SIR S25R boring bar – holder for IR16 indexable inserts, 25 mm shank

SIR S25R is a compact boring bar designed for indexable IR inserts, optimised for stable, right‑hand cutting in workshop and CNC environments

• SIR S25R holder for 16 IR inserts
• 25 mm shank for secure clamping
• 45 mm cutting height for deep cuts
• Right‑hand cutting direction

Stable clamping for consistent tool life

The holder’s 25 mm shank and solid construction reduce vibration and deflection during cutting, which preserves insert geometry and extends tool life. In practice, a rigid shank diameter means repeatable bore accuracy and fewer scrap parts; the specified 45 mm cutting height supports deeper engagement without compromising stability. For production tasks that demand repeatability, this combination improves first‑pass yield and reduces downtime typically caused by rework.

Fast insert changes and clear replacement parts

Indexable inserts minimise maintenance time because worn edges are replaced instead of the whole tool; the bar is configured for 16 IR inserts and secured with a Torx T15 drive and M3.5x11 screw for reliable clamping. The straightforward fastener arrangement and the use of standard components such as the U plate TA060 make replacement and setup quicker for operators and maintenance staff. This reduces machine idle time and allows predictable scheduling of tool changes.

Compact dimensions for flexible workshop integration

With a 29 mm diameter, 200 mm total length and a weight of 0.76 kg, the tool offers a balance between stiffness and manoeuvrability for a wide range of setups. The right‑hand cutting orientation is suited to conventional turning and boring cycles on most lathes and CNC machines. Compatibility notes such as the included shim BSP010 and the matching clamping head IR16 assist planners in ensuring proper fitment and avoiding unnecessary adaptations.

FAQ

What insert type fits this boring bar?
The bar is configured for 16 IR indexable inserts; use compatible IR16 inserts for correct seating and performance.

Which clamping hardware is required for insert replacement?
Insert clamping uses a Torx T15 key and M3.5x11 screw; spare fasteners of the same specification are recommended.

Is the bar suitable for deep boring operations?
The 45 mm cutting height supports deeper cuts while the 25 mm shank helps maintain rigidity for consistent results.

Can this tool be mounted in standard holders?
The bar’s dimensions (25 mm shank, 29 mm diameter, 200 mm length) allow integration in many common tool setups; check compatibility with the clamping head IR16 and the shim BSP010.

What cutting direction does the tool support?
The product is designed for right‑hand cutting, matching conventional right‑hand machining cycles.
