DCMT 11T308 GT9530 ISO turning insert for finishing — Tungaloy

A DCMT11T308 GT9530 indexable insert engineered for fine finishing and prolonged durability in turning applications

Coated cermet grade GT9530 for finishing ISO rhombic form 11 compatible with standard holders 0.8 mm corner radius for superior surface finish Cylinder hole with 40°–60° countersink for secure clamping

Consistent finishing with longer tool life

The GT9530 grade is a coated cermet designed for wear resistance during finishing and light universal turning of steel. Its substrate and coating combination aim to deliver a stable cutting edge and improved surface integrity, meaning fewer in‑process reworks and a more predictable tool life. The 0.8 mm corner radius supports fine edge strength without compromising finish quality, making the insert particularly suited to applications where surface tolerance and visual appearance are important. In practice, this translates to less scrap, reduced machining variation and a more efficient production flow.

Precise fit and mechanical reliability in ISO systems

The insert follows the ISO designation DCMT11T308 and is built to mate with ISO‑standard holders where fit depends on form, relief angle, tolerance class, clamping arrangement, size and thickness. Key geometry data such as the 7° relief angle, 3.97 mm plate thickness and the 55° included angle ensure reliable seating and repeatable chip formation when used with appropriate external holders or boring bars. The presence of a cylindrical hole with a single‑side countersink (40°–60°) facilitates secure clamping and fast index changes, which helps to maintain process stability across repeated tool changes.

Application guidance and practical benefits

Intended primarily for turning of steel in stable setups, the insert comes with a single‑sided chipbreaker that is matched to the GT9530 grade; selection of the chipbreaker and grade should be made according to workpiece material, machining strategy and machine rigidity. The rhombic form provides positive cutting geometry and good access to shoulders and profiles, while the coated cermet composition supports superior surface finish during finishing passes. For operational planning, choose this insert where optimised surface quality and predictable tool life are priorities — it is especially valuable in serial production and tool rooms aiming for consistent part quality.

FAQ

What materials is this insert best suited to machine? The GT9530‑grade coated cermet insert is optimised for machining steel in finishing and light universal turning operations, offering good surface quality and extended wear resistance with stable setups.

How does the DCMT11T308 form affect holder compatibility? Compatibility depends on the insert form, relief angle, tolerance class, clamping method, size and thickness; the DCMT11T308 geometry is ISO‑standard and fits corresponding external and boring tool holders when those parameters match.

What is the purpose of the 0.8 mm corner radius? A 0.8 mm corner radius increases edge strength and supports a superior surface finish on finishing passes while maintaining acceptable cutting forces for the intended applications.

Can the insert be used for roughing operations? The DCMT11T308 GT9530 is engineered for finishing to light universal use; for heavy roughing, a grade and geometry optimised for high material removal rates is recommended.

How is the insert clamped to ensure repeatability? The insert features a cylindrical hole with a single‑side countersink (40°–60°) that enables secure clamping and repeatable seating when paired with the correct clamping set and holder.
