ADMT210408 AH140 ADMT indexable insert for milling – Tungaloy

The ADMT210408 AH140 is an indexable milling insert for Tungaloy systems, designed for face, shoulder, slot, high‑feed and contour milling where a sharp cutting edge and process security are required

• PVD-coated carbide grade AH140
• Parallelogram form with 85° cutting angle
• 0.8 mm corner radius for controlled edge strength
• Cylindrical hole with single-sided countersink (40°–60°)

Longer tool life through optimised coating and grade

The combination of a PVD-coated carbide substrate and the AH140 grade delivers enhanced wear resistance and reduced chipping in interrupted or medium-duty milling cycles. The coating reduces adhesive and abrasive wear on the cutting edge, which in turn extends tool life and reduces changeover frequency. For production environments this translates into greater process reliability and fewer unexpected interruptions, helping to keep cycle times stable.

Geometry engineered for secure engagement and consistent finishing

The parallelogram shape and 85° cutting angle provide a predictable contact geometry with the workpiece, balancing shear conditions and radial engagement. The 0.8 mm corner radius increases edge strength compared with very small radii while still allowing good surface finish; it is particularly effective where a compromise between edge robustness and fine detail is required. The insert’s single‑sided chipbreaker controls chip formation to aid evacuation and avoid built‑up edge, improving repeatability across batches.

System integration, flexibility and application scope

Designed as part of a full milling system, the insert must be matched with the correct insert seat, cutter geometry and clamping components for full performance. The built‑in cylindrical hole with a single‑sided countersink (40°–60°) ensures secure clamping and repeatable seating, which is essential for high‑precision operations. Typical uses include face, shoulder, slot, high‑feed and contour milling depending on the assigned cutter family; the insert therefore offers flexibility across multiple milling tasks while maintaining process security.

FAQ

Which milling operations are suitable for this insert?
The ADMT210408 AH140 insert is intended for face, shoulder, slot, high‑feed and contour milling when used in compatible Tungaloy milling systems.

How does the AH140 grade affect performance?
AH140 is a PVD‑coated carbide grade that emphasises wear resistance and breakage control; the grade supports consistent cutting edges under typical milling loads for the specified applications.

What effect does the 0.8 mm corner radius have on machining results?
A 0.8 mm corner radius increases edge strength and reduces susceptibility to chipping compared with smaller radii, while still permitting a good surface finish when correctly applied.

What type of clamping does the insert require?
The insert features a cylindrical hole with a single‑sided countersink (40°–60°) to provide secure clamping and repeatable seating in the corresponding cutter body.

Can the ADMT210408 AH140 be used in any milling body?
The insert is compatible only with bodies that match the ADMT210408 seat geometry; correct matching of insert seat, geometry and cutter body is essential for safe and repeatable operation.
