SCMT120408 AH6225 indexable milling insert for milling — Tungaloy

The SCMT120408 AH6225 is a square indexable insert designed for Tungaloy milling systems, engineered for medium machining of stainless steel with a sharp, stable cutting edge and secure clamping.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• Square insert with 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

Consistent cutting under variable conditions

The PVD-coated carbide composition of this insert provides a balanced combination of edge sharpness and wear resistance, making it suitable for stainless steel under changing cutting conditions. The AH6225 grade is formulated to deliver a crisp initial edge while retaining stability during interrupted cuts and medium depths of cut. This yields more consistent surface quality and fewer unexpected tool changes, supporting higher overall equipment effectiveness.

Secure clamping for repeatable results

A secure clamping interface is central to repeatability: the square insert features a cylindrical hole with a single-sided countersink (40°–60°) to align reliably with compatible tool bodies. The plate thickness of 4.76 mm, the 12 mm seat size and the 7° clearance angle combine to reduce micro-movements at the cutting edge; the nominal contact angle of 90° supports stable load distribution. Together, these elements reduce vibration and support repeatable component tolerances in serial milling operations.

Versatility across common milling operations

This insert is suitable for a range of milling tasks — from face and shoulder work to slotting, high-feed and contouring — depending on the mating tool family. The 0.8 mm corner radius offers a compromise between strength and surface finish: it raises edge robustness compared with smaller radii while still enabling good workpiece quality. Inventory complexity can be reduced by using a universal grade that covers multiple stainless steel machining scenarios.

Coating and grade explained for pragmatic selection

The AH6225 designation denotes a PVD-coated carbide solution optimised for stainless steel machining at moderate cutting parameters. The coating improves surface hardness and heat resistance, slowing flank wear and preserving the geometry of the sharp cutting edge. For applications requiring higher mechanical toughness or different workpiece materials, selection of an alternative grade or geometry is advisable; however, AH6225 performs well where a balance of sharpness and edge security is required.

FAQ

Which materials is this insert intended for?
The SCMT120408 AH6225 insert is formulated primarily for stainless steel; the AH6225 grade and PVD coating focus on improved wear resistance and edge retention when machining stainless grades.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge strength compared with smaller radii, improving durability in interrupted cuts while still allowing acceptable surface finish for most medium-duty milling tasks.

Will the insert fit any Tungaloy milling body?
The insert will function only when the insert seat, geometry and milling body are technically compatible; matching the seat type and clamping system of the Tungaloy tool family is essential for secure clamping and repeatable performance.

What does the cylindrical hole with countersink provide?
The cylindrical hole with a single-sided countersink (40°–60°) ensures correct axial positioning and supports reliable clamping, which reduces vibration and enhances dimensional consistency during milling.

Is this insert suitable for high-feed milling?
Depending on the specific milling body and cutting parameters, the insert can be used for high-feed operations within the limits of medium machining; final suitability should be confirmed against machine capability and toolholder design.
