TNGU120708 AH3225 Tungaloy insert – Triangular milling insert for milling, 60° cutting angle

TNGU120708 AH3225 is a triangular indexable insert developed for milling operations; designed for face, shoulder, slot, high-feed and contour milling when matched to the corresponding cutter body

• PVD-coated AH3225 grade for wear resistance
• Triangular 12 mm size with 60° cutting angle
• 0.8 mm corner radius for secure edge form
• Central hole with countersink 40°–60° for stable clamping

Precision and long edge life for mixed milling tasks

The TNGU120708 insert combines a PVD coating with a tough carbide substrate to balance surface finish and tool life. The AH3225 grade is engineered to be resistant to wear and chipping, which means fewer index changes and more reliable cycle times. For operations that require a sharp cutting edge and consistent performance, this insert delivers improved dimensional stability and reduced rework. The controlled coating layer lowers adhesive wear and helps maintain a defined geometry even under variable cutting conditions.

Improved chip control and consistent surface quality

A double-sided chipbreaker together with a 0.8 mm corner radius helps to control chip formation and reduce vibration during cuts. The chipbreaker geometry supports predictable chip flow, which contributes to a uniform surface finish and reduces the risk of built-up edge. In practice, this leads to fewer quality-related interruptions and more repeatable parts per shift. The insert’s edge form also helps preserve cutting integrity when producing shoulders or contours where edge retention is critical.

Secure seating and straightforward clamping for production stability

The insert’s triangular shape (12 mm size) and central hole with cylindrical bore and double-sided countersink (40°–60°) ensure a secure fit in compatible cutter bodies. A thickness of 7.94 mm and the specified 60° cutting angle provide mechanical support against bending and impact loads. It is essential that the insert seat, geometry and milling body are technically matched; correct assembly ensures optimal contact pressure and stable clamping, reducing the risk of loss of concentricity and premature edge failure.

Process benefits that support productivity and predictability

Selecting a PVD-coated carbide insert with a robust grade such as AH3225 reduces the frequency of tool changes and supports steady production throughput. The insert is suitable for a range of milling tasks—face, shoulder, slot, high-feed and contour milling—when used in the appropriate tool family, so fewer tool variants may be needed on the shop floor. The resulting combination of process security and consistent cutting behaviour can contribute to lower unit costs and improved on-time delivery performance.
