CPMT 090304 T6215 indexable turning insert — Turning (Tungaloy)

CPMT 090304 T6215 is an ISO-format, rhombic indexable insert designed for stable turning of stainless steels under continuous or mildly interrupted cutting conditions.

• CVD-coated carbide for stainless steel machining
• Rhombic insert, 80° cutting edge geometry
• One-sided chipbreaker for stable cuts
• Central hole with cylindrical seat and countersink

High wear resistance for demanding stainless-steel turning

The CPMT090304 insert combines a CVD-coated surface with a robust carbide substrate to resist abrasive and adhesive wear that commonly occurs when machining stainless steel. The chemical vapour deposition layer improves heat resistance and reduces oxidation at elevated cutting temperatures, which translates into longer intervals between indexings and fewer unplanned tool changes. With an effective cutting angle of 80° and a modest 0.4 mm corner radius, the geometry is tuned to balance edge strength and surface finish, delivering consistent component tolerances on rings, shafts and housings.

Controlled chip flow and secure clamping for predictable productivity

A dedicated one-sided chipbreaker directs chips away from the cutting zone, reducing risk of chip re-cutting and helping maintain machine uptime. The insert’s central cylindrical hole with a single-side countersink (40°–60°) ensures repeatable, vibration-free clamping in compatible holders, supporting stable cutting even under slightly interrupted cuts. This combination of chip control and reliable fixation reduces the chance of burnishing or poor surface quality, improving first-pass yields and process stability.

ISO compatibility and rigid plate design for versatile setup

Produced to the ISO indexable insert series norms, the plate’s rhombic shape and defined parameters simplify holder selection: shape, clearance angle, tolerance class, fastening method, size and thickness determine fit. The 3.18 mm plate thickness and 11° clearance angle give the insert sufficient rigidity for medium-depth turning operations while remaining compatible with a wide range of external holders and boring bars. This standardised approach shortens setup time and makes tool management predictable across batches.

Reliable performance that supports shop-floor efficiency

Designed for machine shops seeking consistent results, this indexable cutting solution promotes stable chip formation and measurable improvements in tool life. The combination of a wear-resistant coating and a dedicated chipformer yields fewer interruptive events, lower scrap rates and smoother finishing passes. For production environments where repeatability and surface integrity matter, the insert delivers a pragmatic balance of performance and economy without introducing complexity into process planning.

FAQ

What materials is this insert designed to machine?
The CPMT090304 T6215 insert is formulated for machining stainless steels, offering a wear-resistant CVD coating and carbide substrate suitable for stable turning operations.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the ISO designation of the CPMT090304 supports use in standard external holders and boring bars designed for 09-sized rhombic plates.

How does the one-sided chipbreaker affect cutting performance?
The one-sided chipbreaker promotes controlled chip formation and evacuation, reducing re-cutting and improving surface finish during continuous or lightly interrupted turning with this Tungaloy insert.

What advantages does the CVD coating provide?
CVD-coated carbide improves thermal resistance and wear protection during machining of stainless steels, which supports longer tool life and steadier dimensional results compared with uncoated grades.

Is the insert suitable for interrupted cuts?
Yes — the T6215 grade and the insert geometry are specified for stable to lightly interrupted turning conditions, offering reliable edge strength for such applications.
