25mm Boring Bar A20Q 180mm With Internal Coolant, Right-Hand 93° Cutting Angle - Teknik Makina

Take advantage of the combination of internal coolant, a 25 mm cutting diameter and a compact 180 mm overall length for stable, repeatable boring cycles; order the bar directly via Metav Werkzeuge or consult the technical team for process integration.

Boring bar A20Q — 25 mm, internal coolant — Teknik Makina

The Boring bar A20Q is a precision tool for internal cooling-assisted boring applications in machining environments where stable bore geometry and efficient chip evacuation are required.

• 25 mm cutting diameter
• Internal coolant supply
• Overall length 180 mm
• Right-hand cutting direction

Consistent bore geometry through rigid dimensions and angle control

The A20Q boring bar is dimensioned to provide stable cutting conditions: a 25 mm cutting diameter combined with a shank diameter 20 mm offers a balance between reach and stiffness for routine bore finishing. The tool’s cutting angle 93° and a cutting height of 32 mm ensure predictable engagement with the insert edge, which in turn reduces vibration and improves surface consistency. Engineers benefit from fewer rework cycles and machines spend more time producing acceptable parts.

Improved thermal management with internal coolant

An integrated internal coolant channel delivers cutting fluid directly to the cutting zone, which reduces tool-tip temperature and improves lubricity at the insert rake face. This targeted cooling lowers thermal expansion of both tool and workpiece, helping to keep tolerances within specification during longer cutting periods. The coolant provision also assists chip control, decreasing the risk of built-up edge and promoting longer, more reliable tool life.

Workshop compatibility and straightforward assembly

Designed to common workshop practices, the bar carries an ISO designation A20Q and uses standard screw fixing: Torx T8 for assembly and Torx screw M2.5x6.5 for secure clamping of small components. A clamping head width of 13 mm supports compact clamping systems and facilitates quick replacement routines. The design reduces process downtime and makes the bar easy to integrate into existing toolholders and machining sequences.

Production-ready dimensions and handling

With an overall length of 180 mm and a weight of 0.69 kg, the bar offers practical handling without compromising on rigidity. The right-hand cutting direction is suited to typical spindle rotations and machining set-ups, allowing the tool to be used in conventional boring cycles. The compact footprint aids in multi-axis operations where clearance is limited, while the balanced geometry supports repeatable set-up and measurement routines at the machine.

FAQ

What materials is this boring bar suited for?
The A20Q boring bar is specified for general machining tasks; material suitability depends on the chosen insert and cutting data, and the A20Q from Teknik Makina is commonly applied where internal coolant and medium stiffness are required.

How is coolant delivered to the cutting edge?
Coolant is supplied internally through the bar’s coolant channel, ensuring direct delivery to the cutting zone for the A20Q boring bar (SKU KA207TM), which improves temperature control and chip evacuation.

Which clamping interface does the bar require?
The bar features a 13 mm clamping head width and uses a Torx T8 engagement with Torx screw M2.5x6.5 for securing auxiliary components and accessories.

Is the A20Q suitable for long-reach boring?
With an overall length of 180 mm and a shank diameter of 20 mm, the A20Q provides a compromise between reach and rigidity; for extended reach operations, consider bar stiffness versus required tolerance before selection.
