WNMG 080408 T9235 — WNMG 080408 turning insert for steel turning (Tungaloy)

The WNMG080408-TM T9235 is an ISO-standard indexable insert designed for external and internal turning, providing a tough, CVD-coated carbide grade and a TM chipbreaker for interrupted and unstable cutting conditions.

• CVD-coated carbide grade T9235
• For steel: interrupted and unstable cuts
• ISO WNMG 080408 trigon insert, 80° cutting angle
• 0.8 mm corner radius for versatile turning
• Cylindrical-hole fixing, 4.76 mm thickness

Consistent cutting under unstable conditions

The combination of a CVD-coated carbide substrate and the T9235 toughness rating delivers controlled wear behaviour when machining steel at moderate cutting speeds. This composition is selected to maintain a stable cutting edge during interrupted cuts and less rigid set-ups, reducing edge chipping and unexpected tool changes. By favouring toughness over maximum hardness, longevity is improved in applications where vibrations or part spring-back are present, which supports a more predictable production flow and fewer unscheduled interventions.

Improved chip control through optimised geometry

The TM chipbreaker and trigon geometry (WNMG) concentrate chip flow and reduce the risk of long stringy chips on steel. The 80° cutting angle combined with a 0.8 mm corner radius moderates engagement, enabling a balance between strength of the cutting edge and surface finish. In practice, the chipbreaker design channels chips away from the cutting zone, lowering heat concentration and assisting in efficient chip evacuation even during interrupted cuts. Compatibility with ISO holders ensures secure clamping and repeatable positioning for consistent results.

Seamless integration into ISO turning systems

As an ISO-form insert, this grade integrates with standard external holders, boring bars and clamping kits; mounting is achieved via a cylindrical hole and the corresponding screws and underlay. The standardised form, free angle and thickness simplify replacement and inventory management across mixed fleets. Choosing the correct holder geometry and tolerance class is essential for optimal performance; matching the insert form, free angle and clamping system yields the intended cutting angles and repeatability during tool changes.

Target applications and user guidance

Engineered primarily for steel machining, the insert excels when lower cutting speeds and robust edge strength are required—typical in unstable setups or interrupted turning cycles. The product is not designed for extreme high-speed finishing where ultra-hard grades would be preferable; instead, it targets productive material removal with reliable edge life. For selection guidance, consider the workpiece clamping rigidity, depth of cut and expected interruption frequency to pick the correct chipbreaker and grade pairing for each operation.

FAQ

What materials is this insert intended for?
The WNMG080408-TM T9235 (SKU: 6785799-Tungaloy) is optimised for machining steel, particularly where toughness and resistance to chipping under interrupted or unstable cutting conditions are required.

How does the TM chipbreaker affect performance?
The TM chipbreaker on this indexable insert directs and breaks chips effectively during turning, improving evacuation and reducing heat concentration, which benefits tool life and surface integrity when machining steel.

Which holders are compatible with this insert?
Compatibility is determined by ISO form, free angle, tolerance class, fixing method and plate size; the trigon WNMG form fits standard ISO external turning holders and boring bars designed for WNMG inserts.

Is this grade suitable for high-speed finishing?
The T9235 grade is formulated for toughness at lower to moderate cutting speeds and is therefore not optimised for ultra-high-speed finishing operations where harder, less tough grades would be preferable.

What is the correct way to secure the insert?
The insert is secured via its cylindrical hole using the matching screw, underlay and clamp kit specified for the holder; correct clamping torque and clean contact surfaces ensure repeatable positioning and safe operation.
