18mm A12K SDUCL Tool Holder With Internal Coolant, 93° Cutting Angle - Teknik Makina

Benefit from a compact, precision‑oriented boring solution that combines internal coolant for reliable chip evacuation with compatibility for SDUC indexable inserts; order the KA252TM via Metav Werkzeuge or consult our specialists for suitability and delivery.

KA252TM Boring Bar (A12K SDUCL) — SDUC for DC-- Indexable Inserts, Left‑hand

The KA252TM boring bar is a left‑hand turning tool designed for secure insert clamping and controlled chip flow in medium‑duty CNC turning applications.

• Robust left‑hand cutting orientation
• Internal coolant for chip evacuation
• Compatible with DC-- 0702 SDUC inserts
• 16 mm shank, 180 mm overall length

Consistent chip control for longer tool life

The boring bar employs internal coolant directed to the cutting edge to improve chip evacuation and thermal control during interrupted or continuous cuts. With a 93° cutting angle, the geometry reduces radial cutting forces and diminishes vibration, which prolongs insert life and stabilises component tolerances. This pragmatic setup translates into fewer tool changes and more predictable cycle times on production runs.

Predictable performance through standardised inserts

Designed for the SDUC style of tooling and optimised for DC-- 0702 indexable inserts, the tool supports quick insert replacement and consistent cutting geometry. The standardised insert interface simplifies tooling logistics and reduces setup time on the machine. For operations where repeatability matters, the combination of SDUC mounting and standard insert sizes ensures uniform cutting behaviour across batches.

Compact mounting with precise clamping for tight spaces

The bar’s 16 mm shank and 180 mm overall length offer a compact footprint for applications with restricted overhang, while the raised cutting height of 40 mm provides reliable contact with the insert corner. The assembly’s low mass (0.267 kg) reduces centrifugal forces at higher spindle speeds and the specified clamp size 07 delivers a secure seat for the insert, maintaining concentricity and reducing runout risk. This compact configuration is suited to both prototype work and small‑batch production where accessibility and stiffness are essential.
