SCMT 09T304 AH725 ISO turning insert — PVD-coated carbide for turning (Tungaloy)

The SCMT09T304 AH725 is an ISO-format, square turning insert engineered for external and internal turning, featuring a 0.4 mm corner radius and a 7° clearance angle for secure seating and reliable cutting.

• ISO square insert SCMT 09T304
• PVD-coated carbide grade AH725
• 0.4 mm corner radius for versatile cuts
• 7° clearance angle for secure seating
• Cylindrical hole with single-side countersink

Robust performance across steels for dependable cycle times

The AH725 grade is a PVD-coated carbide formulation optimised for both steel and rostfreier Stahl applications, offering reliable wear resistance where material mixes occur. Owing to the coating and microstructure, the insert supports stable chip formation, reducing unplanned interruptions and improving overall productivity on the shop floor. For operations that demand repeatable results with smaller tool sizes or varying workpiece materials, this grade provides a balanced compromise between toughness and wear resistance.

Secure clamping and geometry that supports process security

Designed as an ISO square insert with a 7° clearance angle, the geometry ensures proper seating and minimal movement under cutting forces. The combination of the cylindrical hole with a single-side countersink (40°–60°) and the standardised shape facilitates straightforward mounting in compatible holders, lowering setup time and the risk of misalignment. This mechanical certainty translates directly into fewer rejects and a steadier production flow.

Precision edge and radius for versatile turning operations

The 0.4 mm corner radius provides a controlled cutting edge that copes well with finishing and light roughing passes, delivering good surface quality while maintaining life expectancy. The insert thickness and square form give dimensional stability during contact, enabling consistent chipbreak performance with the one-sided chipbreaker. Where surface finish and dimensional adherence are priorities, this geometry helps to reduce rework and secondary operations.

Practical compatibility and system considerations

As an ISO-standard turning plate, compatibility with holders is determined by form, clearance, tolerance class, fastening, size and thickness. The insert functions within a system that includes a matching external holder or boring bar, backer/clamping set and replacement screws. When integrating into existing tool inventories, confirm holder match to preserve the engineered seating angle and ensure the best performance from the PVD-coated AH725 grade.
