RDMA 1203TN UX30 – RDMA1203TN UX30 Tungaloy indexable insert for milling by Tungaloy

The RDMA1203TN UX30 Tungaloy indexable insert is a round milling insert engineered for precision milling applications where low cutting forces and controlled chip formation are required

• UX30 grade for sharp cutting edge
• Uncoated carbide for low cutting forces
• 15° relief angle for controlled engagement
• Round 12 mm insert with cylindrical hole

Performance-driven compatibility for productive milling

The RDMA1203TN indexable insert is designed specifically for use in compatible Tungaloy milling systems; the insert form, seating geometry and milling body must be technically matched to ensure correct clamping and cutting behaviour. The combination of a round 12 mm form and a cylindrical hole provides reliable mechanical engagement with a screw clamp, while the moderate 3.18 mm thickness contributes to a balance between rigidity and indexability. For workshop planners and process engineers, this means a straightforward replacement routine and predictable behaviour when the insert is mounted in the appropriate milling body.

Controlled cutting with low forces and consistent chips

The UX30 uncoated carbide grade features a sharp cutting edge tailored for operations where reduction of cutting forces and good chip formation are priorities. Being uncoated, the cutting edge delivers immediate sharpness and reduces the tendency for built-up edge in suitable materials, supporting stable cutting at moderate feeds and depths. In practical terms, this leads to improved surface finish, lower spindle loads and often extended tool life through reduced mechanical stress. The 15° relief angle assists in controlled entry and exit behaviour, beneficial for plan, shoulder and contour milling tasks.

Integration into varied milling tasks and simple logistical handling

This round insert is suitable for a range of milling tasks — from plan milling and shoulder milling to slot, high-feed and contour milling, depending on the assigned tool family and milling body. The geometry supports multi-edge indexing where the toolholder system allows, reducing tool inventory turnover and simplifying logistics. Note that optimal performance depends on correct matching of the insert seat, geometry and the milling body; manufacturers’ mounting specifications should be observed. For procurement teams, the compact size and standardised ISO designation make it easy to harmonise with existing stocks and replace worn inserts without lengthy requalification.
