TNMG 160404 AH6235 — Turning insert, PVD-coated carbide, 60°

TNMG160404 AH6235 is an ISO-format turning insert designed for external and internal turning, with a focus on interrupted cuts and applications where increased breakout risk occurs

• PVD-coated cemented carbide
• Optimised for stainless steel
• Triangular insert, 60° cutting geometry
• Double-sided chipbreaker, with cylindrical hole

Proven toughness for demanding stainless steel work

The AH6235 grade is a PVD-coated cemented carbide formulated to deliver enhanced toughness where material adhesion and built-up edge risk are elevated. This makes the insert particularly suitable for turning operations on stainless steel and for intermittent cutting passes. The tougher substrate reduces chipping under variable cutting forces, which translates into fewer indexings and longer effective tool life — a direct improvement to process uptime and cost-efficiency. The coating enables stable performance at typical turning speeds while helping to maintain a consistent cutting edge.

Predictable geometry for repeatable surface quality

An ISO-standard triangular geometry with a 60° included angle and a 0.4 mm corner radius provides predictable cutting behaviour across series production. The listed geometry ensures stable tool engagement during radial passes and helps control the resulting surface finish. The listed 0° clearance supports neutral cutting entry angles, making this insert versatile for both light finishing and heavier, interrupted cuts. The ISO conformity simplifies holder selection and reduces the effort required to validate new tool setups.

Secure mounting and straightforward compatibility

The insert is supplied with a cylindrical hole, enabling reliable centring and clamping in compatible ISO holders and boring bars. Compatibility to the chosen holder is governed by form, free clearance angle, tolerance class, fastening method, size and thickness; matching these parameters reduces assembly time and avoids insecure seating that can cause vibration or premature wear. The double-sided design doubles the number of usable cutting edges per insert, lowering tooling consumption and simplifying inventory management.

Chip control and application-focused performance

A double-sided chipbreaker geometry supports consistent chip formation across a range of feeds and depths, easing chip evacuation and reducing the risk of surface damage during interrupted operations. When paired with the AH6235 grade, the chipformer assists in taming the typically sticky behaviour of stainless steel, improving both productivity and repeatable dimensional accuracy. For shops seeking a balance between robustness and surface quality, this insert provides a clear technical advantage in many turning applications.
