Precision boring bars with internal coolant for deep hole accuracy
Boring bars with internal coolant are precision tools designed to enlarge and finish existing holes, delivering tight dimensional and form tolerances while preventing tool breakage and surface damage; they are essential for deep bores and blind holes where external cooling cannot reach the cutting edge. These systems force high-pressure coolant through axial channels directly to the cutter, which reduces thermal stress and efficiently evacuates chips, making them ideal for machining difficult-to-cut or long-chipping materials. As a compact tool solution they combine rigidity, chip control and cooling to improve cycle times and extend tool life, with the main advantages being enhanced hole quality, repeatability and reduced rework for production and maintenance machining operations.

This geometry, specified by the ISO designation S20Q SD-CR, supports consistent bore profiles and surface finish. The indexable insert system with DC-- 11T3 inserts permits rapid insert replacement; this reduces downtime compared with brazed or solid tooling and keeps production run-times predictable. The stated 62.5° cutting angle contributes to controlled chip flow and predictable cutting forces. Improved process reliability and reach for internal turning With an overall length of 180 mm and a designed cutting height of 35 mm, the bar provides sufficient reach for moderate-depth internal operations while maintaining clamping stability via its 20 mm shank. Right-hand cutting orientation offers standard compatibility with common lathe setups and CNC boring heads. The modest mass (approx. 0.443 kg) keeps inertial forces low, aiding rapid acceleration and deceleration in automated cycles; this supports higher throughput without sacrificing positional control. The ISO-style shank ensures straightforward integration into existing toolholders. Easy integration into indexable-insert workflows Designed specifically for indexable inserts, the bar accepts the DC-- 11T3 family, simplifying stock management and spare-part logistics. The SD-CR geometry focuses on reproducible clamping and repeatable cutting-edge position, which is beneficial when switching between batches or when quick reconditioning is required. For procurement and maintenance planning, the compact design reduces storage footprint and the insert-based concept lowers per-cutting-edge replacement cost compared with solid tools, while preserving the quality demanded in precision internal machining.

Achieve exact bores with a boring bar with internal coolant
A boring bar with internal coolant is a specialised tool for internal machining on lathes and machining centres, designed to enlarge and finish existing holes to precise dimensional and form tolerances. Also referred to as an internal coolant boring bar or coolant‑fed boring bar, this tool class routes coolant through the tool body so that cutting edges are supplied directly with fluid under pressure.
How internal coolant keeps deep and blind bores reliable
When machining with external coolant only, the fluid is delivered from outside via machine nozzles and often fails to reach the cutting zone in longer bores, leaving chips trapped and increasing thermal load. A boring bar with internal coolant contains axial coolant channels that run through the tool shank to the cutting edge, delivering high‑pressure coolant where it is needed. This arrangement is essential for machining deep bores, blind holes and for materials that produce long, continuous chips; it lowers local temperatures, flushes chips out of the bore and reduces the risk of tool breakage and surface damage.
Key advantages that improve productivity
- Faster cycle reliability: internal coolant reduces thermal distortion and helps maintain tight tolerances over longer runs.
- Improved chip evacuation: pressurised coolant clears chips from the cutting zone, preventing chip clogging and re-cutting.
- Extended tool life: cooler cutting edges and effective flushing reduce wear and the likelihood of catastrophic tool failure.
- Process versatility: suitable for deep bores and blind holes, especially in difficult‑to‑machine or long‑chipping materials.

FAQ
When should a boring bar with internal coolant be chosen over external coolant?
Select a boring bar with internal coolant whenever bores are deep or blind, or when machining hard‑to‑cut or long‑chipping materials; the internal coolant ensures reliable chip evacuation and temperature control where external coolant cannot reach.
How do axial coolant channels reduce the risk of tool breakage?
Axial coolant channels feed high‑pressure coolant directly to the cutting edge, lowering thermal stress at the point of generation and flushing chips away, which together reduce flank wear and the chance of sudden tool failure when using a boring bar with internal coolant.
Can internal coolant boring bars be used on both lathes and machining centres?
Yes. The internal coolant design is compatible with standard toolholders used on lathes and machining centres, making the internal coolant boring bar a flexible choice across machine platforms.
Which workpiece materials benefit most from coolant‑fed boring bars?
Materials that produce long, continuous chips or that are prone to thermal softening during cutting—such as certain stainless steels and high‑strength alloys—benefit markedly from the chip flushing and cooling provided by a boring bar with internal coolant.
