Boring Bar KA208TM — A25R SVUBR, 93° geometry with internal coolant (Teknik Makina)

The Boring Bar KA208TM is a right‑hand indexable‑insert boring bar designed for precision internal turning and coolant‑assisted machining.

• 93° cutting angle for stable boring
• Internal coolant for enhanced chip evacuation
• 25 mm shank diameter for secure clamping
• 200 mm overall length for deep bore reach

Stable geometry for repeatable results

The 93° cutting angle provides a near‑radial engagement that reduces deflection during machining and supports consistent bore form. By favouring rigidity over aggressive overhang, this geometry helps maintain dimensional accuracy in serial production. The bar’s ISO designation A25R SVUBR identifies it as a right‑hand, indexable‑insert boring tool, which simplifies setup and interchangeability in standard toolholders.

Efficient chip control and cooling

Equipped with internal coolant, the boring bar channels cutting fluid directly to the cutting zone, improving lubrication and assisting with chip evacuation. This reduces heat buildup at the insert edge and helps preserve tool life while lowering the risk of built‑up edge. For processes where coolant access is critical, the internal feed supports more stable cutting and fewer interruptions for manual cleaning.

Secure clamping and practical dimensions

A 25 mm shank diameter ensures a firm and concentric hold in compatible toolholders, reducing vibration and improving surface finish. With a 200 mm overall length, the bar reaches deeper bores without excessive overhang, striking a balance between accessibility and stiffness. The unit’s weight (0.723 kg) reflects a robust construction suitable for industrial workshop environments.

Designed for indexable inserts and easy maintenance

The holder accepts indexable inserts and features a cutting height of 40 mm, enabling straightforward insert seating and replacement. Using indexable grades simplifies maintenance: worn edges can be rotated or replaced quickly, minimising downtime and supporting a predictable production flow. The right‑hand cutting direction is standard for many turning operations and is compatible with most conventional setups.

FAQ

What type of inserts does this boring bar accept?
The KA208TM is specified for use with VBMT indexable inserts, utilising the SVUB holder style for secure seating and straightforward insert changes.

Is the coolant supplied through the boring bar?
Yes, the KA208TM features internal coolant, which delivers fluid directly to the cutting edge to aid lubrication and chip removal.

Which cutting direction is supported by the bar?
The tool is configured for right‑hand cutting, as indicated by the ISO code and the tool’s geometry.

How does the 93° cutting angle affect machining?
A 93° cutting angle increases stability and reduces radial deflection, improving bore accuracy and repeatability in production runs.

What are the key dimensions for clamping and reach?
Clamping is accommodated by a 25 mm shank diameter, while the bar offers a 200 mm overall length for deeper bore access without excessive overhang.
