S12K STFCL boring bar – STFC for TCMT indexable inserts, left-hand

The S12K STFCL boring bar is a left-hand internal turning holder designed for use with TCMT 1102 indexable inserts, offering a compact shank and a 90° cutting configuration for reliable lathe operations.

• ISO designation S12K STFCL compatible
• For TCMT 1102 indexable inserts
• Left-hand cutting direction, 90° angle
• Shank Ø12 mm and 125 mm overall length

Stable mounting and precise insert compatibility for repeatable results

The S12K STFCL designation denotes a standardised shank and clamping geometry that simplifies tool selection and machine setup. With compatibility for TCMT 1102 indexable inserts, the holder ensures repeatable insert seating and consistent cutting edge position, which reduces the need for frequent readjustment. This results in a predictable machining process and supports shorter machine downtime when replacing inserts.

Rigid design that reduces vibration and improves surface finish

A shank Ø12 mm combined with a 16 mm diameter cutting section and a compact 125 mm length provides a stiff tool assembly that helps suppress chatter in typical internal turning applications. The reduced deflection improves surface quality and dimensional stability, especially in finishing passes where a 90° cutting angle and left-hand cutting orientation are required. The tool's modest weight (0.118 kg) contributes to easier handling without compromising rigidity.

Efficient insert handling and lower operating cost

Designed for indexable inserts, the holder allows fast replacement of worn cutting edges without full tool withdrawal from the machine. This modular approach supports efficient production workflows: inserts can be rotated or exchanged quickly, lowering tooling consumption and contributing to a leaner process. The left-hand configuration suits turning operations where the workpiece feed and lathe set-up demand a reversed cutting direction.

Practical setup and shop-floor advantages

The compact holder size and standard ISO labelling facilitate rapid identification and integration into existing toolbanks and spindle arrangements. Clear designation and standardised clamping reduce set-up errors and accelerate changeover times at the machine. The straightforward geometry also aids in programming and fixture planning, making the holder suitable for workshops seeking dependable, easy-to-standardise tooling components.
