SCMT 120408 AH725 Tungaloy indexable milling insert (PVD carbide, r0.8)

The SCMT120408 AH725 is an indexable milling insert designed for general milling operations and compatible with Tungaloy milling systems.

• PVD-coated universal grade AH725
• Suited for steel and stainless steels
• Square 12 mm insert, 4.76 mm thick
• Carbide insert with r0.8 corner radius

Consistent cutting performance for varied milling tasks

The combination of a PVD-coated surface and a fracture-resistant carbide substrate delivers consistent edge life and reproducible results in repeated operations. The universal AH725 grade is formulated to maintain a stable cutting edge when faced with mixed materials and fluctuating cutting conditions, which reduces the need for frequent tool changes. With its single-sided chipbreaker, the insert supports controlled chip formation, promoting stable machining routines and lowering the risk of unexpected burrs or tool damage in face, shoulder or contour milling.

Broad application range and reliable material handling

Designed for a wide range of operations — from face and shoulder milling to slotting and high-feed strategies depending on the chosen tool family — this insert supports diverse production demands. The AH725 grade is particularly advantageous where process security is essential, offering reliable performance across steel and stainless steels. The single-sided chip control geometry helps maintain surface quality while reducing cycle-time variability, making the insert suitable for shop floors that require both adaptability and predictable output.

Precise geometry for secure clamping and repeatability

Square form and measured dimensions aid predictable assembly and repeatable tool setup. The insert is a 12 mm square, 4.76 mm thick, with a 90° seating angle and a 7° relief angle; a central hole and a cylindrical bore plus single-sided countersink (40°–60°) ensure reliable clamping force when paired with the correct milling body. The r0.8 corner radius provides a balance between edge strength and achievable surface finish. Important: insert seat, geometry and milling body must be technically matched to secure the expected performance and clamping stability.

Process security and economical machining

A universal, explosion-resistant grade such as AH725 supports long tool life under variable conditions, improving overall equipment effectiveness. Consistent chip control and robust edge retention contribute to lower downtime and fewer scrap parts, translating into measurable production benefits. For operations where dependable repeatability and minimal adjustment time are priorities, this insert gives a robust basis for productive milling cycles while simplifying tool management and inventory choices.

FAQ

What materials is this insert suitable for?
The SCMT120408 AH725 insert is specified for machining steel and stainless steels; the AH725 grade is developed for universal, fracture-resistant performance across these materials.

Which milling operations are supported?
Typical uses include face milling, shoulder milling, slotting, high-feed and contour milling when the insert is combined with the appropriate Tungaloy milling body.

How does the single-sided chipbreaker affect machining?
The single-sided chipbreaker on the SCMT120408 AH725 improves chip control and evacuation, which helps maintain surface quality and reduces the likelihood of re-cutting chips.

What must be checked when fitting the insert?
Ensure the insert seat, geometry and milling body are technically compatible; correct clamping through the central hole and countersink is essential for repeatability and secure fixation.

Can the AH725 grade be used in smaller cutters?
Yes, AH725 is particularly useful for smaller tools and applications requiring high process security due to its fracture-resistant composition.
