RCMT 1204M0 AH905 Turning indexable insert — Tungaloy

The RCMT 1204M0 AH905 is an indexable insert engineered for high-feed, productive rough turning under stable clamping conditions.

• PVD-coated AH905 carbide grade
• For high-feed, productive roughing
• One-sided chipbreaker, 7° relief
• Cylindrical hole with 40°–60° countersink

Efficient cutting for high-feed roughing cycles

The PVD-coated AH905 grade combines wear resistance with fracture toughness to sustain high-feed operations in demanding production environments. The coating improves flank wear behaviour, while the substrate provides a sharp cutting edge that stabilises the process and reduces the need for frequent edge changes. For shops aiming to increase material removal rates, this geometry and grade deliver measurable productivity gains through longer uninterrupted runs and consistent dimensional results.

Secure clamping and predictable chip control

A round insert form with a cylindrical hole and single-side countersink (40°–60°) ensures positive seating and repeatable clamping in compatible holders. The integrated one-sided chipbreaker and 7° relief angle promote controlled chip formation and evacuation during roughing passes, reducing the risk of built-up edge and unexpected tool damage. Clear chip control lowers machine downtime and supports stable surface integrity on the workpiece.

System compatibility and pragmatic tool management

Part of the TurnTenFeed series, the insert is intended for use within a system comprising holders, changeable inserts and spare parts, enabling straightforward replacement and inventory management. The standardised RCMT geometry supports widespread toolholder options, simplifying integration into existing turning stations and allowing quick swaps for uninterrupted production. The insert thickness and diameter are matched to common roughing applications for predictable mechanical support.

Practical handling and application guidance

With a plate thickness of 4.76 mm and a nominal size of 12 mm, the insert balances rigidity and accessibility for flank-heavy roughing operations. The grade is optimised for situations where process security and a reliable cutting edge are required, making it suitable for routine, high-volume turning tasks under stable fixturing. Technical staff will appreciate the familiar indexable format and minimal set-up adjustments when transitioning to this insert family.
