Precise geometry for consistent internal turning results

The cylindrical design and dimensional control of this boring bar offer a balance between rigidity and accessibility that matters in production environments. With a 25 mm diameter body and 20 mm shank, the tool reduces deflection when mounted in standard toolholders, which improves dimensional consistency and surface finish. The measured mass and geometry contribute to predictable dynamic behaviour during internal turning cycles, supporting higher first-pass yield and reduced rework.

Compatibility and cutting geometry explained

Engineered for SDUC-style inserts, the tool accepts DC-- 11T3 indexable plates, a common format for internal facing and finishing operations. The 93° cutting angle provides an effective approach for bore edges and shoulder machining, while the left-hand cutting orientation suits operations where entry from the right-hand side improves access or chip evacuation. Specifying the correct insert grade and chipbreaker will align cutting performance with material and feed-rate requirements.

Built for efficient workshop integration

A 32 mm cutting height and 180 mm overall length give this toolholder a practical reach while keeping the centre of gravity close to the clamping face, simplifying set-up and balancing. The S20Q SDUCL format follows ISO-style designation for straightforward tool management and inventory control. The modest weight supports safer handling during changeovers and contributes to quicker machine set-up, reducing downtime between batches.

Reliability in repeat production and maintenance

Designed as a holder for indexable inserts, the assembly minimises maintenance effort: insert replacement is fast and repeatable, lowering toolhandling time in the cell. The combination of standardised insert compatibility and familiar mounting dimensions streamlines tool procurement and reduces the need for special adapters. For procurement and workshop planning, the well-documented ISO designation aids tool lists and fixture checks.

FAQ

What insert type fits this boring bar?
The boring bar accepts DC-- 11T3 indexable inserts in an SDUC pocket; selecting the correct grade and chipbreaker is advised for the workpiece material.

Is this tool suitable for finishing internal bores?
Yes, the geometry and 93° cutting angle make the tool appropriate for finishing operations when paired with a matching finishing insert.

What are the key dimensions for clamping and set-up?
Key dimensions: 25 mm body diameter, 20 mm shank diameter and 180 mm overall length (SKU K260TM) for correct toolholder selection.

Can the left-hand cutting orientation be used for conventional set-ups?
Left-hand cutting is intended for operations where the tool engages material in that direction; the orientation suits specific lathe set-ups and access conditions.

How does the tool support quick insert changes?
The SDUC-style holder uses standard clamping practices for indexable inserts, allowing fast replacement and repeatable seating without extensive re-adjustment.
