SDMT 1204AF AH330 Tungaloy indexable insert for milling

The SDMT1204AF AH330 is an indexable insert for Tungaloy milling systems, engineered for stable shoulder, face and contour milling where a sharp cutting edge and consistent process security are required.

• PVD-coated AH330 carbide for wear resistance
• 90° square insert, 12 mm size
• Cylindrical hole with one-sided countersink
• Single-sided chipbreaker, 15° clearance angle

Durable cutting grade for consistent production output

The AH330 grade is a PVD-coated cemented carbide developed to deliver wear resistance and fracture toughness in milling operations. This combination supports longer tool life and a more predictable tool-change interval, which translates into fewer interruptions on the shop floor and improved overall equipment effectiveness. For manufacturers targeting stable surface quality and repeatable results, the robust grade reduces the likelihood of unexpected edge failures and keeps cycle times constant.

Geometry engineered for accurate shoulder and face milling

A 90° square geometry with a nominal size of 12 mm and a thickness of 4.76 mm provides a stiff cutting edge suitable for shoulder and face operations. The 0 mm corner radius produces a sharp edge for precise corner definition, while the 15° clearance angle lowers rubbing on the relief face and helps maintain cutting performance. The integrated single-sided chipbreaker controls chip flow for the assigned cutting conditions, improving surface finish and reducing heat build-up during longer passes.

System compatibility and practical clamping details

Correct seating and clamping are essential: the insert is intended for use within a Tungaloy milling system comprising a milling body, the indexable insert, a clamp screw and, where required, a shim. The insert features a cylindrical hole with a one-sided countersink (40°–60°) to match many clamping designs and ensure reliable fixation. Typical uses include plan, shoulder, slot, high-feed and contour milling, depending on the selected tool family. The SDMT1204AF AH330 format and chipbreaker arrangement make it a versatile choice for production environments that demand repeatability and straightforward tool management.
