Round Insert Milling Cutter – 40 mm, for RDMT 12T3 indexable inserts by Teknik Makina

The Round Insert Milling Cutter is a compact face milling tool designed for light to medium milling operations using RDMT 12T3 indexable inserts, ideal for workshop and small-batch production where rapid tool changes and consistent chip control are required.

• Ø 40 mm cutting diameter
• Three cutting edges for efficient removal
• Fits RDMT 12T3 indexable inserts
• 16 mm shank for secure mounting

High removal rate with compact geometry

The compact cutter achieves a strong balance between size and performance by combining a 40 mm diameter and three cutting edges, which increases the metal removal rate without demanding excessive spindle power. Using indexable inserts such as RDMT 12T3 allows multiple cutting edges per insert; when one edge is worn, the insert can be rotated to present a fresh edge, reducing tool costs and changeover time. This design suits production environments that prioritise cycle-time reduction and predictable throughput.

Secure clamping and straightforward serviceability

A practical clamping concept simplifies maintenance: the head is secured with a locking screw M3.5 and a Torx screw M3.5x8.5, operated with a T15 Torx key, enabling repeatable torque and safe insert retention. Torx drive engagement minimises cam-out and helps maintain consistent clamping force, which in turn supports stable cutting conditions and longer tool life. Simple, reliable fastenings mean less downtime during insert changes and faster setup for repetitive jobs.

Versatile fit for varied machine set-ups

With a 16 mm shank and a compact overall length of 40 mm, the cutter is suitable for operations where tool overhang must be kept to a minimum. The lightweight construction (approx. 0.235 kg) reduces centrifugal loads at higher speeds and helps maintain balance in high-rev applications on small milling spindles. Although compact, the tool is engineered for repeatable accuracy in small-batch or job-shop environments and integrates easily into standard toolholders and automated change systems.

FAQ

What inserts are compatible with this cutter?
The cutter is designed to accept RDMT 12T3 indexable inserts; using the specified insert form ensures the correct seating and chip control for this tool.

How is the insert secured in the cutter?
Inserts are clamped with a locking screw M3.5 and retained by the Torx fastener M3.5x8.5, tightened using a T15 key to achieve secure and repeatable retention for the T280TM.

Can this cutter be used on small machine spindles?
Yes, the combination of a 16 mm shank and compact overall length 40 mm makes the T280TM suitable for machines with limited tool overhang and smaller spindle capacities.

How many cutting edges does the tool provide before insert rotation is required?
The cutter is built for three cutting edges per revolution; each RDMT 12T3 insert offers multiple usable edges, which can be indexed to extend service life.

Is the T280TM available with replacement screws or spare keys?
Replacement fasteners compatible with the T280TM are standard Torx types; ensure use of the specified M3.5x8.5 Torx screw and T15 key to maintain clamping reliability.
