SCMT 09T308 AH6225 indexable insert for milling, Tungaloy

The SCMT 09T308 AH6225 indexable insert is a PVD-coated carbide grade developed for milling operations in stainless steels and for use in compatible Tungaloy milling systems.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• Square insert with 0.8 mm corner radius
• Compatible with Tungaloy milling systems

Consistent cutting performance for stainless steel milling

The PVD-coated AH6225 grade combines a sharp yet stable cutting edge with a formulation tuned for moderate machining and variable conditions. This balance reduces flank wear and maintains surface quality over successive passes, which helps to keep production predictable. The coating improves thermal resistance and adhesion, so the insert sustains cutting performance where temperatures and built-up edge can otherwise shorten tool life. As a result, cycle times are stabilised and rework is minimised, supporting higher throughput and lower scrap rates.

Geometry and clamping that reduce setup time

The square form factor with a 0.8 mm corner radius and a standard 90° orientation is designed to deliver secure seating and repeatable indexing. The insert features a central hole with a cylindrical bore and a single-sided countersink (40°–60°), enabling positive engagement with the cutter body and clamp screw; this arrangement ensures stable holding and reduces micro-movements during heavy cutting. The 7° relief angle provides a compromise between edge strength and clearance, which is especially beneficial when shifting between shoulder, slot and contour operations. Overall, the geometry facilitates straightforward tool assembly and reliable repetition across batches.

System compatibility for predictable production

This insert is intended for use within Tungaloy milling systems where seat, geometry and cutter body must match technically. When mounted in a matching cutter body, the insert contributes to stable chip formation and predictable machining behaviour across face, shoulder, slot, high-feed and contour milling tasks, depending on the chosen tool family. The result is greater process reliability and easier tool management, as tool inventory can be standardised around compatible inserts and bodies, reducing the number of special holders required on the shop floor.

Application guidance for selection and use

Select the AH6225 grade when the machining focus is on stainless steel components at medium cutting parameters or where conditions vary between operations. The insert’s PVD coating and carbide substrate are suited to maintain edge integrity under intermittent cuts and varying feeds. Ensure that the cutter body, clamp screw and seat geometry correspond to the insert form to guarantee proper clamping and performance. If edge life needs extending for specific alloys or higher speeds, consider optimising coolant strategy and feed per tooth rather than changing the basic grade immediately.

FAQ

What materials is this insert suitable for?
The SCMT 09T308 AH6225 insert is formulated primarily for stainless steel machining and is PVD-coated to resist heat and adhesion typical in those materials.

Which tool systems is the insert compatible with?
This indexable insert is designed for use in Tungaloy milling systems; correct performance requires a matching seat, insert geometry and cutter body.

What are the key dimensions to check before ordering?
Verify the insert size (09), corner radius (0.8 mm), plate thickness (3.97 mm) and the hole/countersink style to ensure compatibility with the cutter body.

How does the AH6225 grade affect machining?
AH6225 offers a balance of a sharp, robust cutting edge and thermal resistance thanks to the PVD coating, making it suitable for medium machining of stainless steel under varying conditions.

Is special clamping hardware required?
No special hardware is required beyond the matching clamp screw and seat geometry specified by the milling system; the insert features a cylindrical hole with a single-sided countersink for secure clamping.
