Round Insert Milling Head for RDMT 1204 – 40 mm, L40

The Round Insert Milling Head is a compact face milling solution designed for high-productivity machining with RDMT 1204 indexable inserts in constrained tool setups.

• Ø 40 mm cutting diameter
• Compatible with RDMT 1204 indexable inserts
• Four cutting edges for steady material removal
• Compact 40 mm overall length

Increased throughput with a small footprint

A small-diameter cutter that delivers measurable productivity gains: the combination of a 40 mm cutting diameter and 4 cutting edges allows stable chip formation and repeatable surface quality in short overhangs. The tool accepts RDMT 1204 indexable inserts, which are designed for fast, repeatable seating and consistent cutting geometry. For shops migrating from solid-tool strategies, this approach reduces inventory cost by using replaceable inserts, while maintaining the machining characteristics expected from a dedicated face milling head. The compact form factor also reduces tool vibration and contributes to longer insert life.

Fast maintenance and secure assembly to cut downtime

Maintenance is simplified by the use of standard Torx hardware and readily available screws: the head is secured with M3.5x8.5 screws accessed using a Torx T15 key, enabling quick insert replacement and secure clamping during operation. This reliable fastening system lowers the risk of assembly errors and minimises unplanned stops on the shop floor. The head’s modest mass and balanced design support predictable tool behaviour, helping to keep cycle times consistent across repeated production runs.

Designed for tight setups and versatile workshop use

With an overall length of 40 mm and a mounting bore of 16 mm, the cutter suits applications where restricted tool overhang and clearance are critical. The compact dimensions make it appropriate for face milling, light profiling and interrupted cuts where a short projection improves stability. The head integrates easily into existing toolholder systems used for face milling heads and is especially useful for job shops and production environments seeking a compact, indexable solution that fits into established workflows.

FAQ

What inserts are compatible with this milling head?
The milling head accepts RDMT 1204 indexable inserts; these inserts provide repeatable seating and are suited to the cutter’s geometry for stable chip control.

How is the cutter fixed and serviced?
Screws with the specification M3.5x8.5 are used and require a Torx T15 key for assembly and insert changes, allowing quick and secure maintenance.

Which applications suit this 40 mm head best?
The tool is tailored to compact face milling tasks, short overhang operations and situations where a small-diameter cutter improves stability and surface finish.

Is the head suitable for interrupted cuts?
Yes, the combination of 4 cutting edges and secure clamping makes the head capable of handling light interrupted cuts while maintaining insert life.

What toolholders are compatible with the mounting bore?
The head’s 16 mm mounting bore is compatible with standard holders designed for small-diameter face milling heads and short-projection set-ups.
