and semi‑finish operations. The modest corner radius reduces vibration sensitivity compared with larger radii while still allowing for light corner reinforcement. Combined with the 11° relief angle, this geometry minimises rubbing and heat build‑up at the flank, which in turn helps to maintain dimensional stability over longer tool life. The result is repeatable part accuracy and fewer in‑process corrections.

Durable performance in stainless steel machining

The CVD‑coated carbide composition of grade T6215 delivers elevated resistance to built‑up edge and flank wear when machining stainless steel, especially under stable cut conditions. The coating promotes thermal and chemical stability at the cutting edge, helping to avoid premature wear that commonly occurs when machining austenitic stainless grades. Paired with the TSF chipbreaker, the insert supports controlled chip formation for safer chip evacuation and reduced workpiece surface damage, which contributes to higher productivity and fewer part rejections.

System compatibility and secure mounting

Compatibility with holders depends on form, relief angle, tolerance class, fastening method, size and thickness; this insert’s ISO designation 110308, 3.18 mm thickness, and the cylindrical hole with single‑side countersink (40°–60°) are specified to fit standard ISO external holders and boring bars. The central hole and countersink arrangement ensure reliable clamping and consistent seat location, which is essential for maintaining repeatable positioning and tool run‑out control in production setups. Correct selection of the matching insert seat and clamp set simplifies changeovers and reduces setup time.

Practical selection and operating guidance

For turning tasks choose the TSF chipbreaker and the T6215 grade when a balance of wear resistance and chip control is required for stainless steel. For heavier interruptions or unstable setups consider a more robust clamping strategy or a different chipbreaker variant to favour impact resistance. The insert forms part of a typical system build: ISO insert, corresponding external holder or boring bar, shim/clamp set and replacement fastening screws. When in doubt, assess holder fit and insert seating to ensure conformity with ISO tolerances and secure performance.

FAQ

What materials is this insert designed for?
The TPMT 110308 T6215 insert is formulated primarily for stainless steel machining under stable to lightly interrupted conditions, using the CVD‑coated T6215 grade and TSF chipbreaker for controlled chip formation.

Which chipbreaker is supplied and what is its benefit?
The insert features the TSF chipbreaker, which promotes short, manageable chips and improved surface integrity when turning steels and stainless steels, reducing entanglement and easing evacuation.

How is compatibility with holders ensured?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; the ISO designation 110308, 3.18 mm thickness and the central cylindrical hole with countersink match standard ISO seats and clamping systems.

What operational geometry affects cutting performance?
Key geometry parameters are the 60° triangular shape, corner radius 0.8 mm, and 11° relief angle, which together balance edge strength, surface finish and heat contact, impacting tool life and part accuracy.
