A20Q SDQCL boring bar by Teknik Makina — left-hand, internal coolant, Ø25 mm head

the A20Q SDQCL boring bar is a left-hand toolholder designed for precision boring with DC-- 11T3 indexable inserts, offering integrated coolant supply for improved chip evacuation and stable cutting

• Left-hand cutting direction
• Internal coolant supply enabled
• Compatible with DC-- 11T3 inserts
• Ø25 mm head, 20 mm shank

Stable support for accurate internal boring

The toolholder delivers a rigid platform that reduces vibration during internal machining, translating into consistent diameters and surface quality. Its compatibility with indexable inserts such as DC-- 11T3 makes insert changes quick and repeatable, reducing downtime. The A20Q SDQCL designation denotes the ISO-style mounting and geometry, ensuring predictable clamping and reproducible cutting positions across multiple set-ups.

Controlled cooling and chip management for longer tool life

An integrated internal coolant channel directs lubricant to the cutting edge, improving cooling and aiding chip control in confined bores. This targeted supply helps to dissipate heat, reducing insert wear and the risk of edge build-up. The tool’s cutting angle 107.5° supports favourable chip flow for many typical operations, enabling more consistent cycle times and fewer unscheduled tool changes.

Compact geometry for predictable set-up and balance

With a Ø25 mm head and 20 mm shank, and an overall length of 180 mm, the boring bar offers a compact footprint that simplifies tool projection planning and balance on the turret. A cutting height of 32 mm ensures correct insert placement and stable cutting engagement, while a modest weight of 0.425 kg aids rapid machine acceleration without sacrificing rigidity. These dimensions make the bar straightforward to integrate into existing toolholding systems.

Practical fitment and workshop advantages

Designed for indexable insert applications, the bar fits insert type DC-- 11T3 and pairs with clamp-holder designation 11 for secure mounting. The left-hand orientation suits applications where reverse-direction boring is required or where turret layout dictates. For workshops seeking a reliable, coolant-fed solution that streamlines insert changes and maintains repeatable bore quality, this cutter offers a focused, production-friendly option
