CCMT120404 AH6235 — CCMT ISO turning insert for turning, PVD-coated carbide, 0.4 mm radius (Tungaloy)

CCMT120404 AH6235 is a rhombic ISO-format turning insert designed for external and internal turning, particularly where intermittent cuts or stainless materials increase the risk of edge breakage.

• PVD-coated carbide grade AH6235
• Designed for stainless steel machining
• 0.4 mm nose radius for fine profiles
• Compatible with ISO CCMT holders

Consistent cutting performance for demanding stainless applications

The PVD coating combined with the AH6235 carbide grade delivers a robust cutting edge tailored for tougher-to-machine materials. The composition emphasises ductility and resistance to chipping, helping to maintain a stable cutting process when working with stainless steel or under interrupted cutting conditions. As a result, production runs benefit from fewer tool changes and improved process reliability, which translates into higher uptime and lower per-part tooling cost. The insert’s geometry supports predictable chip flow and a controllable wear pattern, making it suitable for medium-duty finishing and semi-finishing operations.

Stable clamping and controlled chip formation reduce downtime

The rhombic plate form with an 80° approach angle and single-sided chipbreaker is engineered to reduce vibration and limit edge damage during unstable cuts. A cylindrical hole with a single-side countersink (40°–60°) ensures repeatable, secure clamping in compatible holders, while the 7° clearance angle lowers rubbing and heat build-up at the flank. The modest 0.4 mm nose radius permits fine profile definition and improved surface quality without sacrificing the mechanical strength of the cutting edge. These combined characteristics mean less rework and a smoother workflow for batch turning tasks.

Practical guidance for integration and efficient use

With a plate thickness of 4.76 mm and size designation 12, the insert fits standard CCMT pockets when matched for form, tolerance and fastening. Select a suitable holder and backing shim to preserve the correct rake and clearance; the right pairing maximises the grade’s advantages in chip control and edge life. The insert is recommended where interrupted cuts, hard start/stop conditions or high breakout risk occur. For workshops seeking predictable results, the combination of PVD-coated carbide and a single-sided chipbreaker provides a balance between wear resistance and toughness, supporting consistent surface finish and repeatability across production batches.
