SDMT 1204PD NS740 Wendeplatten - Tungaloy

Combine the NS740 cermet grade's excellent surface finish with the predictable wear behaviour of a compact square 12 mm, 90° geometry and the secure clamping provided by the cylindric hole with countersink; order the SDMT1204PD directly via Metav Werkzeuge or request application advice from their consultants.

SDMT 1204PD NS740 — Indexable milling insert for milling, Tungaloy

SDMT 1204PD NS740 is an indexable insert designed for Tungaloy milling systems, intended for finishing to light machining of steel with a focus on surface quality and dimensional accuracy

• Cermet grade NS740 for fine finishing
• Square 12 mm size, 90° geometry
• 4.76 mm plate thickness with hole
• 15° relief and single-sided chipbreaker

Higher-quality surface finish with cermet precision

The combination of the NS740 cermet composition and the insert's geometry delivers a noticeable improvement in surface finish and dimensional accuracy during finishing operations. Cermet as a substrate offers a fine-grained cutting edge that maintains form under light to medium cutting forces, which reduces the need for downstream polishing. Where consistent component appearance and repeatable tolerances matter, the cermet grade promotes uniform wear and predictable tool life, contributing to more efficient process planning and less rework.

Secure seating and system compatibility for reliable milling

Designed for Tungaloy milling systems, the insert features a square 12 mm form with a 4.76 mm plate thickness, a cylindrical hole plus a one-sided countersink (40°–60°) and a 15° relief angle to ensure stable clamping and precise seat alignment. The model series requires the insert seat, geometry and milling body to match technically, so correct pocket design and clamping screw selection are essential for achieving the rated performance. The 90° main cutting edge geometry supports common shoulder and face-milling tasks while simplifying toolpath programming.

Consistent chip control and process reliability

A single-sided chipbreaker combined with the cermet grade balances chip formation and evacuation for finishing feeds, helping to avoid surface damage and build-up on the cutting edge. This results in stable metal removal rates and consistent part quality across runs. For manufacturers aiming to increase first-pass yield and reduce inspection overhead, the insert's emphasis on stable wear behaviour and surface integrity supports higher overall process efficiency and lower total manufacturing cost per part.

FAQ

Will this insert fit non-Tungaloy milling bodies?
Compatibility depends on the mating seat and geometry; the SDMT 1204PD NS740 requires a matching pocket and clamping concept, so use only bodies specified for this insert geometry.

For which materials is this grade intended?
The NS740 cermet grade is intended for finishing to light machining of steel, prioritising surface quality and dimensional control in steel components.

How does the hole and countersink affect clamping?
The cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping and correct seating of the SDMT1204PD NS740 insert when used with the appropriate clamping screw and shim.

What benefit does the single-sided chipbreaker provide?
The single-sided chipbreaker improves chip formation and evacuation during finishing feeds, supporting stable cutting conditions and preventing edge build-up on the insert.
