Boring bar A12-16M — 18 mm, internal coolant (Teknik Makina)

The boring bar A12-16M for DCMT 0702 indexable inserts is designed for precise left-hand turning and internal coolant operations in production and job-shop environments

• Internal coolant for consistent tool cooling
• 18 mm cutting diameter for precise bore sizing
• 150 mm overall length with 16 mm shank diameter
• Left-hand cutting, 95° cutting angle compatibility

Consistent bore quality through defined geometry and insert compatibility

The A12-16M toolholder is engineered to deliver repeatable internal turning performance by pairing a defined 18 mm diameter with a stable tool geometry. Compatible with DCMT 0702 carbide indexable inserts, the design and the 95° cutting angle reduce radial deflection and help maintain tolerances over serial runs. This results in improved cylindricity and surface finish compared with loosely specified alternatives, translating into fewer reworks and predictable cycle times on CNC lathes and turning centres.

Controlled heat and chip evacuation for longer insert life

Built-in internal coolant directs cooling and lubrication to the cutting zone, which lowers cutting temperatures and flushes chips away from the insert pocket. That targeted coolant supply extends insert life and stabilises cutting forces, so the production process benefits from reduced thermal expansion and steadier tool engagement. For operations where built-up edge or heat-related flank wear is a concern, the internal coolant function supports higher sustained productivity and a consistent part finish.

Compact design for secure clamping and easy handling

A 16 mm shank combined with a 150 mm overall length delivers a compact package that balances reach with rigidity. The small mass (approx. 0.187 kg) shortens tool-change cycles and reduces spindle load, while the 11 mm clamping head width ensures secure insert retention. Fast, reliable assembly is achieved with the supplied Torx hardware—Torx T8 key and M2.5×5.5 screw—minimising downtime during index and insert changes and helping to maintain concentricity under operational loads.

Suitable for production turning where left-hand orientation is required

Left-hand cutting orientation is specified where the machining process or machine setup demands it; this tool’s left-hand configuration matches such setups and prevents the need for workpiece re-fixturing. The KA518TM is therefore well suited for niche turning tasks, secondary operations and retrofit tool stations where DCMT 0702 inserts are already in use. For workshops aiming to standardise tooling across multiple machines, this compact, coolant-fed toolholder offers a pragmatic balance of accessibility and machining performance.

FAQ

What insert type fits this tool?
The tool accepts DCMT 0702 indexable inserts; the holder is specified to work with that insert geometry for predictable cutting results.

Is the tool coolant-fed?
Yes — the KA518TM features internal coolant to supply lubricant directly to the cutting zone and aid chip evacuation.

Which cutting orientation does the bar support?
This holder is configured for left-hand cutting, suitable for setups that require counter-clockwise tool engagement.

What are the key mounting and fastening details?
Secure clamping is provided via the included M2.5×5.5 screw and is tightened using a Torx T8 key for repeatable insert retention.

What shank and overall dimensions should be considered for machine setup?
Important dimensions: 16 mm shank diameter and 150 mm overall length; these determine clamping requirements and reach on the machine.
