DCMT11T302 AH6225 Carbide Turning Insert for Turning — Tungaloy

DCMT11T302 AH6225 is a rhombic, ISO-standard turning insert designed for medium cutting duties on stainless steels and general turning applications

• PVD-coated AH6225 carbide for stainless steels
• Sharp yet stable cutting edge
• ISO rhombic insert DCMT11T302
• Cylindrical hole with 40°–60° countersink
• 0.2 mm nose radius, 7° relief angle

High-performance coating and substrate for reliable metal removal

The PVD-coated AH6225 grade combines a wear-resistant coating with a tough carbide substrate to deliver a balance of edge sharpness and stability. This results in predictable tool life under varying cutting conditions when machining stainless steel, where built-up edge and heat generation can otherwise compromise component finish. The coating reduces friction and improves cutting-edge protection, which in turn supports higher productivity and fewer interruptions for tool changes.

Precise geometry and ISO conformity for secure holder compatibility

The insert follows the ISO profile for rhombic inserts and is specified as DCMT11T302, ensuring dimensional and tolerance conformity with matching holders. The rhombic form with an included angle of 55°, a 0.2 mm nose radius and a 7° relief angle helps maintain cutting stability while permitting versatile approach angles. The centre cylindrical hole with a single-sided 40°–60° countersink supports reliable clamping and repeatable seating in standard external holders and boring bars.

Practical machining advantages from chip control and edge design

Equipped with a one-sided chipbreaker suited to turning operations, the insert assists controlled chip formation and evacuation, reducing the risk of entanglement and improving surface finish. The moderately sharp but robust edge geometry is tailored for medium-duty cuts and variable conditions; this lowers the likelihood of premature edge failure and keeps cycle times consistent. For production environments, this combination supports process stability and reduces scrap rates through consistent dimensional repeatability.

Guidance for selection, mounting and process optimisation

When choosing an insert, match the chipbreaker and AH6225 grade to the workpiece alloy and cutting parameters: the grade is optimised for stainless steels and similar materials that require a balanced edge. Mounting requires correct seating on a suitable ISO-compatible holder and tightening to the manufacturer’s torque recommendations to ensure repeatable positioning. Regular checks of edge wear and adherence to recommended speeds and feeds will extend service life, while the insert’s design simplifies replacement during shift changes and minimises downtime.
