Shank cutter for RDMT 12T3 indexable inserts — Ø 40 mm, 32 mm shank (Teknik Makina)

A shank cutter designed for heavy-duty milling with RDMT 12T3 indexable inserts, suitable for industrial and jobbing-shop applications

• Compatible with RDMT 12T3 indexable inserts
• Ø 40 mm cutting diameter for aggressive machining
• 32 mm shank for stable toolholding
• 45 mm effective cutting length per shank

Stability and process reliability for demanding milling

The solid 32 mm shank and balanced Ø 40 mm body keep the tool rigid under load, reducing chatter and improving surface finish. This cutter is engineered to transfer cutting forces evenly to the spindle, which increases repeatability when machining batches. The robust design supports higher metal‑removal rates and allows the machine to work at more productive feeds and speeds without sacrificing dimensional stability, delivering a measurable improvement in cycle-time efficiency.

Optimised insert system for consistent chip control

Designed specifically for RDMT 12T3 indexable inserts, the cutter enables quick indexation and repeatable pocket seating. The three cutting edges and a 45 mm cutting length per shank are arranged to provide effective chip thinning and evacuation, which is beneficial when working with a range of materials. Operators gain consistent cutting behaviour with fewer interruptions for insert changes, translating into improved throughput and reduced tooling downtime.

Secure clamping and simple maintenance on the shop floor

Fixing and maintenance are straightforward: the tool is supplied with an M3.5 locking screw and an M3.5×8.5 Torx screw operated with a T15 key, enabling rapid insert changes and secure clamping. The accessible screw geometry shortens service intervals and reduces handling time. For workshops seeking predictable maintenance cycles, the configuration minimises the risk of incorrect fastening and supports safe, repeatable tool life management.

Practical application range and workshop integration

With an overall length of 300 mm and a weight of 1.995 kg, the cutter balances reach and mass for stable machining on horizontal and vertical milling centres. The tool is suitable for medium to heavy roughing passes where the combination of diameter and insert type is advantageous. Specification clarity and the choice of a common insert format help procurement teams standardise tooling across machines, simplifying stock management and reordering procedures.

FAQ

What insert type does this cutter accept?
The cutter is designed for RDMT 12T3 indexable inserts and provides correct pocket seating and reliable indexation for consistent performance.

What is the shank diameter and why does it matter?
The 32 mm shank provides increased rigidity and improved toolholding stability, reducing vibration during heavy cuts when using the Teknik Makina shank cutter (R260TM).

How long is the effective cutting length?
The effective cutting length is 45 mm, allowing deeper axial engagement and longer uninterrupted passes compared with shorter‑lipped tools.

Is the tool suitable for roughing operations?
Yes, the Ø 40 mm diameter combined with three cutting edges makes the cutter well suited to medium and heavy roughing where high metal removal is required.

Which fastening hardware is required for insert changes?
Insert retention uses an M3.5 locking screw and an M3.5×8.5 Torx screw; a T15 Torx key is specified for secure and repeatable fastening.
