S50W CKUNR Boring Bar (CKUNR for KNUX Indexable Inserts) – 50 mm Shank, 450 mm Length | Teknik Makina

The S50W CKUNR boring bar is a right-hand, indexable-insert toolholder designed for internal turning and boring with KNUX 1604 inserts, offering stable cutting at a 93° engagement angle.

• 50 mm shank for stable clamping
• Compatible with KNUX 1604 inserts
• Right-hand, 93° cutting geometry
• 450 mm overall length for extended reach

Maximise material removal with proven insert compatibility

This toolholder is engineered for throughput: the CKUNR interface accepts standard KNUX 1604 indexable inserts, which simplifies inventory and speeds up insert changes. With a defined 93° cutting angle, the geometry promotes predictable cutting forces and improved chip evacuation, translating into shorter cycle times and fewer reworks. The combination of standardised inserts and robust interface reduces setup complexity and supports high-volume turning applications where repeatable performance matters.

Stable clamping and vibration resistance for precise bores

A 50 mm shank and solid construction provide rigidity that directly benefits bore quality. With a 63 mm tool diameter and 60 mm cutting height, the toolholder minimises deflection during heavy cuts, helping to maintain concentricity and surface finish. The right-hand cutting direction is matched to conventional machine spindle rotations, ensuring reliable chip flow. These mechanical attributes make the bar suitable for demanding workshop environments where consistent tolerances are required.

Ready for workshop integration and straightforward tool management

At 450 mm overall length, the bar reaches deeper bores while the modest 0.408 kg weight keeps handling safe during changeovers. The ISO designation S50W CKUNR identifies the toolholder for CAM programming and tool lists, aiding process planners and purchasing. Using established insert formats reduces toolholder proliferation and supports a lean tooling strategy; this results in fewer stocked items and clearer maintenance processes. The outcome is a practical balance between reach, stiffness and compatibility for industrial turning tasks.
