Round insert face mill for RDMT 1204 indexable inserts — 40 mm, internal coolant (Teknik Makina)

The Round insert face mill for RDMT 1204 indexable inserts is a compact, coolant-fed cutter designed for precise face milling operations where reliable chip control and quick insert changes are essential.

• Ø 40 mm diameter
• Internal coolant feed
• Compatible with RDMT 1204 inserts
• Four cutting edges for balanced cutting

Coolant-assisted cutting for consistent cycle times

The integrated internal coolant feed channels coolant directly to the cutting zone, which lowers cutting temperatures and supports longer tool life. By flushing chips away from the insert pockets the system improves chip evacuation, reducing the risk of recutting and helping to maintain surface finish tolerances in continuous production. With a compact Ø 40 mm body the cutter is particularly suited to tight setups and machines where controlled material removal and repeatability are priorities.

Modular clamping and insert handling to reduce downtime

Compatibility with RDMT 1204 indexable inserts ensures access to a broad range of grades and geometries for different materials. The tool secures inserts with a Torx clamping screw that matches a T15 key and uses M3.5x8.5 Torx screws, enabling quick, standardised insert changes and straightforward maintenance procedures. The four cutting edges arrangement balances forces during cutting, which reduces vibration and improves surface consistency — a direct benefit for batch production and finishing passes.

Compact design and workshop-ready supply chain

Weighing just 0.236 kg and with an overall length of 40 mm, this cutter occupies little spindle space while delivering the rigidity expected in industrial environments. The T139-1TM designation simplifies stock handling and reordering, and the robust build from Teknik Makina supports repeatable setup across multiple workstations. For procurement and integration, Metav offers reliable supply and product advice to help fit the cutter into existing tool programmes without disrupting throughput.

FAQ

What inserts does this cutter accept?
The round insert face mill accepts RDMT 1204 indexable inserts; the configuration is optimised for those round insert geometries to provide secure seating and efficient cutting.

How does the internal coolant benefit machining?
Internal coolant in the cutter directs fluid to the cutting edge to reduce temperature, support chip evacuation and contribute to extended insert life for the T139-1TM tool.

Which Torx key is required for insert changes?
Insert clamping uses a Torx interface compatible with a T15 key and Torx screws sized M3.5x8.5 to ensure standardised, secure tightening.

Is this cutter suitable for compact machine tools?
Yes; the compact Ø 40 mm diameter and 40 mm overall length make it suitable for limited spindle clearance while maintaining the rigidity needed for stable cuts.

How does the four-edge design affect surface finish?
The four cutting edges distribute cutting forces evenly, reducing vibration and supporting consistent surface quality across repeated passes.
