BEYOND DCMT Boring Bars – Internal Turning Toolholder Series

The BEYOND DC INSERT boring bar series is designed for precision internal turning and boring operations using DCMT carbide inserts. This series includes a full range of ISO-standard toolholders: SDWCR/L, SDZCR/L, SDXCR/L, SDUCR/L, and SDQCR/L. The holders deliver high rigidity, stable clamping, and excellent chip control for steel, stainless steel, alloy steel, and cast iron machining.

Supported Toolholder Families

• SDWCR / SDWCL – Screw-only clamping, high repeatability, low vibration.
• SDZCR / SDZCL – Reinforced shank structure for heavy-duty boring.
• SDXCR / SDXCL – Positive rake geometry for smooth cutting and small-diameter bores.
• SDUCR / SDUCL – Multi-functional boring bar for profiling and facing.
• SDQCR / SDQCL – High-stability clamps for precision finishing.

Key Features

• Compatible with DCMT0702 / DCMT11T3 / DCMT32.51 inserts.
• ISO turning holder design for reliable tool life and dimensional accuracy.
• High-rigidity steel construction with anti-vibration performance.
