DPMT 070208 NS9530 indexable insert for turning — Tungaloy (0.8 mm radius, uncoated cermet)

DPMT 070208 NS9530 is an ISO rhombic indexable insert designed for precision finishing in turning, offering a sharp cutting edge and optimised chip control for continuous cuts in steel

• ISO rhombic shape, size 07
• Sharp cermet grade NS9530
• 0.8 mm corner radius for fine finishing
• Cylindrical hole with 40°–60° countersink

Better surface quality with lower cutting effort

The uncoated NS9530 cermet substrate is engineered as a finishing grade for steel, providing a consistently sharp cutting edge that reduces cutting forces and improves surface integrity. This combination supports stable, continuous machining where small depths of cut are required, translating into fewer secondary operations and a higher first-pass yield. The material choice of uncoated cermet also minimises built-up edge risk at moderate cutting speeds, helping to maintain dimensional accuracy and repeatable part quality.

Seamless integration into ISO tooling systems

Designed to the ISO indexable-insert standard, the geometry and tolerances of the plate ensure compatibility when matched with an appropriate external holder, clamping set and replacement screws. Fit is determined by form, relief angle, tolerance class, fastening method, size and thickness; selecting the correct holder and shim guarantees repeatable seating and stable toolholding. A system-focused setup—insert, holder, shim/clamping set and screws—reduces setup variability and supports predictable process control on CNC lathes.

Geometry and chip control for productive finishing

The rhombic form and 0.8 mm nose radius balance edge strength and form accuracy, delivering fine edge detail without sacrificing toughness. The one-sided chipbreaker directs chips efficiently for finishing cuts, while the insert’s cylindrical hole with one-sided countersink (40°–60°) ensures secure clamping and repeatable orientation. The 11° relief angle and a plate thickness of 2.38 mm contribute to a stable cutting geometry that resists vibration in light finishing passes, supporting consistent surface quality and longer effective edge life.

Recommended use and machining approach

Intended primarily for turning, this insert is optimised for finishing operations in steel where continuous cutting and small feeds are typical. The cemented carbide body provides the rigidity needed for fine-finish tasks, while the NS9530 finishing grade helps achieve high-quality surface finishes with reduced burr formation. For best results, match the insert to a holder suited to small-depth finishing, monitor cutting forces, and choose chipbreaker and grade combinations aligned with workpiece stability to maintain productivity and part integrity.
