SCMT09T308 AH6235 — SCMT indexable milling insert for milling, Tungaloy

The SCMT09T308-23 AH6235 is an indexable milling insert engineered for milling tasks that demand resilience in interrupted cuts and reliable edge stability within stainless steel machining.

• PVD-coated grade AH6235 for toughness
• Optimised for stainless steel and interrupted cuts
• Square 09 format with 90° cutting angle
• 0.8 mm corner radius for edge strength

High toughness for interrupted cutting in stainless steels

The PVD-coated AH6235 grade is formulated to provide increased toughness compared with conventional grades. This means the insert resists chipping under fluctuating engagement conditions common in face, shoulder and contour milling. The PVD coating reduces flank wear and improves edge stability, which translates into longer in-service life and fewer index changes. For shops working with stainless steel, the tougher substrate and coating combination helps manage built-up edge and brittle fracture during interrupted cuts, delivering more consistent cycle times and less scrap.

Precise geometry for secure seating and repeatable results

A correctly matched insert seat and clamping arrangement are central to repeatable performance. The square 09 format and 90° cutting angle ensure a predictable cutting geometry ideal for shoulders and face milling, while the with-hole design with cylindrical hole plus single-side countersink (40°–60°) supports secure clamping and accurate axial positioning. When the insert, toolholder and clamping screw are technically compatible, vibration is minimised and surface finish remains steady across batches.

Effective chip control and targeted application scope

The integrated chipbreaker (type 23) is optimised to break chips reliably in moderate to heavy engagement conditions, reducing the risk of re-cut and improving evacuation. This chip control, combined with the insert’s toughness, makes the grade suitable for applications such as planing, shoulder milling, slotting where interrupted cuts occur, and high-feed operations depending on the host cutter family. Explaining “chipbreaker”: it is a micro-geometry that shapes chip flow so swarf clears safely rather than entangling, which increases process stability and operator safety.

Practical handling to maintain production flow

Installation requires that the insert seat, geometry and the milling body match exactly; the system typically comprises the milling body, indexable insert, clamping screw and, where required, a backing shim. Correct seating and consistent clamping pressure are essential to preserve the 0.8 mm corner integrity and the PVD layer. For production environments this reduces downtime for regrinds and minimises unexpected insert failure. For complex stacks or uncertain interfaces, consult technical documentation or request advice to ensure optimal tool life and component compatibility.

FAQ

Which materials is this insert suited for?
The SCMT09T308-23 AH6235 insert is optimised for stainless steel and other materials that demand increased toughness, particularly where interrupted cuts or increased breakout risk are present.

For which milling operations is this grade recommended?
This insert is intended for face, shoulder, slot and high-feed milling operations that benefit from a square 09 insert with a 90° cutting angle and robust chip control.

How must the insert be mounted for safe operation?
The indexable insert requires a compatible Tungaloy milling body, correct seat geometry and a clamping screw; the cylindrical hole with single-side countersink secures axial and radial positioning for dependable clamping.

What does the AH6235 designation mean for performance?
AH6235 denotes a tougher, PVD-coated carbide grade developed to withstand interrupted cutting and reduce edge chipping in demanding stainless steel machining.

Is the SCMT insert compatible with non-Tungaloy toolholders?
Performance depends on the exact match between insert seat geometry and the toolholder. The SCMT09T308-23 is designed for Tungaloy milling systems; using alternative holders requires verification of seat, clamping method and dimensions to ensure safety and repeatable results.
