SDMT 1204AF AH330 Wendeplatten - Tungaloy

The combination of PVD-coated carbide grade AH330, a sharp cutting edge and a robust one-sided chipbreaker provides reliable, wear- and break-resistant performance for milling operations; order this insert through Metav Werkzeuge or consult their specialists for application advice.

SDMT 1204AF AH330 indexable insert for milling by Tungaloy

SDMT1204AF is an indexable insert designed for Tungaloy milling systems, optimised for plan, shoulder, slot, high-feed and contour milling where a sharp edge and process security are required.

PVD-coated carbide AH330
Sharp cutting edge, process-secure
One-sided chipbreaker; cylindrical hole + countersink
Square 12 mm plate, 4.76 mm thickness

High-performance grade for dependable milling productivity

The insert is made from PVD-coated carbide in grade AH330, a combination chosen for wear resistance and reduced risk of edge chipping during interrupted cuts. This material and coating pairing supports consistent cutting performance and longer tool life under typical milling loads. By specifying a grade engineered for both a sharp cutting edge and process security, the component reduces the need for frequent regrinding and minimises unscheduled machine downtime, which contributes directly to improved production efficiency and predictable machining costs.

Geometry that simplifies set-up and stabilises the cut

With a square 12 mm form and 4.76 mm thickness, the insert offers a stable contact area and straightforward indexability, helping to keep set-up times short. The 90° cutting angle and 0 mm corner radius provide a true shoulder capability, while the 15° relief angle allows reliable chip formation and clearance in a variety of milling strategies. The single-sided chipbreaker is configured to control chip flow for the assigned cutting direction, which enhances surface finish and reduces the chance of built-up edge on the tool. These design features serve production needs by combining repeatable accuracy with easy handling on the shop floor.

Secure clamping and adaptable mounting for system compatibility

The insert is supplied with a cylindrical hole and a single-side countersink (40°–60°) to ensure secure seating and clamp engagement in compatible cutter bodies. The system concept comprises the milling body, insert, clamping screw and, if required, a backing plate; all elements must be technically matched for safe operation. This modular approach gives machine shops the flexibility to equip a family of cutters while maintaining a consistent clamping principle. The clear specification of seating and hole style reduces assembly ambiguity and supports reliable repeatability in series production.

Practical benefits for production planning and tool management

Choosing this indexable insert supports predictable tool-change routines and inventory control because of its standardised geometry and Tungaloy system compatibility. The robust AH330 grade is intended for applications where a sharp edge and process reliability are jointly required, making it suitable for mixed-production environments that demand both surface quality and tool longevity. Where tool performance data is compared, the combination of coating, carbide substrate and chip control typically delivers a favourable balance between cutting life and part quality, aiding in decisions about tooling strategies and cost-per-part evaluations.

FAQ

Which milling operations are suitable for this insert?
The insert is intended for plan, shoulder, slot, high-feed and contour milling depending on the assigned tool family and cutter body.

What is the carbide grade and coating?
The SDMT1204AF is supplied in PVD-coated carbide grade AH330, designed for wear resistance and reduced edge chipping during milling.

How must the insert be mounted in the cutter body?
The indexable insert features a cylindrical hole with a single-side countersink (40°–60°) and requires a compatible clamping screw and, where applicable, a backing plate; proper seat geometry and clamping torque are essential.

What geometry details affect machining performance?
Key dimensions are a 12 mm square plate, 4.76 mm thickness, 0 mm corner radius, 15° relief angle and a 90° cutting angle; these parameters influence shoulder capability, chip control and surface finish.

Is this insert compatible with non-Tungaloy systems?
The insert is designed for Tungaloy milling systems; interchangeability depends on exact seat geometry and clamping design, so technical matching is required.
