Bohrstange SIL S25R — Boring bar for SIL for 16-22ER indexable inserts, left-hand

The Bohrstange SIL S25R is a left‑hand boring bar designed for turning operations that use 16 ER style indexable inserts; it is intended for workshop and industrial lathe applications where repeatable geometry and quick insert changes are required.

• Teknik Makina SIL S25R boring bar
• Compatible with 16 ER indexable inserts
• Shaft Ø 25 mm, overall length 200 mm
• Left-hand cutting direction, weight 0.765 kg

Improved machining stability for consistent surface quality

The combination of a 25 mm shaft diameter and a 200 mm overall length makes this boring bar well suited to tasks that demand reduced vibration and improved repeatability. A more rigid support reduces chatter and leads to a more consistent surface finish, while the measured mass contributes to damping during cut. These mechanical advantages translate into fewer rejects and more predictable cycle times, which supports higher throughput in component production.

Broad insert compatibility and efficient tool changes

Designed for use with 16 ER indexable inserts and compatible with the SIL series for 16–22ER sizes, the holder accommodates standard insert geometries and enables fast replacement without complex set‑ups. The cutting height 45 mm and nominal diameter 29 mm ensure correct rake and clearance when paired with matching inserts, helping to maintain cutting geometry and extend insert life. The specification is particularly useful when multiple insert grades are tested for feed and speed optimisation.

Practical workshop integration and reliable handling

With a compact mass of 0.765 kg, the tool balances manageability and stability for daily shop use; it is robust enough for continuous operation yet straightforward to handle during set‑up. The left‑hand cutting direction is clearly indicated for correct installation and safe operation. Supplied as an ISO‑designated SIL S25R component, the bar fits established clamping systems (ER16), allowing seamless replacement within existing tool stocks and minimising downtime for retrofits or upgrades.
