WCMT050308 AH140 WCMT trigon indexable insert for drilling – Tungaloy

WCMT050308 AH140 Tungaloy indexable insert for precision drilling with exchangeable-plate systems, designed to deliver wear-resistant cutting performance in demanding production environments.

• WCMT trigon insert for drilling applications
• PVD-coated carbide AH140 for high wear resistance
• Cylindrical hole with single-sided countersink
• 0.8 mm corner radius and 7° clearance angle

Consistent drilling performance through wear-resistant geometry

The WCMT050308 AH140 Tungaloy indexable insert combines a PVD-coated carbide substrate with a cutting geometry optimised for drilling operations. The AH140 grade provides increased resistance to abrasion and chipping, which translates into longer tool life and fewer interruptions for insert changes. For production lines where hole quality and repeatability matter, this hardened coating and substrate pairing supports stable cutting conditions and reduces the risk of premature edge failure.

Precise seat and fastening geometry for secure assembly

The trigon plate form and the cylindrical hole with a single-sided countersink (40°–60°) ensure reliable clamping in compatible drill bodies. With a 0.8 mm corner radius, 3.18 mm plate thickness and a 7° clearance angle, the insert offers predictable engagement and chip flow during entry and exit. These measurable parameters make it straightforward to match the insert to the correct drill diameter and seat geometry, simplifying tool selection and reducing set-up time on the machine.

Better chip control and process security in drilling applications

Equipped with a single-sided chipbreaker, the insert improves chip formation and evacuation for a broad range of materials encountered in drilling tasks. The combination of edge geometry and the AH140 grade supports process security under variable cutting conditions, reducing the likelihood of breakouts while maintaining a sharp cutting edge. When selecting inserts for indexable drilling, consider the insert geometry in relation to feed and speed to achieve the best balance between surface finish and tool life.

FAQ

What materials is this insert suitable for?
The insert’s AH140 PVD-coated carbide composition is intended for a wide material range where abrasion and chipping resistance are required; material compatibility should be checked against the drilling body and cutting parameters.

How is the insert mounted in a drilling body?
The trigon form with a cylindrical hole and single-sided countersink allows secure clamping with the corresponding screw and seat, matching the drill body designed for ISO 050308 plates.

What chip control can be expected from the insert?
The single-sided chipbreaker promotes controlled chip formation and evacuation, improving process stability in many drilling scenarios.

Is the corner radius suitable for finishing holes?
The 0.8 mm corner radius provides a balance between robustness and achievable surface quality; finer radii yield improved finishes but may reduce edge strength.

Does the insert require a specific drill body series?
Use drill bodies designed for indexable drilling plates with the ISO 050308 seat geometry; verify the plate seat and clamping method before use.
