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.

S50U DCLNL boring bar — left‑hand indexable tool for CN-- 1204 inserts by Teknik Makina The S50U DCLNL boring bar is a left‑hand tool holder designed for robust internal turning with CN-- 1204 indexable inserts, suitable for demanding lathe or CNC operations where stability and repeatable results are required. Left‑hand cutting for specialised turning operations Compatible with CN-- 1204 insert format Sturdy 50 mm shank for enhanced rigidity 350 mm overall length for deep boring Stable performance through optimised tool geometry The S50U DCLNL was developed to deliver consistent metal removal where rigidity and vibration damping are decisive for finish and tool life. With a 50 mm shank and a body diameter 63 mm, the holder reduces deflection on longer overhangs and supports heavier cuts without compromising accuracy. The combination of mass and geometry—reflected in the listed weight 5.166 kg and a cutting angle 95°—improves tool stability, which in turn optimises cycle times and extends the service interval for inserts and clamping components. This approach targets measurable productivity gains in serial production environments. Straightforward integration and predictable insert behaviour Compatibility with standard indexable formats simplifies tooling management and reduces changeover time. The holder accepts CN-- 1204 inserts and ensures a controlled chip flow thanks to the specified geometry and cutting height 60 mm, which secures the insert seat and repeatability after re‑indexing. The left‑hand orientation supports machining strategies that require counter‑direction turning or specific approach angles on CNC lathes. For workshops standardising on indexable tooling, the result is fewer inventory variants and more predictable process windows. Quick setup, reliable clamping and lower downtime Designed for practical workshop use, the bar features a clear clamp specification (designation 12) and an ISO designation that indicates familiar mounting and handling routines. The precise clamp interface and robust construction reduce the need for frequent torque checks and rework, which helps maintain uptime on the machine. When paired with consistent tool‑holder handling and regular inspection, the S50U DCLNL supports stable tolerance adherence and fewer scrap parts, contributing to a leaner production flow and predictable throughput.

Order the boring bar directly via Metav Werkzeuge or ask our consultants if needed. Boring bar SCLC for CC-- indexable inserts (S06H SCLCR, Teknik Makina) — Ø6 mm, 100 mm overall length A boring bar SCLC for CC-- indexable inserts intended for right‑hand internal turning, optimised for compact bores and reliable insert seating Compact Ø6 mm body for tight bores Compatible with CC-- 0301 indexable inserts 95° cutting angle for precise internal profiling Shaft Ø8 mm for secure clamping Accurate internal machining with a compact profile The compact Ø6 mm tool body is designed for machining confined internal diameters where rigid control is required. With an overall length of 100 mm and a short exposed section, vibration is reduced and repeatability is improved; this results in better bore roundness and surface finish. The small diameter does not compromise stability when clamped correctly against a shaft Ø8 mm, so consistent machining results can be achieved even in narrow bores. Stable clamping and proven insert interface Compatibility with CC-- 0301 indexable inserts gives flexibility in edge geometry and grade selection. The S06H SCLCR mounting form is engineered for reliable insert seating and positive clamping, which lowers the risk of insert movement under cutting loads. The 95° cutting angle supports controlled chip flow and stable cutting forces, translating into longer insert life and predictable tool performance for series production. Efficient setup and straightforward application The right‑hand cutting direction and standard ISO designation simplify integration into existing toolholders and set‑ups. With a cutting height 18 mm and low overall weight (approx. 0.048 kg), the tool is easy to handle during tool changes and reduces operator effort without sacrificing rigidity. Clear compatibility with a common insert size reduces inventory complexity and speeds up changeovers in multi‑machine environments. Engineered for dependable production results Manufactured to industrial tolerances and intended for internal turning operations, this tool supports process stability and repeatable outcomes. The combination of compact diameter, secure clamping and a standard insert interface provides a cost‑effective solution for workshops requiring precision inside turns. Selection of the appropriate insert grade will determine achievable surface finish and tool life under the given machining conditions.

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.
