SDMT 1204PD AH330 Wendeplatten - Tungaloy

The combination of a PVD-coated AH330 grade and a robust carbide substrate ensures high wear resistance and reliable chip control for industrial milling cycles; matching the plate seat, geometry and cutter body preserves process stability. Order availability and technical clarification are possible via Metav Werkzeuge for seamless integration into production workflows.

SDMT 1204PD AH330 – SDMT insert for milling (Tungaloy)

The SDMT1204PD AH330 is a PVD-coated carbide indexable insert designed for industrial face, shoulder and slot milling with emphasis on a sharp cutting edge and consistent process security.

• PVD-coated carbide AH330 grade
• Square plate 12 mm, thickness 4.76 mm
• Compatible with Tungaloy milling systems
• Single-sided chipbreaker, 90° cutting angle

Increased tool life through optimised coating and substrate

The combination of a PVD-coated surface and a wear-resistant carbide substrate in the AH330 grade reduces flank and crater wear under demanding cyclic loads. This geometry-and-coating pairing promotes stable cutting-edge retention, which translates into fewer insert changes and longer uninterrupted production runs. The result is measurable process reliability and reduced tool-management overhead in batch and continuous machining environments.

Precise fit and compact geometry for repeatable results

A square plate with a nominal size of 12 mm and a thickness of 4.76 mm delivers a compact profile suited to confined pockets and multi-axis cutters. The insert's 90° cutting angle and 15° clearance ensure predictable engagement angles for face and shoulder operations, while a corner radius of 0 mm provides the sharpness required for fine contouring and slotting. Correct matching of the plate seat, the cutter body and the clamping screw is essential for repeatable accuracy and is part of the Tungaloy system philosophy.

Versatile milling applications and effective chip control

Designed for a wide range of milling tasks — from face milling and shoulder milling to slot and high-feed operations — the insert features a single-sided chipbreaker that supports consistent chip formation and evacuation. The cylindrical hole with a one-sided countersink (40°–60°) secures the insert in the pocket while allowing the necessary clamping torque. This chip control strategy reduces edge chipping and helps maintain surface finish quality during interrupted cuts and varying feed rates.

Installation compatibility and system-level benefits

The insert is intended for use only in compatible Tungaloy milling bodies where plate seat, geometry and cutter design match the insert specification. The system comprises the milling body, indexable insert, clamping screw and, where required, a backing plate to achieve the correct seating. When integrated correctly, the design offers predictable tool life, reduced setup time and simpler inventory management thanks to standardised insert indexing and repeatable mechanical clamping.

FAQ

What materials are suitable for these inserts?
The SDMT1204PD AH330 insert is intended for a broad range of milling tasks where a sharp cutting edge and process security are required; the AH330 coating offers enhanced wear and chipping resistance for demanding operations.

How does the chipbreaker affect performance?
The single-sided chipbreaker on the SDMT1204PD promotes controlled chip formation and evacuation, reducing the risk of edge damage during interrupted cuts and improving surface quality.

Is the insert compatible with non-Tungaloy cutter bodies?
The insert requires a cutter body whose seat, geometry and clamping arrangement match the SDMT1204PD specifications; incorrect seat geometry may compromise stability and is not recommended.

Which operations are typical for this insert?
Typical uses include face milling, shoulder milling, slotting and high-feed contour passes, depending on the assigned cutter family and machining parameters.

What is the significance of the 90° cutting angle and 15° clearance?
A 90° cutting angle provides robust engagement for shoulder and face milling, while the 15° clearance helps to reduce rubbing and improves tool life under varying depths of cut.
