KA217TM A20Q – 25 mm boring bar with internal coolant (Teknik Makina)

KA217TM A20Q is a compact boring bar engineered for precision internal turning where coolant supply to the cutting edge and reliable clamping are essential.

• 25 mm cutting diameter for medium bores
• Integrated internal coolant for efficient chip removal
• 180 mm overall length for reach in confined setups
• 20 mm shank for secure clamping

Consistent bore quality through rigid design

The combination of a 25 mm outer diameter and a 20 mm shank provides a stable toolholder interface that helps reduce chatter and run-out. A longer reach at 180 mm overall length allows access into deeper bores without sacrificing rigidity. The ISO designation A20Q denotes a standardised geometry that simplifies tool selection in production environments, while the compact mass of 0.422 kg aids manoeuvrability during set-up and minimises spindle load where required.

Coolant delivery that protects the insert and improves cycle time

The built-in internal coolant channel delivers cutting fluid directly to the cutting zone, which reduces tempering and clears chips efficiently. This targeted lubrication supports longer insert life and lowers the risk of built-up edge, contributing to more consistent surface finishes and potentially shorter downstream finishing operations. Combined with a 107.5° cutting angle, the configuration favours stable chip formation on right-hand cuts and can improve process reliability in repetitive turning cycles.

Fast maintenance and secure clamping for uninterrupted production

Designed with practical service in mind, the tool uses a Torx T8 key and M2.5x6.5 Torx screw for secure fastening of the adjustable clamping components. The 13 mm clamping width and 30 mm cutting height parameters indicate a robust seating for the cutting geometry, making insert changes straightforward and repeatable. The SKU KA217TM is referenceable for spare parts and ordering, enabling fast replacement of wear items with minimal downtime.

Built for workshops and high-mix manufacturing

The tool’s right-hand cutting direction and compact footprint make it versatile for both small jobbing shops and larger production cells where space and tool interchangeability matter. Sourcing through Metav Werkzeuge ensures access to a wide stock range and the regional logistics that help maintain a steady supply to European workbenches. If clarification on fitment or machine compatibility is needed, technical consultation is available to match the boring bar to the intended turning set-up.

FAQ

What is the primary benefit of the internal coolant on this boring bar?
The internal coolant on the KA217TM A20Q supplies fluid directly to the cutting zone, improving chip evacuation and reducing thermal load on the cutting edge for more consistent tool life.

Which clamping specifications are relevant when replacing the cutting components?
Clamping is configured around a 13 mm clamping width with a Torx T8 fastening system using an M2.5x6.5 screw; these values are integral to safe and repeatable insert changes on the KA217TM.

Is the KA217TM suitable for deep-reaching internal turning operations?
With an overall length of 180 mm and a 25 mm diameter, the tool provides extended reach while maintaining a 20 mm shank for reliable clamping in many internal turning scenarios.
