DCMT 11T308 AH6235 Tungaloy indexable insert for turning, 55° rhombic

The DCMT 11T308 AH6235 is an ISO-compatible indexable insert designed for general turning applications, especially where interrupted cuts and stainless steels require a tougher grade.

• PVD-coated carbide AH6235 for stainless steel
• 55° rhombic geometry for precise turning
• 0.8 mm corner radius for reliable edge strength
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for demanding stainless steel work

The PVD-coated AH6235 grade combines a tougher substrate with a wear-resistant surface layer to extend tool life when machining stainless steel and other difficult-to-cut materials. The coating reduces flank wear and helps maintain cutting-edge integrity under interrupted cutting conditions. For workshops aiming to increase uptime, this grade is specified for applications with elevated break-out risk and where chip control and repeatable performance are critical.

Geometry and dimensions that support stable, precise turning

A 55° rhombic geometry provides a versatile approach angle suitable for both external and internal turning operations, enabling reliable surface finish with controlled cutting forces. The 0.8 mm corner radius enhances edge strength, reducing chipping on entry and exit. The insert thickness of 3.97 mm and nominal size 11 contribute to rigidity in the tool assembly, while the cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and repeatable positioning in compatible holders.

Application-focused design for efficient machining and reduced downtime

Specified for turning, the insert performs well in interrupted cuts and in the machining of stainless steels where toughness is prioritised over maximum hardness. Compatibility with a given holder depends on form, clearance angle, tolerance class, fastening type, size and thickness; this ensures that when matched correctly, the system delivers consistent chip formation and improved production stability. Selecting the appropriate chipbreaker and grade to suit material and machining strategy maximises economy and surface quality.

Simple selection guidelines and workshop advantages

When replacing or specifying inserts, match the ISO designation and check holder compatibility for clearance and fastening. The PVD layer and carbide substrate are aimed at balancing wear resistance with fracture toughness, making this insert suited for mixed-batch production where material variability occurs. For shops seeking a pragmatic, application-oriented solution, this insert supports productive machining with fewer unexpected tool failures and predictable change intervals.
