A25R SDUCR Boring Bar – SDUC for DC-- indexable inserts, right-hand, internal coolant (Teknik Cutting Tools)

The A25R SDUCR is a right-hand boring bar for internal machining, designed to accept DC-- 11T3 indexable inserts and to run with through-tool coolant for improved chip evacuation

• Compatible with DC-- 11T3 indexable inserts
• Internal coolant for reliable chip evacuation
• Ø40 mm body, 300 mm overall length
• Right-hand cutting, robust 32 mm shank

Stable internal machining with precision geometry

The A25R SDUCR holder combines a firm Ø40 mm body with a 32 mm shank to deliver improved rigidity during deep internal operations. The modest overhang and balanced mass reduce chatter and deflection, which translates into consistent bore quality and longer insert life. For workshop managers and production engineers, this means fewer rework cycles and a steadier process window when introducing new workpieces or materials.

Reliable chip control through internal coolant

Equipped with internal coolant, the holder channels cutting fluid directly to the cutting edge for effective cooling and chip evacuation. This targeted delivery reduces heat at the cutting zone and helps prevent built-up edge on the insert, supporting longer tool life and more predictable surface finishes. In practice, this results in fewer interruptions for manual chip clearing and a smoother machining rhythm on repeat runs.

Quick compatibility for standard insert systems

Designed specifically for DC-- 11T3 indexable inserts, the SDUC configuration simplifies tool setup and replacement. The insert interface enables straightforward clamping and repeatable positioning, reducing downtime during tool changes. For workshops standardising tooling, the proven insert family provides a cost-effective way to maintain cutting-edge performance across multiple operations.

Practical dimensions for production environments

With a total length of 300 mm and a cutting height of 45 mm, the holder suits many internal turning and boring situations where reach and stability must be balanced. The geometry supports right-hand cutting at a 93° cutting angle, offering a stable approach for cylindrical features and smaller internal diameters. The substantial mass (approx. 1.924 kg) further contributes to vibration damping in medium-duty to heavy finishing passes.

FAQ

Which insert type is required for this holder?
The holder accepts DC-- 11T3 indexable inserts; the SDUC seat is designed for secure, repeatable clamping of that insert family.

Does the bar allow through-tool coolant?
Yes, the toolholder features internal coolant to deliver cutting fluid directly to the cutting edge and support chip evacuation.

What are the key dimensions to consider for fixture setup?
Important dimensions are Ø40 mm body diameter, 300 mm overall length and a 32 mm shank diameter—these determine clearance and clamping requirements.

Is the cutting direction fixed?
The holder is configured for right-hand cutting, suited to standard internal turning and boring directions.

What is the ISO designation of the toolholder?
The ISO designation is A25R SDUCR, indicating the holder geometry and orientation for SDUC-style inserts.
