RCMT1204EN AH140 Tungaloy milling insert — PVD-coated carbide, with hole, 7° relief

The RCMT1204EN AH140 is a round indexable milling insert for Tungaloy milling systems, engineered for face, shoulder, slot, high-feed and contour milling where a sharp cutting edge and process security are required

• PVD-coated carbide grade AH140
• One-sided chipbreaker for stable chip control
• Round 12 mm insert with 4.76 mm thickness
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for mixed milling tasks

The PVD-coated carbide grade AH140 delivers a balance of sharpness and wear resistance that suits a wide range of milling operations. Insert geometry and grade were selected to maintain a sharp cutting edge while resisting premature wear, which reduces the need for frequent index changes. For production environments that alternate between face, shoulder and contour passes, this combination provides reproducible results and helps maintain cycle-time targets.

Reliable chip control reduces interruptions

Equipped with a one-sided chipbreaker and a cylindrical hole with countersink, the insert promotes predictable chip formation and evacuation. Stable chip control reduces the risk of built-up edge and workpiece damage, lowering machine downtime and tool handling. The integrated seating and hole style ensure secure clamping in compatible tool bodies and contribute to repeatable machining under varying cutting conditions.

Simple compatibility with Tungaloy milling systems

Designed for use in matching Tungaloy tool holders, the round shape and standard ISO designation 1204EN make mechanical integration straightforward when seat and geometry correspond. The insert’s relief angle of 7° supports efficient engagement and clearance in common pocket designs, while the standard size simplifies tool inventory management. Clear specification of seat geometry and tool family alignment avoids misfits and streamlines tool changeovers.

Durable performance that supports productivity

The combination of the chosen carbide grade and PVD treatment enhances surface hardness and resistance to micro-chipping, resulting in long tool life and fewer index changes over a production shift. For shops aiming to improve overall equipment effectiveness, this wear resistance contributes directly to higher throughput and reduced tooling costs per part when used in appropriate cutting windows and with verified process parameters.

FAQ

What materials is this insert suited for?
The RCMT1204EN AH140 insert is a PVD-coated carbide product designed for general milling; its wear properties make it suitable for a broad range of materials depending on cutting data and tool body selection.

How does the chipbreaker affect performance?
The one-sided chipbreaker on the RCMT1204EN AH140 promotes controlled chip formation and evacuation, improving process stability and reducing the likelihood of built-up edge during interrupted cuts.

Is the RCMT1204EN compatible with all Tungaloy tool bodies?
Compatibility requires that insert seat, geometry and clamping match the tool body; the RCMT1204EN follows the ISO 1204EN form and fits Tungaloy milling systems that accept this designation.

What is the relief angle and why does it matter?
The relief angle is 7°, providing clearance during engagement to reduce rubbing and support efficient material removal in typical pocket designs.
