Boring Bar A25R STFCR — STFC Holder for TCMT Indexable Inserts (Teknik Makina)

The Boring Bar A25R STFCR is a right-hand STFC toolholder designed for precision internal boring and finishing using TCMT 1102 indexable inserts in workshop and light industrial turning applications

• Right-hand cutting direction
• Internal coolant feed enabled
• Compatible with TCMT 1102 inserts
• Ø 16 mm outer diameter, 125 mm overall length

Stability and repeatable precision in internal boring

The holder delivers consistent concentricity thanks to its compact geometry and defined shank dimensions. With a 12 mm shank diameter and an effective outer diameter of 16 mm, the tool provides a stable connection to the toolpost, reducing vibration during finishing passes. This stability improves surface finish and lowers the risk of premature insert wear, which in turn supports predictable cycle times and fewer rework operations. The ISO designation A25R STFCR indicates a standardised interface for clamping and repeatable mounting in standard toolholders.

Controlled coolant and chip evacuation for improved tool life

Integrated internal coolant is routed directly to the cutting zone to aid heat dissipation and chip formation. When used with TCMT 1102 indexable inserts, the coolant reduces thermal loading on the insert corner and promotes controlled chip breaking, particularly on harder or abrasive materials. The 90° cutting angle combined with right-hand cutting direction gives an efficient cutting geometry for internal boring and light grooving, helping to maintain tool life and machining stability over longer production runs.

Compatibility, workshop efficiency and straightforward handling

Designed for straightforward integration into existing setups, the STFC-style holder accepts widely used triangular TCMT inserts and fits standard clamping systems. The compact 125 mm overall length and low mass (approx. 0.053 kg) make it suitable for tight bores and confined tool posts where balance and minimal overhang are important. Using standard indexable inserts simplifies inventory and reduces downtime: worn cutting edges are replaced quickly without regrinding, supporting more efficient shift patterns and predictable throughput.

FAQ

What insert type fits this holder?
The holder accepts TCMT 1102 indexable inserts; the STFC clamping ensures secure seating and repeatable positioning for each indexed corner.

Is internal coolant available on the tool?
Yes — the A25R STFCR boring bar is supplied with internal coolant capability to deliver fluid directly to the cutting edge and improve heat control.

What are the key dimensions to check for machine compatibility?
Check the 16 mm outer diameter, 12 mm shank diameter and 125 mm overall length to ensure the tool fits the toolpost and the bore depth available.

Which cutting direction is specified for this tool?
The tool is configured for right-hand cutting, suitable for standard internal turning operations where right-hand feed is required.

Can the tool be used for finishing passes in tight bores?
Yes — the compact design and 90° cutting geometry make the tool suitable for controlled finishing passes in restricted internal spaces.
