S20Q SVUBL boring bar (SVUB for VBMT indexable inserts) — Teknik Makina, left-hand cutting

The S20Q SVUBL boring bar is engineered for left-hand internal turning with VBMT 1103 indexable inserts, offering a rigid 20 mm shank and an 180 mm overall length for use in CNC turning and finishing tasks.

• Shaft Ø 20 mm for high rigidity
• Compatible with VBMT 1103 inserts
• Left-hand cutting direction
• Overall length 180 mm for extended reach

Stable internal turning through improved rigidity

The boring bar is designed to reduce vibration and improve process stability; a 20 mm shank diameter provides a stiff connection to the toolholder that lowers deflection during cut. With a 32 mm cutting height and a 25 mm external diameter, the bar offers a balanced geometry that helps maintain consistent cutting forces and surface finish. Where concentricity and repeatability matter, the assembly is engineered so that the insert seat and clamp interface ensure predictable positioning, which supports tight tolerances on internal bores.

Fast adaptation and predictable insert performance

Compatibility with VBMT 1103 indexable inserts enables quick tool changes and predictable wear behaviour. The SVUB clamping concept secures the insert with repeatable seating, so index changes are done efficiently and tool downtime is minimised. The left-hand orientation is already integrated into the bar geometry, avoiding adapter workarounds for reverse-direction operations. This combination allows process planners to standardise on an insert family while retaining flexibility for finishing or semi-finishing operations.

Practical integration into production workflows

An overall length of 180 mm gives the bar reach for internal features without excessive overhang, while the specified 93° cutting angle supports stable engagement in typical bore applications. The unit weight of 0.7 kg contributes to manageable handling at setup and reduces inertia during rapid toolpath changes. Documentation and ISO designation S20Q SVUBL support traceability and tool management in maintenance records, and the simple clamping designation "11" assists in selecting compatible holders and fixtures for quick assembly.

FAQ

Which inserts fit this boring bar?
The S20Q SVUBL boring bar is specified for VBMT 1103 indexable inserts and the SVUB clamping style, ensuring correct seating and repeatable index changes.

Is the cutting direction fixed or reversible?
This bar is supplied for left-hand cutting orientation; reversal requires a different bar geometry or holder designed for right-hand cutting.

What are the key dimensions for holder selection?
Relevant dimensions include a 20 mm shank diameter, 180 mm overall length and a 25 mm external diameter; these values guide holder clearance and support choices.

Can the bar be used for extended reach applications?
The 180 mm overall length provides moderate reach for internal turning; longer overhangs will increase deflection and should be evaluated against process tolerances.

What is the SKU for ordering and traceability?
Order or reference the tool using SKU K284TM, which identifies the Teknik Makina S20Q SVUBL boring bar.
