WNMG080412-AS T9215 – ISO turning insert, CVD-coated carbide with AS chipbreaker (Tungaloy)

A WNMG080412-AS T9215 indexable insert designed for ISO-compliant turning operations, optimised for medium steel machining with reliable chip control and long tool life

• CVD-coated carbide T9215 grade
• Optimised AS chipbreaker for steel
• ISO WNMG 080412 geometry
• 80° trigon shape with cylindrical hole

Consistent productivity for medium steel turning

The T9215 grade combines a CVD coating with a tough carbide substrate to deliver high wear resistance and enhanced fracture toughness. This balance makes the insert particularly suitable for continuous and slightly interrupted cuts in medium-strength steel, where machining stability and repeatable tool life are priorities. By selecting this grade, production processes gain fewer tool changes and more predictable component tolerances, supporting efficient batch runs and stable cycle times.

Geometry and holder compatibility that reduce setup time

The ISO WNMG 080412 geometry (trigon form) with an 80° angle and a 0° relief is designed for a broad range of standard external and internal turning operations. The insert thickness of 4.76 mm and the cylindrical locating hole ensure positive clamping in compatible ISO holders; compatibility depends on form, free angle, tolerance class, fastening method, size and thickness. For workshop planning, the clear dimensional references simplify holder selection and reduce the risk of mismatched interfaces during tool changes.

Predictable chip control and surface quality

The AS chipbreaker is tailored for steel applications and promotes short, controlled chips under stable cutting conditions, which aids in safe chip evacuation and consistent surface finishes. With a 1.2 mm corner radius the insert supports good surface integrity without excessive cutting forces, making it a reliable choice when balancing component finish and productivity. This controlled behaviour reduces rework and downstream cleaning operations, contributing to a smoother manufacturing flow.

Practical use cases and process recommendations

Designed as a first choice for medium steel machining, the insert integrates into the ISO turning system together with a suitable external holder or boring bar, shim/clip sets and replacement screws. Typical uses include external profiling, shoulder turning and light interrupted turning where a combination of tool life and chip control is required. When machining harder or more challenging materials, select a different chipbreaker or grade appropriate to the workpiece and cutting conditions to maintain process security.

FAQ

Which holders are compatible with this insert? Compatibility is determined by the ISO WNMG form, the insert thickness (4.76 mm), the locating hole style and the tolerance class; the WNMG080412-AS T9215 fits standard ISO WNMG holders designed for 080412 geometry.

Is the T9215 grade suitable for interrupted cuts? The T9215 grade is designed for continuous to slightly interrupted cuts in medium steels; for heavy interruptions consider a tougher grade or a different chipbreaker.

What surface finish can be expected with this chipbreaker and radius? With the AS chipbreaker and a 1.2 mm corner radius, expect consistent surface quality for general turning tasks in medium steel while maintaining effective chip control.

Can this insert be used for internal turning? Yes, the insert is suitable for internal turning when combined with an appropriate boring bar that accepts ISO WNMG inserts and provides correct support and rigidity.

How should the chipbreaker choice be adapted for different steels? Choose a chipbreaker and grade according to workpiece material, cutting strategy and machine rigidity; the AS chipbreaker is optimised for steels and offers good chip control under stable cutting conditions.
