RDMW 1204ZD AH140 indexable milling insert for milling — Tungaloy

RDMW 1204ZD AH140 is an indexable milling insert for Tungaloy milling systems, intended for face, shoulder, slot, high-feed and contour milling where a sharp cutting edge and process reliability are required.

• PVD-coated carbide AH140 for wear resistance
• Round insert Ø12 mm, 4.76 mm thickness
• 15° relief angle for versatile cutting
• Cylindrical hole with 40°–60° countersink

High-performance grade for consistent machining results

The PVD-coated AH140 grade combines a fine-grained carbide substrate with a robust surface layer to deliver improved wear resistance and edge stability during interrupted and continuous milling. This characteristic reduces tool change frequency and supports a predictable process window, which is particularly valuable in production environments requiring repeatable component quality. The result is a measurable improvement in uptime and component consistency without compromising cutting precision.

Geometry and clamping designed for process security

The insert's round form with Ø12 mm diameter and 4.76 mm thickness provides a compact, stable contact area that spreads cutting forces and supports high-feed and contour operations. The 15° relief minimises rubbing while maintaining a sharp cutting action, and the cylindrical hole with one-sided countersink (40°–60°) ensures reliable seating and clamping in the toolholder. As this variant is supplied without a chipbreaker, planning for chip evacuation should be considered in the machining strategy to maintain surface quality and tool life.

System compatibility and recommended applications

This insert is part of a modular milling system and will perform best when the insert seat, geometry and milling body are technically matched. Typical setups include the milling body, the indexable insert, a clamp screw and, where required, a support shim. The grade is optimised for applications that demand a sharp cutting edge and high process security, such as facing, shoulder milling, slotting and high-feed passes. If there is any uncertainty about compatibility or the ideal tool family for a specific task, internal technical advisors can provide tailored recommendations.

FAQ

What applications suit this insert best?
The RDMW 1204ZD AH140 indexable milling insert from Tungaloy is designed for face, shoulder, slot, high-feed and contour milling where a sharp cutting edge and process reliability are priorities.

Is the AH140 grade suitable for interrupted cuts?
Yes, the AH140 PVD-coated carbide grade is formulated to resist wear and chipping, making the RDMW 1204ZD AH140 suitable for many interrupted and continuous milling conditions.

How does the round shape affect performance?
The round insert geometry spreads cutting forces and supports versatile cutting directions; combined with the insert thickness and relief angle, it enhances stability during high-feed and contour milling operations.

What clamping features ensure secure seating?
The insert features a cylindrical hole with a one-sided countersink (40°–60°), providing reliable seating and clamp engagement when paired with the correct milling body and clamp screw.

Is there a chipbreaker on this insert?
This insert is supplied without a chipbreaker; chip control must therefore be managed via cutting parameters, coolant strategy and the chosen toolholder configuration.
