Boring Bar STFC for TCMT Indexable Inserts — left‑hand, internal‑coolant toolholder (Teknik Makina)

The Boring Bar STFC for TCMT Indexable Inserts is a left‑hand turning toolholder with internal coolant, designed for use with TCMT 1102 indexable inserts in external turning and facing operations.

• Internal coolant for effective chip evacuation
• Left‑hand cutting for reverse‑direction turning
• Compatible with TCMT 1102 indexable inserts
• 20 mm diameter, 180 mm overall length

Greater rigidity for consistent cycle times

The STFC geometry and a 90° cutting angle provide a solid support platform that reduces chatter and improves surface finish. With a compact 20 mm outer diameter and shaft 16 mm, the toolholder offers a balance between accessibility and stiffness, which translates into reduced scrap rates and more predictable machining times. The integrated internal coolant directs cutting fluid to the insert cutting edge, lowering temperatures during heavy cuts and thereby extending insert life. For production environments seeking reliable throughput, this combination supports efficiency gains without complex retrofit work.

Compatible inserts and simplified tooling logistics

Designed for TCMT 1102 indexable inserts, the toolholder accepts commonly stocked turning grades and geometries for quick changeovers. The STFC designation indicates an insert seat optimised for secure clamping and controlled chip flow; this means the same insert families can be used across different holders, simplifying inventory. The left‑hand cutting orientation is specified for operations where the lathe or the workpiece requires reverse‑direction turning — the design ensures the insert faces the correct cutting forces. Clear identification of insert type and seat geometry supports straightforward tool selection and reduces setup time.

Practical workshop advantages and maintenance ease

At an overall length 180 mm and weighing 0.289 kg, the toolholder is compact to handle yet robust enough for repeatable performance in batch and jobbing shops. The accessible design of the clamp and insert pocket enables fast insert indexation and inspection, reducing downtime for maintenance. Internal coolant reduces the need for external nozzles and helps maintain a clean workpiece and tool area, contributing to safer, more ergonomic working conditions. Supplied in a standard ISO seat (A12K STFCL), the component integrates into existing tool chains with minimal adaptation and supports predictable tool life planning.

FAQ

What inserts fit this boring bar?
The boring bar is designed for TCMT 1102 indexable inserts; the STFC seat secures the TCMT shape for standard clamping and chip control.

Is the tool suitable for left‑hand turning only?
Yes, the toolholder is configured for left‑hand cutting, intended for reverse‑direction turning operations where the insert orientation matches left‑hand cuts.

How does internal coolant benefit machining with this tool?
Internal coolant delivers fluid directly to the cutting edge, lowering temperatures, improving chip evacuation and extending insert life compared with external coolant alone.

Can the bar be used in confined spaces?
With a 20 mm diameter and 180 mm overall length, the holder is compact and suited to restricted access operations while maintaining sufficient rigidity.

What ISO designation does the holder use?
The holder carries the ISO designation A12K STFCL, which identifies the seat geometry and mounting style for compatibility with matching toolposts.
