CCMT120412 AH6235 Tungaloy ISO turning insert for turning — PVD-coated carbide, 1.2 mm radius

A CCMT120412 AH6235 Tungaloy insert designed for ISO-compliant external and internal turning, optimised for stainless steel and demanding interrupted-cut applications

PVD-coated AH6235 grade for stainless steel ISO CCMT120412 rhombic insert, 7° relief 1.2 mm corner radius for robust cutting edge Cylindrical hole with single-sided countersink 40°–60°

High-performance cutting for stainless steel turning

The combination of a PVD-coated surface and a tough carbide substrate provides a balance between wear resistance and edge toughness, making this grade particularly suitable for stainless steel and operations with elevated breakout risk. The selected coating and substrate chemistry reduce built-up edge and improve flank wear behaviour during interrupted cuts, which translates into more consistent component quality and longer periods between indexings. This results in a measurable increase in process stability for batch production and high-mix environments where predictable tool life is critical.

Predictable clamping and ISO compatibility for uninterrupted workflow

As an ISO-designated CCMT insert, the geometry and tolerances are matched to standard external holders; the rhombic shape with an included angle of 80°, a 7° relief angle and a plate thickness of 4.76 mm ensure repeatable seating and secure clamping. The insert’s cylindrical hole with single-sided countersink (40°–60°) supports stable fastening and simple replacement with standard screws and underplates. These features reduce setup time and contribute to reproducible cutting conditions, which supports higher machine uptime and easier tool management across multiple turning centres.

Productive cutting and lower process risk through geometry and chip control

The one-sided chipbreaker and a 1.2 mm corner radius create a robust cutting edge that tolerates interrupted engagement while promoting predictable chip formation. The geometry suits both external and internal turning tasks where controlled chip evacuation and edge strength are essential. In practice, this means fewer unexpected edge failures and improved surface finish on demanding materials. The insert integrates into a conventional system build-up — insert, compatible holder or boring bar, shim and screw — enabling straightforward stockkeeping and replacement routines that support efficient workshop logistics.

FAQ

What materials is this insert best suited for? This insert is optimised for stainless steel applications; the AH6235 grade and PVD coating improve performance in materials prone to work hardening.

Is the insert compatible with standard CCMT holders? Yes, the ISO CCMT120412 geometry and tolerances are intended for compatibility with standard external holders and boring bars designed for CCMT inserts.

What does the one-sided chipbreaker provide? The one-sided chipbreaker promotes controlled chip formation in turning, reducing the risk of chip tangling and assisting consistent surface finish on interrupted and continuous cuts.

How does the 1.2 mm corner radius affect machining? A 1.2 mm corner radius strengthens the cutting edge, improving resistance to edge chipping and offering a balance between edge life and achievable surface finish.

Which fastening arrangement is required for secure mounting? The insert features a cylindrical hole with a single-sided countersink (40°–60°) and is secured using the matching screw, shim and holder combination for reliable clamping.
