KA258TM boring bar (A16Q SDUCL) by Teknik Makina — left-hand, internal coolant

The KA258TM is a left-hand boring bar designed for precision internal machining with DC-- style indexable inserts, offering compact shank geometry and coolant-through capability for productive tool life.

• A16Q SDUCL shank format
• For DC-- 11T3 indexable inserts
• Internal coolant supply integrated
• Left-hand cutting, 180 mm overall length

Stable internal machining with coolant-fed cutting

The bar is engineered to provide consistent stability in internal turning operations by combining a compact 16 mm shank with a Ø20 mm cutting head and an overall length of 180 mm. The internal coolant channel supplies cutting fluid directly to the cutting edge, which improves chip evacuation and reduces thermal load on the insert. This results in more reliable tool life and a finer surface finish, particularly where access is restricted and vibration must be minimised. The solid construction and modest weight (0.285 kg) support quicker spindle acceleration and controlled dynamic behaviour during interrupted cuts.

Compatibility and quick toolset integration

Designed to accept DC-- 11T3 style inserts, the tool follows the ISO-style designation A16Q SDUCL, ensuring straightforward integration with familiar clamping systems. The specified clamping holder compatibility value 07 guides selection of the correct holder for secure fixation. The standardised interface and indexable inserts use mean tool changes and reconditioning are fast, reducing downtime in a mixed production environment. Left-hand rotation is provided for applications that require reverse approach or specific fixture orientations, and the 93° cutting angle supports effective shear formation for common turning tasks.

Practical benefits for workshop reliability and productivity

With a cutting height of 30 mm and a design tuned for efficient chip control, the tool permits precise depth engagement while maintaining predictable cutting forces. The relatively light tool mass eases manual handling and machine setup, while the internal coolant lowers flank wear and helps avoid built-up edge formation. For procurement, the combination of a standardised ISO designation and widely used insert form factor delivers cost-effective stocking and simple replenishment. As a trusted supplier, Metav Werkzeuge provides a quality-controlled supply channel to European workshops, backed by decades of distribution experience and a broad product range to reduce supplier complexity.

FAQ

Which insert type fits this boring bar?
The bar accepts DC-- 11T3 style indexable inserts; the KA258TM follows the A16Q SDUCL interface for reliable clamping.

Is the coolant supplied through the tool?
Yes — the KA258TM features internal coolant delivery to the cutting edge for improved chip control and reduced tool wear.

What shank size is required for the holder?
Use a holder compatible with a 16 mm shank; the ISO designation A16Q SDUCL clarifies the mounting geometry for the KA258TM.

Can this tool be used for reverse cutting directions?
The tool is a left-hand cutting bar and is intended for applications where left-hand rotation or approach is required.

What are the key dimensions to check before fitting?
Confirm the shank diameter (16 mm), overall length (180 mm) and the cutting diameter (20 mm) for correct fitment and reach.
