DCMT 070204 AH6235 Turning Insert — Tungaloy (rhombic 07, 55° cutting angle)

DCMT070204 AH6235 Tungaloy is an ISO-format indexable turning insert designed for external and internal turning where interrupted cuts or unstable conditions demand a tougher grade and reliable edge control

PVD-coated carbide grade AH6235
Optimised for stainless steel machining
Rhombic 07 form with 55° cutting angle
Cylindrical hole with 40°–60° countersink

Durable grade for challenging stainless applications

The AH6235 PVD coating provides a tougher, more fracture-resistant layer suited to operations with increased risk of chipping. As a cemented carbide substrate with a protective film, this grade maintains edge integrity under variable cutting forces, which reduces unplanned tool changes and rework. The result is a predictable process window when machining stainless steel or other alloyed steels in interrupted turning conditions.

Geometry tuned for stable chip control and surface quality

The rhombic 07 form and 55° cutting angle combine to give a robust cutting edge with good access to shoulders and profiles. The 0.4 mm nose radius balances edge strength with achievable surface finish; the single-sided chipbreaker supports controlled chip formation during both roughing and finishing passes. These geometry choices translate into consistent surface quality and repeatable cycle times on production runs.

Clamping and seat compatibility for secure performance

As an ISO-series insert, fit and functionality depend on matching holder form, clearance, tolerance class, attachment method, size and thickness. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to ensure secure seating in compatible holders and to prevent rotation under load. Proper seat selection extends insert life and stabilises tool behaviour in high-vibration setups.

Practical machining advice for longer tool life

For best results in turning stainless steel and similar materials, combine the insert with a rigid holder and appropriate cutting parameters to avoid thermal work hardening. The PVD-coated AH6235 excels in interrupted cuts; however, optimised feed and moderate cutting speeds will preserve the coating and substrate. Regular inspection of edge condition and replacing inserts before catastrophic failure supports consistent productivity.

Why this insert benefits production workflows

Choosing this indexable insert provides a balance of toughness and wear resistance suited to unpredictable chipbreak and interrupted operations. The ISO format facilitates quick replacement and inventory management while the proven AH6235 grade promotes process reliability and lower scrap rates. For workshops aiming to improve uptime and reproducibility, the combination of geometry and grade is a pragmatic choice.
