DCMT11T304 GT9530 Tungaloy turning insert – 55° rhombic, coated cermet for finishing

The DCMT11T304 GT9530 is a 55° rhombic indexable insert designed for external and internal turning where a fine surface finish and extended tool life under stable conditions are required

• Coated cermet GT9530 grade
• 55° rhombic insert geometry
• 0.4 mm corner radius
• Cylindrical hole with 40°–60° countersink

Delivering consistent finishing and longer tool life

The GT9530 coated cermet composition provides a balance between wear resistance and workpiece surface quality that suits finishing to light universal turning in Stahl. The coating improves adhesion and reduces flank wear, which results in longer cutting life and fewer insert changes. For production environments where cycle stability and predictable tool life matter, this grade supports a reliable process with reduced downtime.

Geometry that matches precision and stability requirements

The rhombic 55° form, paired with a 0.4 mm corner radius and a clearance angle of 7°, gives a favourable compromise between access to detail and edge strength. The insert thickness of 3.97 mm contributes to rigidity in the tool assembly. The insert is supplied with a hole and a cylindrical hole plus one-sided countersink (40°–60°) to ensure secure clamping in compatible holders. Correct holder selection—matching form, relief angle, tolerance class, fastening, size and thickness—ensures the expected cutting behaviour and repeatability in production.

Chip control and application guidance for turning operations

A one-sided chipbreaker is integrated to assist in stable chip formation during external and internal turning. Under steady setup conditions this chipformer helps maintain surface integrity and reduces the risk of built-up edge. Select the GT9530 grade and the chipbreaker geometry to suit material and stability: the grade is optimised for Stahl machining where a fine finish and extended life are priorities. The insert is part of the ISO turning insert family and typically forms a system with an appropriate external holder or boring bar, a backing pad/clamp set and replacement screws.

FAQ

What materials is the GT9530 grade suited for?
The GT9530 coated cermet grade is designed principally for machining Stahl where a fine surface finish and improved tool life are required; it performs best under stable cutting conditions.

Which operations is this insert intended for?
The rhombic DCMT11T304 insert is intended for external and internal turning applications, particularly finishing and light universal turning tasks.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius balances edge strength with the ability to produce a fine surface finish; it reduces the tendency for edge chipping while allowing detailed profile machining.

What does the hole and countersink configuration mean for clamping?
The cylindrical hole with one-sided countersink (40°–60°) ensures secure axial and radial clamping when used with compatible holders and clamping sets, supporting repeatable tool positioning.

Is this insert compatible with standard ISO holders?
Yes, the insert follows ISO designation standards; compatibility depends on matching the holder’s form, relief angle, tolerance class, fastening method, size and thickness to the insert specification.
