SDMT 1204PD AH330 Tungaloy indexable insert for milling

The SDMT1204PD AH330 Tungaloy indexable insert is a square carbide insert designed for robust performance in a wide range of milling operations, providing wear resistance and consistent cutting edge stability.

• PVD-coated carbide AH330
• Sharp cutting edge for process security
• Square 12 mm insert, 4.76 mm thickness
• Cylindrical hole with countersink 40°–60°

Greater process reliability for consistent production

The combination of a PVD-coated surface and the AH330 carbide grade gives this insert excellent wear resistance, which translates into longer intervals between indexings and more predictable tool life. In practice, the coating reduces flank wear and helps preserve a sharp cutting edge, so machining tolerances remain stable over longer runs. For manufacturers aiming to reduce variance in batch production, this means fewer tool changes, less scrap and a smoother production flow.

Geometry and fit engineered for secure clamping

A technically matched insert seat, geometry and milling body are essential for safe operation. The insert features a square 12 mm form with a 4.76 mm thickness and a 0 mm corner radius, allowing precise engagement on flat, shoulder and slot faces. The cylindrical hole with one-sided countersink (40°–60°) ensures a reproducible clamp position and reliable seating against the screw and pocket. These mechanical details reduce micro-movement under cutting loads, improving dimensional repeatability and surface finish while simplifying tool assembly on compatible milling bodies.

Clear application advantages and machining guidance

Designed for general milling tasks — including plan, shoulder, slot, high-feed and contour milling depending on the assigned tool family — the insert supports a variety of steel and alloy applications when paired with a suitable tool body. The sharp cutting geometry favours clean chip separation and stable cutting forces; where vibration control and chip evacuation matter, the one-sided chipbreaker promotes regular chip formation. For users less familiar with indexable tooling: a chipbreaker shapes the flow of swarf to avoid entanglement and to protect the insert edge from irregular loading.

Practical handling, indexing and economy

Handling and replacement are straightforward: the centre hole and countersink guide the insert into the correct seat for each indexing action, and the standard square form offers four usable edges per insert where applicable. That multiplicity of edges improves cost-efficiency per cutting edge compared with single-edge tools. Where process security and repeatable edge quality are priorities, this design helps to lower operating costs by extending the effective use of each insert while maintaining surface quality.

FAQ

Which materials can be machined with this insert?
The SDMT1204PD AH330 Tungaloy indexable insert is intended for milling a broad range of materials when used in the correct tool family; the PVD-coated AH330 grade offers good wear resistance across steels and common alloys.

How is the insert fixed in the milling body?
The insert seats on a pocket and is secured by a clamping screw; the cylindrical hole with one-sided countersink ensures correct centring and a reproducible clamp position for secure fixation.

What advantages does the AH330 grade provide?
AH330 combines a PVD coating with a wear- and fracture-resistant carbide substrate to preserve a sharp cutting edge and increase process security during interrupted and continuous milling.

Is this insert suitable for high-feed milling?
Yes; when mounted in a compatible high-feed tool body from the same system family, the geometry and chip control of this insert can be used for high-feed and heavy-duty operations as specified by the tool manufacturer.

How many cutting edges are usable per insert?
The square geometry offers multiple cutting edges; depending on wear and your tool setup, each edge can be indexed to present a fresh cutting profile, improving cost efficiency per edge.
