S12K SDQCL boring bar — 12 mm shank, for DC-- 0702 inserts (Teknik Makina)

The S12K SDQCL is a left‑hand boring bar designed for internal turning with DC-- 0702 indexable inserts, suitable for workshops and production lines requiring compact, repeatable toolholders

• Left-hand cutting direction SDQCL design
• Suited for DC-- 0702 indexable inserts
• 12 mm shank diameter, 125 mm overall length
• 25 mm cutting height, 107.5° cutting angle

Stable left‑hand turning for precision internal machining

The construction focuses on delivering stable, repeatable cuts in confined bores and internal profiles. With a 12 mm shank and a compact 125 mm overall length, the toolholder reduces overhang and vibration, which supports tighter tolerances and longer insert life. The left‑hand geometry (SDQCL) is optimised for applications where reverse cutting direction is required, and the 107.5° cutting angle helps control chip flow and cutting forces. This combination enhances process reliability and reduces scrap rates in serial production.

Fast changeover and compatible indexable inserts

Tool management is simplified by the holder’s compatibility with DC-- 0702 indexable inserts, enabling quick insert changes and consistent seating for repeatable results. The bore‑side design accepts the standard insert seating for this size, and the reference clamp code 07 specifies the compatible clamping interface for secure fixation. Reduced setup time and standardised consumables translate into measurable productivity gains across batch sizes, making this an efficient choice for workshops and CNC turning centres aiming to increase uptime.

Compact design that improves machining stability

A short effective length and low mass (0.12 kg) contribute to improved dynamic behaviour during cutting, especially in internal turning operations where rigidity is critical. The 25 mm cutting height provides adequate engagement for medium‑depth passes while maintaining balance between material removal and tool life. The toolholder’s compact profile is particularly useful for tight fixtures and multi‑axis set‑ups, where minimised interference and predictable tool runout are decisive for achieving consistent surface quality.

FAQ

What applications is this toolholder best suited for? The S12K SDQCL boring bar from Teknik Makina is intended for internal turning and threading set‑ups where a left‑hand cutting direction and compatibility with DC-- 0702 indexable inserts are required.

Which inserts are compatible with this tool? Compatibility is specified for DC-- 0702 indexable inserts; the holder accepts the standard seating for this insert type and uses clamp code 07 for secure fixation.

How does the shank size affect machining performance? A 12 mm shank reduces overhang and increases rigidity compared with larger, longer toolholders, improving vibration damping and repeatability during internal turning operations.

Can this toolholder be used in multi‑axis turning centres? Yes, the compact 125 mm overall length and low weight make the toolholder suitable for multi‑axis set‑ups where space is limited and stable tool behaviour is essential.
