A25R SDQCL Boring bar — left-hand, internal coolant — Teknik Makina

The A25R SDQCL is a left-hand boring bar designed for the use with DC-- indexable inserts in turning and internal machining operations, delivering stability and reliable chip evacuation for industrial metalworking.

• Left-hand cutting direction for asymmetric parts
• Shank Ø 25 mm for stable clamping
• Internal coolant for improved chip removal
• Compatible with DC-- 11T3 indexable inserts

Enhanced stability for precision internal turning

The boring bar is built around a shank Ø 25 mm, giving a robust clamping interface that reduces vibration and runout during heavy cuts. With an overall length of 200 mm and a tool diameter of 32 mm, the design balances reach and rigidity, helping to preserve dimensional accuracy when machining bores or internal profiles. The measured mass of 0.738 kg contributes to predictable dynamic behaviour on the turret, which in turn supports repeatable bore tolerances and a reliable surface finish.

Reliable chip control that protects tool life

Equipped with internal coolant, the tool routes cutting fluid directly to the cutting edge to improve chip evacuation and reduce thermal load on the cutting zone. This targeted cooling lowers the risk of built-up edge and tool wear, so insert life is extended and cycle times remain consistent. In practice, improved coolant delivery supports cleaner chips, fewer interruptions for chip clearing and a more consistent process capability in longer production runs.

Fast insert changes and defined cutting geometry

Designed for DC-- 11T3 indexable inserts and a clamping holder designation of 11, the tool allows quick insert replacement without regrinding, reducing downtime. The cutting height of 40 mm and a cutting angle of 107.5° provide a defined engagement geometry that eases process setup and supports predictable cutting forces. Using standardised insert types simplifies stocking and ensures that the cutting edge can be restored in minutes, maintaining throughput in job-shop or production environments.

Practical integration into CNC turning cells

With the ISO designation A25R SDQCL, the component is straightforward to specify and install in existing tool assemblies. The left-hand cutting orientation suits applications requiring opposite-direction cutting or when machining features from a particular approach angle. Compatibility with a common insert seat and the combination of shank Ø 25 mm, 200 mm overall length and internal coolant make this a pragmatic choice for workshops seeking a balance between accessibility, rigidity and effective coolant management.
