DPMT11T304 AH6225 DPMT ISO turning insert by Tungaloy

The DPMT11T304 AH6225 is a rhombic ISO turning insert designed for external and internal turning of stainless steels, combining a PVD-coated carbide grade with a single-sided chipbreaker for consistent medium-duty machining.

• PVD-coated carbide AH6225 for stainless steels
• ISO rhombic insert, 11 mm size
• 55° included angle and 0.4 mm corner radius
• Cylindrical hole with 40°–60° countersink

Improved process reliability through a stable cutting edge

The insert delivers a stable cutting edge thanks to the AH6225 PVD coating applied to a wear-resistant carbide substrate. This combination reduces flank wear and supports longer tool life in interrupted and continuous cuts. For workshops aiming to raise first-pass yield and reduce rework, the grade provides a balance between edge sharpness and toughness, making it suitable for medium cutting depths on stainless steels. The single-sided chipbreaker optimises chip control in common shop-floor conditions and eases chip evacuation from the cutting zone.

Easy integration with ISO toolholders for predictable set-up

Designed to ISO dimensions, the insert fits standard holders when form, relief angle, tolerance class, fastening method, size and thickness match. The rhombic geometry and cylindrical hole with single-side countersink simplify clamping and indexability, so changeovers are faster and runout is minimised. Specified dimensions such as 11 mm across flats, 3.97 mm thickness and 11° relief enable precise seating and repeatable positioning, which reduces set-up time and supports consistent part tolerances in serial production.

Practical benefits for daily turning operations

The 0.4 mm corner radius and 55° included angle provide a compromise between strength and surface finish: the edge resists chipping while still producing acceptable surface quality in medium-duty turning. The PVD layer improves resistance to built-up edge on tough alloys, while the substrate retains toughness under intermittent cuts. For job shops and production lines working with mixed batches of stainless-steel components, this insert contributes to predictable cycle times and fewer unscheduled insert changes, increasing overall machining throughput.

FAQ

What materials is this insert suited for?
The DPMT11T304 AH6225 insert is optimised for machining stainless steels, with the PVD-coated carbide grade AH6225 offering balanced wear resistance and edge stability for medium-duty turning.

Can the insert be used in standard ISO holders?
Yes, the ISO dimensions (rhombic form, 11 mm size, 3.97 mm thickness) allow compatibility with standard ISO toolholders when matching form, relief angle and fastening; correct holder selection ensures secure clamping and repeatable performance.

What chip control can be expected from this geometry?
The single-sided chipbreaker delivers consistent chip formation for typical turning operations, aiding chip evacuation and reducing the risk of entanglement during medium cuts.

How does the AH6225 grade perform under interrupted cuts?
AH6225 combines a sharp, wear-resistant PVD coating with a tough carbide substrate, providing improved resistance to chipping during interrupted cuts while maintaining acceptable flank wear behaviour.
