Boring bar KA263TM (A32T SDUCL) — left-hand, internal coolant

the Boring bar KA263TM is a left-hand cutting tool designed for SDUC indexable inserts and engineered for secure clamping in precision boring operations

• Left-hand cutting for reverse-direction operations
• Internal coolant for reliable chip evacuation
• Shank Ø32 mm for secure clamping
• Compatible with DC-- 11T3 indexable inserts

Greater rigidity and predictable machining stability

The combination of a 32 mm shank and a body diameter of Ø40 mm provides measurable stiffness that reduces vibration during interrupted cuts. Built to the A32T SDUCL ISO designation, this boring bar is balanced for rotational stability; the mass of approximately 1.924 kg contributes to consistent tool behaviour under load. These characteristics translate directly into improved surface finish and tighter bore tolerances, as the toolholder geometry controls chatter and runout without complex setup changes.

Coolant-through design for improved tool life and chip control

An internal coolant channel supplies cutting fluid directly to the cutting edge, promoting better lubrication and heat dissipation at the insert radius. For indexable insert systems such as DC-- 11T3, targeted coolant reduces built-up edge and extends insert life, while aiding chip evacuation in deep bores. Explaining briefly: indexable inserts are replaceable cutting tips that allow fast tool renewal; pairing them with coolant-through boring bars helps maintain cutting performance and reduces the frequency of tool changes.

Optimised geometry for efficient material removal

A nominal 93° cutting angle and a 45 mm cutting height deliver effective chip formation and clearance in common boring tasks. With an overall length of 300 mm, the tool is suited to medium-depth bores where reach and stiffness must be balanced. These dimensions result in efficient metal removal rates while maintaining control over cutting forces; fewer passes are often required to achieve the final bore diameter, improving throughput without compromising accuracy.

Practical compatibility and workshop integration

Designed for machining centres and lathes configured for left-hand operations, the bar accepts DC-- 11T3 inserts and requires standard clamping for a 32 mm shank. Supplied by Teknik Makina and distributed through Metav Werkzeuge, the component integrates into existing indexable-insert tooling systems with minimal adaptation. For production environments seeking reproducibility, the use of standard insert grades and coolant-through capability supports consistent cycle times and simplifies spare-part logistics
