SDMT 1204PD AH140 indexable insert for milling — Tungaloy

A SDMT1204PD AH140 Tungaloy insert engineered for precision face, shoulder, slot and high-feed milling in Tungaloy milling systems.

• PVD-coated carbide grade AH140
• Sharp, chipping-resistant cutting edge
• Square 12 mm plate, thickness 4.76 mm
• Cylindrical hole with 40°–60° countersink

Reliable cutting performance for continuous milling

The PVD-coated AH140 grade, combined with a cemented carbide substrate, is designed for wear resistance and reduced edge breakdown under interrupted and continuous cuts. This composition supports a consistently sharp cutting edge and more predictable tool life, which reduces unscheduled tool changes and helps maintain production flow. The coating’s thin, hard layer improves thermal stability and friction behaviour, translating into steadier machining and fewer surface defects.

Secure seating and system compatibility for productivity

The plate’s square 12 mm format, 4.76 mm thickness and cylindrical hole with single-sided countersink (40°–60°) ensure a precise fit in cutters that match Tungaloy specifications; correct seat geometry and clamping are essential for repeatable accuracy. A 15° clearance angle and 90° cutting angle make the insert suitable for shoulder and face milling operations where perpendicular walls and defined step-offs are required. Confirm that the cutter body, plate seat and clamp correspond to the same system standard to guarantee safe assembly and optimal cutting conditions.

Practical benefits and recommended milling applications

The insert suits a range of milling tasks—face, shoulder, slot, high-feed and contour milling—depending on the chosen tool family, and the one-sided chipbreaker geometry supports stable chip formation and process security. Reduced chipping risk from the AH140 grade improves component surface quality while lowering scrap rates. For applications demanding a sharp cutting edge and consistent performance across batches, this indexable insert offers a balance of precision and productivity, especially where predictable tool behaviour is a priority.

FAQ

What milling tasks is this insert suitable for? The SDMT1204PD AH140 Tungaloy insert is suitable for face, shoulder, slot, high-feed and contour milling depending on the assigned tool family.

How does the AH140 grade affect tool life? The AH140 PVD-coated carbide grade improves wear resistance and reduces chipping, which supports longer, more predictable tool life for milling operations.

Does this insert fit any milling cutter? The insert requires a cutter body with a matching plate seat and clamping geometry; the SDMT1204PD must be used in compatible Tungaloy milling systems with the correct seat and clamp.

What does the hole style mean for clamping? The cylindrical hole with a single-sided countersink (40°–60°) provides secure clamping and accurate location in cutter bodies that accept this hole specification.

Can the insert produce perpendicular shoulders? Yes; the 90° cutting angle and 15° clearance make the insert suitable for producing defined perpendicular walls and shoulders when used in an appropriate cutter body.
