KA310TM Boring Bar — 20 mm, internal coolant, for VBMT 1103 (Teknik Makina)

The KA310TM is a purpose-built boring bar for left-hand turning operations, optimised to accept VBMT 1103 indexable inserts and to supply coolant directly to the cutting edge for improved process stability.

• 20 mm diameter for stable cutting
• Integrated internal coolant delivery
• Compatible with VBMT 1103 inserts

Improved process stability and repeatable results

The rigid 20 mm body paired with a 16 mm shank and the ISO designation A16Q ensures a balanced combination of stiffness and accessibility in confined setups. This geometry reduces deflection during radial cuts, which translates into consistent bore diameters and repeatable surface quality across batches. The specified cutting angle of 107.5° helps to distribute cutting forces and to prolong insert life, making the toolholder a pragmatic choice where dimensional accuracy and uptime are priorities.

Controlled cooling and efficient chip management

Built with internal coolant routing, the tool delivers coolant directly to the cutting zone to aid heat dissipation and to flush chips away from the insert pocket. This targeted cooling reduces thermal distortion and supports steadier cutting conditions, particularly beneficial when working at higher spindle speeds or with interruption-prone bores. The clamping head width of 11 mm and a cutting height of 30 mm are tailored to secure VBMT 1103 inserts reliably, improving chip flow and lowering the risk of built-up edge.

Fast insert changes and low-maintenance operation

Designed for pragmatic workshop routines, the bar uses a Torx T8 key and an M2.5x6.5 Torx screw for insert fixation, enabling quick, tool-assisted indexable insert replacement with minimal downtime. The straightforward fastening concept reduces maintenance complexity and keeps changeover times predictable—an efficiency gain for production cells and repair shops alike. The reduced service time supports higher machine availability and a better cost-per-part ratio over repeated operations.

Suitable for precision shops and production environments

Lightweight at approximately 0.276 kg and with an overall length of 180 mm, the bar is compact enough for close-quarters setups yet long enough to reach recessed bores in many lathe configurations. Its left-hand cutting orientation aligns it to specific turning strategies and tooling layouts, offering a specialised option where reversal of cutting direction is required. The combination of compact dimensions and robust features makes this tool appropriate for small-batch precision work as well as integration into larger CNC turning cells.
