SDMT 1204AF NS740 milling insert — Tungaloy indexable plate for finishing

A SDMT 1204AF NS740 indexable insert designed for Tungaloy milling systems, intended for finishing to light machining of steel with emphasis on surface quality and dimensional accuracy

• Cermet grade NS740 for fine finishing
• Square 90° form for versatile milling
• Single-sided chipbreaker for controlled chips
• Cylindrical hole with countersink for secure clamping

Achieve consistent fine surfaces and dimensional control

The NS740 grade is a cermet cutting material optimised for the final passes on steel where surface quality and dimensional accuracy are decisive. Its composition promotes even wear and long contact life under finishing conditions, reducing the need for secondary grinding or rework. Specified relief and geometry maintain stable edge contact, so the result is reproducible part finish and predictable tool change intervals.

Designed for secure clamping and straightforward integration

A square plate form with a cylindrical hole and a one-sided countersink (40°–60°) provides reliable mechanical clamping in compatible milling bodies. The insert’s 4.76 mm thickness and 15° relief must match the pocket and clamping screw geometry of the cutter body to ensure correct seating and torque transfer. Where the insert family aligns with the cutter, setup time is reduced and repeatability of tool location is improved.

Boost productivity in finishing and light machining operations

When applied to facing, shoulder, slot or contour milling operations, this indexable plate supports higher process stability and constant surface results. The single-sided chipbreaker controls evacuation on finishing depths, enabling steady material removal and lowering the incidence of built-up edge. The combination of cermet grade and plate geometry helps to balance productivity with the need for high-quality surface output.

Practical handling and application guidance for workshop use

Manufactured from a carbide substrate with the NS740 cermet cutting grade, the insert is supplied in the SDMT 1204AF geometry with a corner radius of 0 mm for square forms. Correct selection of the matching milling body and clamping screw is essential; the seat, plate geometry and cutter body must be technically compatible to avoid misfit. For best results, follow the cutter manufacturer’s torque and seat-cleaning recommendations before assembly.

FAQ

What applications suit this insert best?
The SDMT 1204AF NS740 insert is intended for finishing to light machining in milling tasks such as facing, shoulder, slot and contour milling where surface finish and dimensional control are priorities.

Is this insert compatible with non-Tungaloy milling bodies?
Compatibility depends on pocket geometry and clamping method; the SDMT 1204AF requires a matching seat and clamping configuration. Use Tungaloy-compatible bodies or confirm technical conformity before assembly.

Which materials can be machined with this grade?
The NS740 cermet grade is optimised for steel finishing, offering uniform wear and improved surface outcomes when used under suitable cutting parameters.
