Shank cutter R242TM — indexable milling cutter, Ø 40 mm, 3 cutting edges (Teknik Makina)

A robust shank milling cutter designed for high-production jobs, the Shank cutter R242TM is suited for installations using RDMT 12T3 indexable inserts and engineered for stable, repeatable machining.

• Ø 40 mm cutting diameter
• Compatible with RDMT 12T3 inserts
• 32 mm shank diameter for secure clamping
• 45 mm effective cutting length

Productive indexable milling that reduces cycle time

The R242TM delivers a balanced combination of diameter and cutting geometry that supports efficient material removal with the flexibility of indexable inserts. With a Ø 40 mm cutter body and three cutting edges, this design reduces downtime for edge changes and keeps spindle loads predictable. The use of RDMT-style inserts means tooling costs are controlled through repeatable insert life and straightforward reconditioning, which supports leaner production cycles and a better cost-per-part ratio.

Stable clamping and straightforward maintenance for consistent accuracy

A 32 mm shank provides increased rigidity and improved run-out stability in most machine tool holders, while the 45 mm cutting length offers a practical balance between reach and structural support. The cutter’s fastening hardware — a locking screw M3,5, a Torx screw M3,5x8,5 and a T15 key — ensures fast, secure insert mounting and simplifies service routines. At approximately 0.956 kg, the tool is sufficiently robust for industrial use while remaining easy to handle during tool changeovers.

Flexible application through indexable insert technology

Designed specifically for use with RDMT 12T3 indexable inserts, the R242TM allows quick adaptation to different cut conditions simply by choosing the appropriate insert grade and geometry. This flexibility turns the cutter head into a modular solution for a range of machining tasks where insert-based strategies are preferred, enabling selective investments in carbide grades and coatings without replacing the entire tool body. The result is a future-proof approach to process planning and inventory optimisation.

Supply reliability and workshop partnership with Metav

Sourcing the cutter via Metav Werkzeuge connects the product capabilities with a service model focused on reliable European supply and technical guidance. Metav’s stock and quality procedures act as a practical “quality filter” for workshop buyers, reducing uncertainty about tool origin and batch consistency. As a companion to the tool itself, this service layer supports operational planning and ensures access to the required spare parts and consumables in continuing production runs.

FAQ

Which inserts are compatible with this cutter?
The cutter is compatible with RDMT 12T3 indexable inserts; selecting the appropriate insert grade will tailor the R242TM’s performance to the machining task.

What shank size is required for safe clamping?
A 32 mm holder or collet is recommended to achieve the rigidity intended for this tool and to maintain consistent run-out during operations.

How many cutting edges does the tool use and what is the benefit?
The tool employs three cutting edges, which provides a compromise between feed rate potential and chip load distribution, supporting steady removal rates with reduced vibration.

Is the cutter suitable for heavy-duty milling applications?
The robust shank and indexable design of the R242TM make it suitable for many production scenarios where insert-based machining is standard; insert selection and machine stability determine final capacity.

What fastening components are supplied with the tool?
The tool uses a locking screw (M3,5) and Torx screw (M3,5x8,5) secured with a T15 key to mount inserts securely and facilitate quick changes.
