SDMT 1204PD AH140 SDMT milling insert – PVD-coated carbide by Tungaloy

SDMT1204PD AH140 is an indexable milling insert engineered for reliable face, shoulder, slot, high-feed and contour milling within compatible Tungaloy milling systems.

• SDMT1204PD geometry for Tungaloy milling systems
• PVD-coated carbide AH140 for wear resistance
• Square 12 mm plate with 90° corner angle
• Cylindrical hole with single-side countersink

Consistent cutting performance that extends tool life

The PVD-coated carbide grade AH140 delivers a wear- and chipping-resistant cutting edge that supports longer, predictable tool life and reduces unplanned tool changes. As an indexable insert with a defined 90° corner angle and a sharp cutting edge, it produces stable results across repetitive operations; this translates to fewer machine stops and a lower cost per component. The coating reduces built-up edge formation and improves surface finish, while the robust substrate maintains edge integrity under moderate interruptions and varying cutting conditions.

Secure clamping and system compatibility for trouble-free machining

Designed with a cylindrical hole and one-sided countersink (40°–60°), the insert enables positive clamping with the matching clamp screw and seat on the cutter body. The plate thickness of 4.76 mm and the 12 mm square size provide mechanical rigidity that helps resist bending moments during heavy engagement. The 15° clearance angle reduces rubbing while the zero corner radius supports sharp profiles; these geometric details matter for secure fixation and repeatable positioning, especially when inserts are rotated or replaced during production.

Versatile application range and improved chip control

Assigned to Tungaloy milling systems, this insert is suitable for a variety of milling tasks—face, shoulder, slot, high-feed and contour milling—depending on the chosen cutter family. The single-sided chipbreaker aids in breaking and directing chips away from the cutting zone, which improves process stability and reduces heat concentration on the cutting edge. Where a sharp edge and process security are required, this grade offers a pragmatic balance between productivity and surface quality, making it well suited to both job-shop operations and series production.

FAQ

What types of milling is this insert suitable for?
The SDMT1204PD AH140 insert is specified for face, shoulder, slot, high-feed and contour milling when used in the appropriate Tungaloy milling body and tool family.

How does the AH140 grade affect performance?
The AH140 PVD-coated carbide grade provides wear and chipping resistance, which increases process security and often extends tool life compared with uncoated grades.

Is the insert compatible with any cutter body?
Compatibility requires a matching plate seat and geometry; the insert seat, geometry and milling body must be technically consistent with the SDMT1204PD form.

What does the hole and countersink design provide?
The cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping with the designated clamp screw and helps maintain repeatable positioning during index changes.

Can the insert produce sharp corners?
Yes, the zero corner radius combined with the 90° corner angle is intended to give a sharp edge, suitable for precise profile work and defined shoulder features.
