DNGG150408 TH10 DNGG (indexable insert) — Tungaloy — Turning, rhombic 55°, 0.8 mm

DNGG150408 TH10 is an ISO‑standard rhombic indexable insert designed for external and internal turning, offering an uncoated carbide grade that supports low cutting forces and clean surface finishes.

• ISO‑standard DNGG rhombic form
• Uncoated TH10 carbide for low cutting forces
• 55° cutting angle with 0.8 mm corner radius
• Double-sided chipbreaker, with cylindrical hole

Predictable geometry for consistent turning outcomes

The insert’s rhombic form and defined 55° cutting angle deliver a balance between accessibility and rigidity for a wide range of turning tasks. Thanks to the ISO‑standard designation, the geometry is immediately recognisable and comparable across compatible tool holders. The 0.8 mm corner radius provides a controlled cutting edge that reduces vibration and supports a uniform surface finish, while the uncoated TH10 grade of carbide keeps cutting forces low where adhesion-prone materials would otherwise build up on a coated edge. These attributes make the insert a pragmatic choice when process reliability and surface quality are priorities.

Seamless integration into common tool systems

Designed for use with standard DNGG holders and compatible boring bars, this indexable insert features a cylindrical hole for secure clamping and a tolerance profile that matches common holder specifications. Compatibility depends on form, clearance angle, tolerance class, attachment method, size and thickness; the insert’s dimensions and mounting style simplify replacement and re-indexing. The double-sided design extends usable life by allowing indexing to the second cutting edge, reducing downtime and simplifying inventory management for production environments.

Why uncoated TH10 carbide is advantageous for specific jobs

The uncoated TH10 grade excels when machining non‑ferrous alloys and other materials where an uncoated edge promotes lower cutting forces and a cleaner surface. Without a coating layer, edge sharpness is preserved and adhesion-related build-up is less likely, which supports better part finish in sensitive applications. For workshops that prioritise minimal cutting resistance and easy chip flow, an uncoated carbide insert often outperforms coated alternatives in these niche scenarios.

Practical guidance to maximise performance and tool life

Select the chipbreaker and grade according to the workpiece material, machining type and machine stability; the double-sided chipbreaker on this insert assists controlled chip formation under a range of feeds. Ensure the holder matches the DNGG form and accommodates the insert thickness of 4.76 mm to maintain clamping integrity. Stability at the tool tip remains the most influential factor for tool life and surface result, so prefer rigid setups and adjust cutting parameters conservatively when trialling a new insert geometry. Regular inspection of the cutting edge and prompt reindexing when wear appears will keep productivity high.
