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.

Solid carbide body for high rigidity Internal coolant for improved chip evacuation Compatible with CCMT 09T3 indexable inserts 25 mm diameter, 250 mm overall length Increased stiffness for repeatable turning quality The monolithic solid carbide construction provides high bending resistance and dimensional stability during heavy engagement, which reduces vibration and improves surface finish. In practical terms, the robust design keeps the tool tip position consistent across repeated operations, so tolerance adherence becomes easier to achieve. For shops that require predictable results, the combination of diameter and rigidity translates directly into fewer reworks and steadier cycle times. Controlled cooling and chip evacuation for safer cycles The integrated internal coolant channel directs fluid to the cutting zone, aiding in heat dissipation and chip removal. This targeted cooling decreases thermal load on the insert and workpiece, supporting longer insert life and more consistent cutting conditions. For operators unfamiliar with internal coolant systems: it means coolant exits near the cutting edge rather than only from the machine spindle, improving lubrication where it matters and reducing the risk of built‑up edge. Simple matching with common indexable inserts and holders Designed for use with CCMT 09T3 indexable inserts, the tool accepts widely available carbide plates, which keeps spare parts standardised across the workshop. The shank is specified as shank Ø20 mm, and the overall dimensions — Ø25 mm cutting body and 250 mm length — suit many turning and boring setups. The ISO designation E20S SCLCL 09 indicates the geometry and clamping style for compatibility checks when selecting toolholders; when fitting the bar, ensure the holder matches the stated shank diameter and clamping method. Practical handling and maintenance for production environments The assembly uses a Torx fastening system (Torx key T15 with screw M3.5x8.5) for secure insert clamping and straightforward servicing. The cutting height 13 mm provides a clear datum for insert seating and repeatable indexation. Routine maintenance focuses on cleaning the coolant channel and checking the clamping screw torque to preserve seating accuracy. Proper care maintains machining stability and helps to maximise the return on investment from the tool’s durable carbide construction.

The tool’s 25 mm diameter and the 200 mm overall length are balanced to provide reach without sacrificing stability, making the bar suitable for a broad range of turning tasks where consistent concentricity is required. Flexible insert compatibility for lower tooling costs Designed for use with CC-- 09T3 indexable inserts, the boring bar enables rapid insert changes and compatibility with commonly available insert grades. Using indexable cutting tips minimises downtime for regrinding and supports a predictable tooling budget: worn inserts can be replaced in seconds rather than replacing the whole tool. The 95° cutting angle provides a secure seating geometry for the insert, ensuring reliable chip control and extended insert life when paired with appropriate grades for the workpiece material. Efficient setup and predictable handling in the workshop The bar’s ISO designation S25R SCLCR simplifies selection and toolholder matching in CNC tool magazines and manual toolposts. The specified cutting height 40 mm and the shank sizing ensure compatibility with standard clamping systems, while the right-hand cutting direction matches common turning cycles. At a weight of 0.694 kg, the assembly is easy to handle during setup, yet substantial enough to maintain a solid cutting stance. These dimensions contribute to faster set-ups and fewer adjustments between jobs. Practical benefits for production and maintenance Using a standardised boring bar like this one reduces complexity across tool inventories: a single shank and insert system supports multiple diameters and operations. The ability to fit indexable inserts means that different grades can be selected for aluminium, steel or harder alloys (subject to insert grade selection), offering process flexibility without changing the basic tool. Overall, the bar is an efficient, serviceable solution for shops focused on throughput and consistent component quality.

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.
