RCMT 1204M0 NS9530 — Indexable insert for turning | Tungaloy

RCMT 1204M0 NS9530 is a round indexable insert designed for finishing operations in turning, optimised for continuous cuts and small depths of cut within the TurnTenFeed system.

Uncoated cermet grade NS9530
Sharp cutting edge for superior surface finish
Optimised for continuous cuts and small depths
Round RCMT insert with 7° clearance

Delivering finer surfaces with lower cutting forces

The combination of an uncoated cermet grade and a finely honed cutting geometry reduces cutting forces while promoting stable chip formation, which directly improves surface quality on steel workpieces. For production environments where repeatable finish and reduced secondary operations matter, the low-force behaviour of this insert shortens cycle times and lowers machine load. The NS9530 grade is formulated for finishing, so the result is fewer reworks and a more predictable process window.

Precision finishing in continuous and small-step turning

Designed for continuous cutting and modest depths of cut, this round RCMT insert provides consistent contact angles and predictable flank wear. The 7° clearance reduces rubbing and heat build-up, supporting longer effective tool life under stable clamping conditions. In practice, the geometry and single-sided chipbreaker mitigate unwanted vibrations, making the insert a reliable choice for fine-turning passes where dimensional accuracy and surface integrity are priorities.

System benefits and workshop integration

As a member of the TurnTenFeed model series, the insert integrates with a range of holders and spare parts to create a productive high-feed turning solution. The round RCMT form is forgiving in set-up and aids quick index changes, while the cylindrical hole with one-sided countersink ensures secure location and repeatability. The insert is suited to standard toolholding concepts and supports an efficient workflow when paired with appropriately rated holders.

FAQ

Which materials is this insert best suited to machine?
The RCMT 1204M0 NS9530 insert is optimised for finishing on steel; the NS9530 cermet grade is formulated to deliver low cutting forces and high surface quality on continuous cuts.

Can the insert be used for high-feed roughing?
Although the TurnTenFeed series targets high-feed strategies, the NS9530 grade and the RCMT round form are specified for finishing and small depths of cut rather than primary roughing passes.

What is the function of the cylindrical hole and countersink?
The cylindrical hole with a one-sided countersink (40°–60°) secures the insert reliably in the seat, ensuring repeatable positioning and stable clamping during turning.

How does the 7° clearance affect performance?
A 7° clearance reduces flank contact and rubbing, which lowers heat generation and supports better surface finish and consistent tool life when used under stable fixturing.

Is this insert compatible with existing TurnTenFeed holders?
Yes, the RCMT1204M0 is part of the TurnTenFeed family and is intended to work with compatible holders and system components designed for that series.
