SDGT 1204AF AH330 indexable insert for milling — Tungaloy

SDGT1204AF AH330 is an indexable milling insert designed for Tungaloy milling systems and suited to planar, shoulder, slot, high-feed and contour milling.

• PVD-coated carbide grade AH330
• Square 12 mm insert, 4.76 mm thick
• 90° cutting angle, 15° relief
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance through a wear-resistant grade

The PVD-coated AH330 grade is a cemented carbide formulation developed for milling where a sharp cutting edge and high process security are required. The coating improves resistance to abrasive wear while the substrate maintains edge strength to reduce the risk of chipping under interrupted cuts. As an indexable insert, the component is intended for rapid replacement, which helps to shorten downtime and maintain consistent part quality across production batches.

Secure seating and reliable clamping for repeatability

A cylindrical centre hole with a one-sided countersink (40°–60°) allows positive location in common screw-clamp systems and contributes to secure clamping during heavy engagement. This combination reduces micro-movements between insert and cutter body, resulting in improved surface finish and reduced vibration. The standardised seat geometry means the insert will deliver predictable torque behaviour and straightforward re‑indexing when a new cutting edge is required.

Geometry tailored to accurate profile and shoulder milling

The insert’s 90° cutting angle and 15° relief produce true shoulders and defined profiles with minimal secondary cutting. A corner radius of 0 mm ensures a keen edge for fine detail and tight-radius features, while the one-sided chipbreaker assists with chip control in the intended feed range. The specified geometry suits operations where dimensional accuracy and edge definition are priorities.

Application versatility and system compatibility

Designed for use in Tungaloy milling systems, the SDGT1204AF AH330 insert forms part of a system comprising cutter body, indexable insert, clamping screw and optional shim. Typical applications include face milling, shoulder milling, slotting, high-feed and contouring. Matching the insert seat, geometry and cutter body is essential for optimal performance; compatibility with the associated tool family ensures predictable tool life and machining results.

FAQ

What distinguishes the AH330 grade from other carbide grades?
The AH330 grade is a PVD-coated cemented carbide designed for wear and fracture resistance in milling; the SDGT1204AF AH330 insert benefits from this combination to maintain a sharp cutting edge and consistent process security.

Can this insert be used in non-Tungaloy cutter bodies?
The insert is specified for Tungaloy milling systems; while the SDGT1204AF AH330 can physically fit other bodies with matching seat geometry, optimal performance requires matching insert seat, geometry and clamping method.

How does the countersunk hole improve clamping?
The cylindrical hole with a single-side countersink (40°–60°) centres the insert and supports the clamping screw, providing positive location and reducing micro-movement for improved repeatability with the SDGT1204AF AH330 insert.

Which milling operations are particularly suitable for this insert?
The insert is intended for planar (face), shoulder, slot, high-feed and contour milling where a sharp edge and reliable chip control are required, making the SDGT1204AF AH330 appropriate for a broad range of finishing and roughing tasks.
