Boring Bar S25S — 25 mm shank, 250 mm overall length | Teknik Makina

The boring bar S25S is a precision tool holder for SCMT 1204 indexable inserts, engineered for internal turning tasks in workshop and production environments

*25 mm shank diameter for stable clamping
*Compatible with SCMT 1204 indexable inserts
*Overall length 250 mm for extended reach

Precision and stability for repeatable internal turning

The design of this tool is focused on rigidity and repeatable results. A 25 mm shank combined with the S25S designation provides a compact yet stiff connection to the machine spindle or tool post, reducing vibration and improving surface finish in bore machining. A 19.5 mm clamping head width helps maintain secure seating of the insert holder, which translates into consistent tool life and fewer reworks. These attributes support higher feed rates and steadier cutting conditions, improving throughput without sacrificing accuracy.

Simple insert fitting and secure fastening for quick changeovers

Fitted for SCMT 1204 indexable inserts, the holder allows fast replacement of cutting edges without complex setup. The insert is retained with an M5x12 Torx screw tightened using a Torx T20 key, ensuring repeatable clamp force and minimal runout after each index. Indexable inserts offer an economical approach to tool management: when an edge dulls, a quick index or replacement restores cutting geometry without regrinding, lowering per-part tooling costs and simplifying workshop logistics.

Extended reach and directed cutting for practical workshop use

An overall length of 250 mm provides the reach required for medium-depth bores while keeping the overhang manageable to limit deflection. The tool is configured for right-hand cutting with a modest 3° cutting angle and a 30 mm cutting height, balancing chip formation and stability. At approximately 0.72 kg, the assembly is light enough for straightforward handling yet heavy enough to dampen minor vibrations. Its compact geometry and measured mass make it suitable for conventional and CNC lathes where controlled bore quality and repeatable setups are priorities.

FAQ

Is the holder suitable for SCMT 1204 inserts?
Yes. The boring bar S25S is specifically designed to accept SCMT 1204 indexable inserts and their standard clamping geometry.

What cutting direction does the tool support?
The tool is configured for right-hand cutting, making it suitable for standard clockwise spindle rotation in turning operations.

Which fastening components are required for the insert?
The insert is secured with an M5x12 Torx screw requiring a Torx T20 key for tightening and repeatable clamping.

How deep can I machine with this tool?
With an overall length of 250 mm, the holder provides extended reach for medium-depth bores while maintaining acceptable rigidity for accurate results.

Is this tool suitable for CNC and manual lathes?
Yes. The combination of a 25 mm shank and compact head geometry suits both CNC and conventional lathes where a stable, repeatable insert clamping system is required.
