SCMT 120412 AH6235 Turning Insert (PM) — Tungaloy

The SCMT120412-PM AH6235 Tungaloy turning insert is an ISO-standard square insert designed for external and internal turning, delivering controlled chip formation and improved resistance to notch wear in stainless steels and interrupted cuts.

• ISO-compatible SCMT 120412 geometry
• PVD-coated AH6235 for stainless steel
• PM chipbreaker for interrupted cuts
• 7° clearance angle, 1.2 mm corner radius

Consistent chip control for interrupted and stainless steel turning

The combination of the AH6235 cutting grade and a PVD coating provides enhanced toughness and adhesive-wear resistance, which is particularly beneficial when machining stainless steel or mixed-batch workpieces that produce built-up edge. The PM chipbreaker is designed to break chips reliably under varying cutting conditions, reducing manual interventions and protecting the workpiece surface. These material and geometry choices result in fewer unexpected tool changes and a steadier production flow.

ISO conformity and secure clamping for stable processes

Constructed to the ISO SCMT120412 form, the insert offers predictable mounting characteristics: square form, cylindrical hole with one-sided countersink (40°–60°) and standard dimensions ensure compatibility with many holders. The standardised geometry simplifies tool inventory and reduces set-up time, while the defined 7° clearance angle and 90° cutting angle support consistent cutting engagement. Clear mechanical fit and repeatable seating improve process stability and reproducibility across shifts.

Robust edge design that extends cutting life and productivity

The insert is made of cemented carbide and features a 1.2 mm corner radius with a plate thickness of 4.76 mm, giving the cutting edge extra strength where interruptions or variable feeds occur. This geometry helps distribute cutting forces and reduces the risk of premature chipping, allowing higher feed/roughing passes when appropriate. The result is improved throughput and fewer tool indexings, supporting a cost-effective machining strategy without sacrificing surface quality.

FAQ

What materials are best machined with this insert?
The SCMT120412-PM AH6235 insert is optimised for stainless steel and applications with high notch or breakout risk; its AH6235 grade and PVD coating enhance adhesion resistance and toughness.

Is the insert compatible with ISO-standard holders?
Yes, the insert follows the ISO SCMT120412 form, so compatibility depends on holder shape, seating tolerance and fastening; the square form and the cylindrical hole with countersink are standardised for many external and boring holders.

How does the PM chipbreaker affect cutting performance?
The PM chipbreaker promotes short, controlled chips in varying cutting conditions, improving chip evacuation and reducing the risk of entanglement during interrupted cutting or unstable feeds.

Can this insert be used for internal turning as well as external turning?
The design and geometry of the SCMT120412-PM make it suitable for both external and internal turning operations when paired with a compatible holder and appropriate cutting parameters.

What are the mechanical strengths of the insert?
With a 1.2 mm corner radius and 4.76 mm thickness, the insert provides a robust edge for heavy engagement and resistance to chipping under interrupted cuts.
