DPMT11T302 11T302 NS9530 Tungaloy indexable insert — finishing for turning

DPMT11T302 is an ISO‑standard rhombic turning insert designed for finishing operations in steel, featuring an 11° relief and a 0.2 mm corner radius.

• ISO rhombic insert DPMT11T302, finishing grade
• NS9530 cermet for high surface finish
• 11° relief and 0.2 mm corner radius
• Cylindrical hole with one‑side countersink

Precision finishing for steel turning with minimal cutting forces

The DPMT11T302 insert is supplied in the uncoated NS9530 cermet grade, engineered specifically as a finishing choice for machining steel. The chemical and micro‑structural characteristics of the cermet produce a sharp cutting edge and inherently low cutting forces, which together reduce workpiece distortion and deliver a high surface finish on continuous cuts and small depths of cut. For workshop planners and turning shops aiming to reduce downstream grinding or polishing, the clear benefit is fewer secondary operations and more parts meeting tolerance on first pass.

Consistent geometry and ISO compatibility for predictable results

Built to ISO dimensions, the insert’s rhombic form and 55° geometry ensure repeatable engagement angles in standard holders. The 11° relief and 0.2 mm corner radius create a defined cutting line that assists in producing even finishes across batches. Standardisation of form, relief, tolerance class, fastening, size and thickness simplifies holder selection and inventory management, enabling a predictable process window and faster set‑up times for turning centres and turret lathes.

Practical mounting and system guidance for secure clamping

The insert includes a cylindrical hole with a one‑side countersink (40°–60°) to match common clamping concepts. Compatibility with a given holder is determined by the insert’s form, free angle, tolerance class, fastening and thickness — the ISO turning insert system allows selection of matching clamping sets, underlay plates and replacement screws to ensure stable fixation. Specifying the matching outer holder and clamping kit reduces vibration and supports the intended finishing application.

Application advice and economic impact for production

As a finishing grade, the insert is best paired with a single‑sided chipbreaker and cutting parameters aimed at continuous chip formation and modest material removal per pass. This approach preserves the sharp edge of the cermet and concentrates the process on surface integrity rather than heavy metal removal. The operational advantage is a consistent part finish and reduced rework, contributing to lower unit processing time and better first‑time quality in serial production.

FAQ

Is this insert suitable for finishing steel components?
Yes. The DPMT11T302 in NS9530 cermet is formulated for finishing steel, providing a sharp edge, low cutting forces and a high surface finish for continuous cuts and small depths of cut.

Can the insert be used in standard ISO holders?
Compatibility is achieved via the ISO form and dimensions; the insert’s form, relief angle, tolerance class, fastening, size and thickness determine the correct holder and clamping set for secure mounting of the DPMT11T302 insert.

Which chipbreaker should be selected for this grade?
A single‑sided chipbreaker is supplied for this type; it is recommended to match the chipbreaker and cutting data to the NS9530 finishing grade to maintain edge sharpness and surface quality.

Does the insert require a coated substrate for durability?
This article is an uncoated cermet grade (NS9530), optimised for finishing tasks where a sharp cutting edge and surface integrity are priorities rather than an additional coating for extreme abrasion resistance.

What information is needed to order the correct matching holder?
Provide the insert designation DPMT11T302, the relief angle (11°), thickness (3.97 mm) and the form (rhombic). These details let Metav Werkzeuge identify compatible external holders and clamping kits.
