A16Q SDQCL Boring Bar (KA276TM) — Left‑hand, internal coolant by Teknik Makina

A16Q SDQCL is a robust boring bar designed for left‑hand turning operations with SDQC geometry for DC-- indexable inserts

• Left‑hand cutting direction for specific orientations
• Internal coolant for improved chip evacuation
• Compatible with DC-- 11T3 indexable inserts
• 16 mm shank with 180 mm overall length

Precision and consistent surface quality for production turning

The A16Q SDQCL boring bar is engineered to deliver stable cutting performance in left‑hand operations. The 107.5° cutting angle provides a controlled engagement of the insert, which helps to reduce chatter and to maintain consistent surface finish during finishing passes. For manufacturers aiming to tighten tolerances and lower rework rates, this toolholder offers a reliable platform for repeatable results, combining geometric stability with straightforward insert seating.

Compact design that maximises rigidity at the tool post

With a 16 mm shank diameter, an effective 20 mm diameter body and an overall length of 180 mm, this toolholder balances reach and stiffness. The 30 mm cutting height and low mass (approx. 0.275 kg) minimise overhang‑related deflection, making the assembly less prone to vibration. These dimensional characteristics enhance cutting stability on small‑ to mid‑sized lathes and reduce the need for excessive reductions in feed or depth of cut to preserve part accuracy.

Insert compatibility and coolant management for longer tool life

Designed specifically for DC-- 11T3 indexable inserts, the SDQC pocket geometry ensures precise seating and repeatable clamping forces. The integrated internal coolant channel directs fluid to the cutting edge, improving chip evacuation, cooling the insert edge and helping to sustain cutting performance. For operations where chip control and thermal stability directly affect cycle time and insert life, this configuration supports longer, more predictable tool life and cleaner machining processes.

Practical advantages for workshop integration

The left‑hand orientation and compact form factor make this toolholder suitable for specialised turning set‑ups and for machines where tool approach or part orientation requires reverse cutting direction. The toolholder’s straightforward ISO designation and standard insert compatibility simplify inventory and changeover. If unsure whether this tool fits a specific machine or process, our technical team can advise on mounting and insert selection to avoid unnecessary downtime while ensuring optimal cutting conditions.

FAQ

What inserts fit the A16Q SDQCL boring bar?
The A16Q SDQCL is designed for DC-- 11T3 indexable inserts with SDQC pocket geometry, ensuring accurate seating and secure clamping.

Is the coolant internal or external on this toolholder?
This toolholder features internal coolant, which directs fluid to the cutting edge for improved chip evacuation and insert temperature control.

Which machines are best suited to use this boring bar?
The toolholder is suitable for lathes that accept a 16 mm shank and benefit from a compact tool overhang; its left‑hand orientation is ideal where reverse cutting direction is required.

How does the 107.5° cutting angle affect machining?
A 107.5° cutting angle moderates insert engagement, helping to reduce vibration and deliver a more consistent surface finish during finishing passes.

Will the A16Q SDQCL work for heavy roughing?
This configuration is optimised for precision turning and finishing; for heavy roughing, a larger, stiffer toolholder and insert grade selected for high material removal should be considered.
