SCMT 120404 AH6235 turning insert by Tungaloy — PVD-coated carbide, 90° square geometry

SCMT 120404 AH6235 Tungaloy turning insert designed for robust external and internal turning where interrupted cuts and higher breakout risk demand a tougher grade and stable chip control

• PVD-coated carbide grade AH6235
• Optimised for stainless steels and interrupted cuts
• 0.4 mm corner radius for accurate profiles
• ISO square insert, 90° cutting edge

Stable chip control and material coverage for productive turning

The AH6235 grade is a PVD-coated carbide composition formulated for tougher behaviour when machining stainless steels and other demanding alloys. This translates into improved resistance to chipping during interrupted cuts and operations with variable feed, which reduces unplanned insert changes and scrap. The single-sided chipbreaker geometry supports predictable chip formation, aiding coolant flow and chip evacuation; as a result, process stability and cycle-time consistency are enhanced, making the solution attractive for production environments seeking reliable throughput.

Geometry engineered for dimensional accuracy and secure clamping

With a 0.4 mm corner radius, 90° square shape and 7° relief angle, the insert delivers repeatable profile control and edge strength for shoulder and profile turning. The central bore with a cylindrical hole plus a single-side countersink (40°–60°) ensures positive seating and torque transmission in ISO-standard holders, limiting micro-movement under load. The 4.76 mm thickness provides rigidity, reducing deflection on extended overhangs; together these geometrical choices mean fewer rework cycles and better first-pass accuracy on turned components.

ISO compatibility and operational benefits for workshop efficiency

As an ISO turning insert, the SCMT form offers broad holder compatibility provided size, thickness and clamping style match; this simplifies stocking and toolholder selection across mixed fleets. The tougher grade and predictable chip control lower insert consumption in unstable cuts, improving cost per part. In practice, the insert fits into a system: an ISO insert, a matching external holder or boring bar, and the appropriate clamp and screw. This modular approach supports quick index changes and efficient tool management in batch and job-shop scenarios.

FAQ

What materials is this insert best suited for? This insert is optimised for stainless steels; the AH6235 PVD-coated grade gives improved toughness for interrupted cuts and materials prone to work-hardening.

How does the insert achieve better edge stability in interrupted cuts? The AH6235 grade combined with a 0.4 mm corner radius and a robust single-sided chipbreaker reduces chipping risk and maintains a stable cutting edge during interrupted turning with the SCMT 120404 geometry.

Will this insert fit existing ISO holders? Compatibility depends on form, relief angle, tolerance and thickness; the SCMT form and ISO designation mean it is compatible with ISO-standard holders that accept 12 mm square inserts and a 4.76 mm thickness.

Can the insert be used for internal turning? Yes, the geometry and chip control of this SCMT insert make it suitable for both external and internal turning operations where the holder and bore access permit.

What is the product identification for ordering? Order using the manufacturer article number 6903474 or the manufacturer SKU TUN6903474 to ensure delivery of the genuine SCMT120404 AH6235 Tungaloy turning insert.
