S50U MWLNR Boring bar — 50 mm shank, 350 mm overall length (Teknik Makina)

A S50U MWLNR boring bar engineered for heavy-duty internal turning, optimised for MWLN-style indexable inserts and right-hand cutting applications.

• S50U MWLNR ISO shank, robust 50 mm
• Suitable for WN-- 0804 indexable inserts
• Right-hand cutting with 350 mm overall length

Consistent clamping and concentricity for repeatable bore quality

The bar is built around a 50 mm shank designed to provide stable clamping in standard holders, which reduces runout and improves surface finish during internal machining. With a 63 mm body diameter and a measured mass of 5.11 kg, the component delivers inertia that dampens vibration, so single-pass operations are more consistent. The ISO designation S50U MWLNR corresponds to established tooling standards, which simplifies integration into existing toolholders and reduces setup time.

Geometry tuned for controlled chip flow and reliable cutting

A defined 95° cutting angle and a cutting height of 65 mm ensure that the insert seat and rake geometry promote predictable chip formation when using WN-- 0804 inserts. The right-hand cutting configuration is matched to standard lathe feed directions and is recommended where radial stock removal is required. Key geometric choices are aimed at efficient material evacuation, which in turn extends insert life and lowers the frequency of tool changes.

Workshop-ready length and handling for deep bores

The 350 mm overall length provides extended reach for deeper internal turning tasks while preserving stiffness through its 50 mm shank. Machining longer bores is supported by the bar’s balanced dimensions, allowing for safer, more controlled passes without excessive deflection. The combination of reach and rigidity makes it suitable for medium-to-heavy duty internal operations in both single-part and small-batch production environments.

Compatibility and straightforward tooling choices

Designed for MWLN-style indexable inserts, the bar accepts WN-- 0804 inserts and pairs with common clamping systems (designation 08) for rapid insert changes and secure seating. The standardised interface reduces the need for bespoke tooling and enables straightforward replacement with widely available inserts. Where workshop logistics favour inventory reduction, the bar’s compatibility with established insert families simplifies procurement and stocking.

FAQ

What insert type fits this boring bar? The boring bar is designed for WN-- 0804 indexable inserts and conforms to the MWLN insert family guidance for reliable seating and chip control.

Is the bar suitable for deep internal turning operations? Yes; the 350 mm overall length and 50 mm shank provide reach and stiffness suited to deeper internal turning while maintaining acceptable rigidity.

What is the recommended cutting direction? The tool is configured for right-hand cutting, matching standard lathe feed directions and conventional internal turning setups.

Which ISO designation should be referenced for holder selection? Refer to S50U MWLNR as the ISO designation when selecting compatible toolholders or confirming holder compatibility.

How does the bar affect vibration and surface finish? The larger 50 mm shank and 63 mm body diameter increase mass and damping, reducing vibration and improving finish compared with smaller-diameter alternatives.
