Take advantage of a rigid, ISO‑specified holder with internal coolant and precise compatibility for DC-- 11T3 indexable inserts to keep cycle times predictable and tool changes fast; order the boring bar directly via Metav Werkzeuge or ask our consultants if technical advice is required.

KA148TM Boring Bar A20Q SDQCR — 20 mm Shank, Internal Coolant (Teknik Makina)

A KA148TM is a coolant-fed boring bar designed for stable internal turning with DC-- 11T3 indexable inserts in precision workshop and light-production environments

• Right-hand cutting orientation
• Internal coolant supply
• 20 mm shank diameter
• Compatible with DC-- 11T3 inserts

Stable cutting and repeatable accuracy for production runs

The holder is engineered to deliver consistent concentricity, which reduces scrap and rework in batch machining. The A20Q SDQCR designation denotes an established ISO form factor that eases integration with existing toolholders and turret systems. With a solid 20 mm shank and a 25 mm body diameter, the assembly maintains rigidity under cutting loads, translating the bar’s geometry into predictable surface finish and hole tolerances — a tangible time‑saving for repetitive internal turning tasks.

Effective cooling and chip control for longer insert life

Built‑in internal coolant directs fluid to the cutting zone, improving heat dissipation and aiding chip evacuation. Combined with the 107.5° cutting angle, this encourages favourable chip flow and reduces thermal wear on the insert rake. The result is extended tool life for the indexable inserts and fewer unscheduled tool changes, which supports higher uptime and lower tooling cost per component over extended production periods.

Compatibility that simplifies tooling logistics

Designed for DC-- 11T3 indexable inserts and referenced as A20Q SDQCR, the boring bar suits common insert sizes and clamping systems used in many workshops. The right‑hand cut orientation is standard for most lathe and turret applications, making the component straightforward to specify across multiple machines. This compatibility reduces the need for bespoke holders and shortens procurement cycles when replacing or upgrading toolsets.

Practical dimensions and workshop handling

With an overall length of 180 mm and a cutting height of 32 mm, the bar balances reach and stiffness for typical internal turning depths. At 0.425 kg, the unit is light enough for easy handling during set-up yet robust in service. These tangible measurements help production planners and setup personnel assess clearances and tool overhang in CAM programming or manual setup without additional measuring steps.

Integration, maintenance and supply assurance

The bar’s proven form factor and coolant provision simplify maintenance routines: access to the coolant channel is standardised and insert replacement follows established clamping practice. Choosing an ISO‑specified holder reduces training time for operators and aligns with inventory management best practice. Combined with Metav’s supply reliability from Emmerich, the product supports continuous operation rather than intermittent tooling shortages.
