SNMG 120404 AH6235 Tungaloy — Turning insert for ISO turning with PVD-coated carbide and 0.4 mm radius

The SNMG120404 AH6235 Tungaloy is an ISO-standard square turning insert, designed for external and internal turning where interrupted cuts or workhardening materials require a tougher grade and stable chip control.

• PVD-coated carbide grade AH6235 for rostfreier Stahl
• 0.4 mm corner radius for versatile turning
• Double-sided chipbreaker with cylindrical hole
• ISO SNMG120404 square insert, 12 mm size

Consistent cutting performance on rostfreier Stahl and difficult jobs

The combination of a PVD-coated surface and the AH6235 grade provides a durable cutting edge optimised for rostfreier Stahl and conditions prone to edge breakout. The coating reduces built-up edge and heat uptake, while the tougher substrate improves resistance to chipping during interrupted engagement. For shops that require reproducible results, this configuration delivers longer intervals between indexings and fewer unplanned tool changes, contributing to a more predictable production rhythm.

Easy integration into ISO tool systems and predictable geometry

As an ISO SNMG120404 square insert with a nominal 90° approach angle and 4.76 mm thickness, the insert mates with standard external holders and boring bars when form, clearance angle, tolerance class, fastening method, size and thickness are matched. The cylindrical hole and double-sided chipbreaker support secure clamping and allow both economical indexings. Clear specification of these parameters simplifies holder selection and reduces set-up time, enabling straightforward replacement within existing tool systems.

Improved productivity through geometry and chip control

The insert’s double-sided chipbreaker and modest 0.4 mm corner radius balance strength and finish: stable chips, controlled breakage and consistent surface quality on both roughing and finishing passes. Because the grade is optimised for interrupted cuts, fewer edge failures occur under unstable cutting conditions, leading to improved uptime and enhanced process reliability. Selecting the appropriate chipbreaker and matching the grade to the workpiece material streamlines cycle times and supports cost-effective machining across a broad range of turning tasks.

FAQ

What materials is this insert best suited for?
The AH6235 grade is formulated for machining rostfreier Stahl and other materials where toughness and resistance to edge breakout are required; the PVD-coated carbide further supports performance under elevated temperatures.

How does the insert mount in a holder?
The SNMG120404 designation, cylindrical hole and standard geometry allow mounting in compatible ISO external holders or boring bars, provided the holder matches form, clearance angle, tolerance and thickness.

How many usable cutting edges are available per insert?
With a double-sided design and square form, several indexing positions are available; typical usage maximises edge life by rotating to fresh corners as wear dictates.

Which features reduce the risk of chipping during interrupted cuts?
The combination of a tougher AH6235 substrate, PVD-coated surface and a modest 0.4 mm corner radius gives enhanced edge stability and improved resistance to chipping in interrupted or unstable cutting conditions.

Is the insert compatible with standard ISO SNMG tool holders?
Yes; the SNMG120404 specification conforms to ISO geometry, but compatibility depends on matching the holder’s tolerance class, fastening and thickness parameters.
