Boring Bar S25R SDQCR by Teknik Makina – SDQC holder for DC-- 11T3 indexable inserts, 25 mm shank

A Boring Bar S25R SDQCR tailored for right-hand internal turning with SDQC clamping for DC-- 11T3 indexable inserts, optimised for workshop throughput and secure mounting

• 25 mm shank diameter for secure clamping
• Compatible with DC-- 11T3 indexable inserts
• 200 mm overall length for deep boring

Reduced vibration through a rigid shank and secure mounting

The S25R SDQCR designation identifies a holder with a 25 mm shank intended for stable toolpost mounting. A rigid shank reduces chatter and improves surface finish by keeping the cutting geometry constant under load. With a compact mass of 0.748 kg, the tool balances stiffness with manageable handling; the result is fewer interrupted passes and a more predictable process when machining internal bores. This technical stability supports consistent component quality and lowers scrap rates.

Faster indexable insert changes for less downtime

The SDQC clamping system is designed specifically for use with DC-- 11T3 indexable inserts, enabling quick and repeatable insert replacement. Compatible insert seating ensures secure fixation without prolonged adjustment, which shortens maintenance intervals and increases machine uptime. By choosing an indexable solution, workshops reduce per-part tooling costs and simplify logistics for consumables, turning changeover efficiency into a measurable productivity gain.

Geometry that promotes reliable cutting and tool life

A cutting angle of 107.5° and a cutting edge height of 40 mm contribute to a controlled cutting action and effective chip formation. These geometric characteristics help distribute cutting forces over the insert, reducing local overload and supporting longer insert life under comparable conditions. Clear chip flow and predictable contact angles lead to fewer surface defects and more consistent tolerance attainment on internal diameters.

Reach and access for demanding internal turning

With a 32 mm diameter and 200 mm overall length, the bar is suited to applications that require extended reach into workpieces while maintaining a secure connection to the toolholder. The dimensional combination allows for deeper internal operations without sacrificing the mechanical connection at the shank, which is essential for achieving concentricity and repeatable bore geometry in serial production or repair work.

Machine compatibility and orientation guidance

This tool is configured for right-hand cutting and requires a toolpost or turret that accepts a 25 mm shank. The standard ISO-style designation simplifies selection for integration into existing turning centres and CNC lathes. Prior to installation, verify that the machine set-up allows for the required clearance and that the insert seating aligns with the SDQC pocket to ensure full indexability and correct cutting geometry.

Handling advice and operational best practice

The bar's moderate weight and compact form make handling straightforward, but correct clamping is critical: ensure the shank is firmly seated and the clamping screws are torqued according to the insert and toolholder recommendations. Regular inspection of insert seating and clean contact faces will preserve repeatability and reduce the risk of premature wear. For application-specific guidance, consult the insert manufacturer's data and Metav Werkzeuge's technical advisors.
