DCMT 11T304 AH6225 Tungaloy insert — ISO rhombic turning insert for stainless steel, PVD-coated, 0.4 mm radius

A DCMT 11T304 AH6225 rhombic ISO turning insert engineered for external and internal turning of stainless steels, combining a sharp cutting edge with stable wear behaviour for medium machining conditions

• ISO rhombic form for standard holders
• PVD-coated carbide AH6225
• 0.4 mm corner radius for fine finishes
• Cylindrical hole with 40°–60° countersink

Consistent results for stainless steel turning

The PVD-coated AH6225 grade is formulated as a universal solution for stainless steel machining, balancing a sharp cutting edge with the toughness needed for variable conditions. This composition reduces flank wear and supports a steady surface quality during medium-duty turning, translating into fewer insert changes and more predictable cycle times. For shops processing mixed stainless components, the insert’s balanced microgeometry helps maintain dimensional accuracy while lowering the risk of built-up edge formation.

Easy integration with ISO toolholder systems

The rhombic ISO geometry and standard size simplify mechanical compatibility: form, clearance, tolerance class, fastening, size and thickness determine holder fit. The insert’s rhombic shape, 7° clearance and 0.4 mm radius allow straightforward seating in common external holders and boring bars, shortening setup times and reducing positioning errors. Clear guidance on tolerance and clamping interfaces means the turning package—insert, holder, shim and screw—can be specified with confidence for repeatable setups.

Improved chip control and machining economy

Equipped with a single-sided chipbreaker, the insert promotes reliable chip formation when matched to workpiece material and cutting conditions. Stable chip shape reduces interruptions and safeguards the cutting edge, which contributes to overall economical machining by lowering scrap and tool-change frequency. Selecting the correct chipbreaker and cutting data for the operation will maximise machining efficiency and improve throughput on medium-duty stainless turning tasks.

Workshop handling, clamping and practical notes

The insert features a cylindrical hole with a one-sided countersink (40°–60°) to ensure secure clamping and precise seating; plate thickness 3.97 mm and size 11 mm offer a rigid contact area that supports moderate cutting forces. The ISO designation DCMT11T304 and the compact corner radius of 0.4 mm are suited to fine finishing and profile work where edge integrity is important.

FAQ

What materials is this insert suited for? The AH6225 grade is formulated primarily for stainless steel machining; the DCMT 11T304 insert performs well in a range of austenitic and ferritic stainless materials when matched with appropriate cutting data.

Which toolholders are compatible with this ISO insert? Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic ISO geometry of the DCMT 11T304 matches standard rhombic external holders and boring bars designed for ISO turning inserts.

How does the 0.4 mm corner radius affect machining results? A 0.4 mm radius provides a balance between edge strength and fine surface finish, making it suitable for finishing passes and profile work where good surface integrity is required without excessive cutting forces.

What advantage does the PVD coating bring? The PVD-coated AH6225 grade enhances wear resistance and edge life under the elevated temperatures and adhesion tendencies typical of stainless steel turning, resulting in more consistent component quality.

Can the chipbreaker be used for heavy roughing? The insert is supplied with a single-sided chipbreaker suitable for medium machining; for heavy roughing, selecting a chipbreaker and grade matched to higher stability and greater depths of cut is recommended.
