Boring Bar S20R MWLNR – Indexable insert tool holder, 20 mm shank (Teknik Makina)

The Boring Bar S20R MWLNR is a right-hand tool holder engineered for turning operations with MWLN-style indexable inserts, designed to provide stable cutting and accurate bore finishing in workshop and production environments

• S20R MWLNR designation for secure fit
• Fits WN-- 0604 indexable inserts
• 20 mm shank diameter for stable clamping
• 200 mm overall length for deep bore access

Consistent rigidity for predictable machining results

The S20R MWLNR designation signals a tool engineered for precision and repeatable performance. With a 20 mm shank, the tool offers increased stability at the toolpost, which reduces vibration and supports a consistent surface finish and longer insert life. In practical terms, greater rigidity means fewer rework cycles and steadier cycle times on serial turning tasks; this is an efficiency gain that pays off across production runs. The lightweight mass of 0.502 kg also aids handling during set-up without compromising clamp stability.

Economical tooling through standardised insert compatibility

Using indexable inserts with a standard geometry keeps tooling costs under control. The bar is compatible with WN-- 0604 inserts in an MWLN pocket, allowing quick insert changes and easy stocking of replacement items. For teams unfamiliar with indexable tooling: inserts are replaceable cutting tips that eliminate the need to regrind the whole tool, so downtime is reduced and tool inventory becomes modular. This approach supports predictable operating costs and faster turnaround in maintenance cycles.

Designed for access and controlled cutting action

A 200 mm overall length and a nominal 25 mm diameter profile enable access to deeper bores while maintaining control over chip flow. The tool presents a 95° cutting angle and is set up for right-hand cutting, which suits most conventional lathe feed directions. The specified cutting height 50 mm helps ensure the insert sits correctly in the toolholder geometry, supporting consistent engagement with the workpiece and reliable material removal rates. These dimensions help machinists plan fixture clearances and optimise approach angles for best surface integrity.

Smooth integration into workshop tooling systems

The bar is supplied to the S20R MWLNR ISO designation, which simplifies matching to existing toolholders and holders compliant with the same standard. Assembly and changeover routines become straightforward when components follow common formats, supporting faster set-ups and higher machine availability. As a Teknik Makina product, the component benefits from a clear production specification and is distributed via Metav Werkzeuge, whose European stock and logistics act as a quality filter for reliable supply chains and reduced lead times.
