SDMT 1204AF AH140 indexable insert for milling — Tungaloy

The SDMT1204AF AH140 is a PVD-coated carbide indexable insert for general milling, designed for face, shoulder, slot, high-feed and contour operations within compatible Tungaloy milling systems.

• PVD-coated carbide grade AH140
• Square 12 mm size, 4.76 mm thickness
• 15° relief angle, 90° included angle
• Cylindrical hole with 40°–60° countersink

Durable cutting edges that extend tool life

The PVD-coated hardmetal composition in AH140 delivers enhanced wear and chipping resistance, resulting in longer cutting-edge life under intermittent and continuous cutting conditions. This PVD coating reduces adhesion at the rake face and supports higher cutting speeds where applicable, which translates into fewer insert changes and more consistent cycle times. For production environments the result is measurable: improved uptime and reduced handling frequency per batch.

Secure seating and predictable clamping for process stability

Designed as a square, 12 mm insert with a cylindrical hole and single-side countersink, the geometry ensures positive mechanical location and secure clamping in matched Tungaloy cutter bodies. The listed seat geometry and insert thickness of 4.76 mm combined with a 15° relief angle and 90° included angle provide a stable cutting interface that minimises micro-vibration and promotes repeatable component accuracy. Clarifying compatibility at procurement reduces setup time and prevents mismatched assemblies.

Controlled chips and consistent surface quality

The single-sided chipbreaker is engineered for efficient chip formation and evacuation in a variety of feed and depth settings, which supports steady process security and an improved surface finish on machined faces and shoulders. Within the appropriate tool family this insert enables effective machining of grooving and contour passages with fewer interruptions for chip removal. The carbide substrate together with the coating also helps maintain a sharp edge profile for high-quality part appearance.

Operational efficiency through indexability and system approach

As an indexable cutting solution, the insert allows quick indexing to fresh cutting edges and simplified inventory management, reducing machine downtime compared with solid cutters. The insert is part of a complete system comprising the cutter body, insert, clamp screw and shim where required; ensuring correct matching of seat and geometry is essential for optimal performance. This system-oriented approach supports predictable tool life and repeatability across production batches.

FAQ

What materials can be machined with this insert?
The SDMT1204AF AH140 Tungaloy insert is a PVD-coated carbide grade designed for versatile milling; it is suitable for a wide range of materials typically handled by milling cutters, subject to cutting data and tool family selection.

How must the insert be mounted to ensure correct performance?
Correct mounting requires a matching Tungaloy cutter body with the appropriate insert seat and clamp screw; the geometry and seat must be technically compatible to achieve the expected clamping security and cutting stability for the SDMT1204AF AH140.

Is the SDMT1204AF AH140 available with different corner radii?
This SKU is supplied with a corner radius of 0 mm as specified; other insert variants with different radii may be available under different designations within the Tungaloy product range.

What role does the AH140 grade play in machining?
The AH140 grade provides wear and fracture resistance with a sharp initial cutting edge, supporting process security and consistent edge life in milling operations where a fine, reliable edge is required.

Can the insert be used for high-feed milling applications?
Yes; depending on the assigned tool family and cutter body, the insert form and chipbreaker enable high-feed and specialized milling strategies as part of a matched Tungaloy milling system.
