3-16mm Precision Self-Tightening Keyless Drill Chuck B18, Hardened Components - RÖHM

Take advantage of the combination of accuracy-grade construction, self-tightening operation and hardened wear parts for reliable, high-speed drilling and sustained concentricity in production. Order the RÖHM component directly via Metav Werkzeuge or ask the consultants for compatibility advice for specific machines.

RÖHM Spiro keyless drill chuck (B18, 3–16 mm clamping range)

The RÖHM Spiro keyless drill chuck is an accuracy-grade, self-tightening chuck designed for high-speed and precision drilling on drill presses and drilling machines.

• Accuracy execution for precision work
• Self-tightening with constant re-tension
• Hardened wear parts for extended service life
• B18 taper, suitable for right-hand rotation

Precision and reliability for production work

The accuracy-grade design delivers consistent concentricity, making this chuck a dependable choice for tasks that demand tight tolerances. The combination of a 3–16 mm clamping range and a compact outer diameter of 55 mm supports versatile tooling without compromising stability. The integrated B18 taper provides a secure mounting to standard spindles, while the right-hand rotation configuration suits typical drilling stations. This results in reduced rework and a smoother workflow in serial production.

Low maintenance and high operational uptime

Equipped with hardened wear parts and a continuous automatic re-tension mechanism, the chuck sustains clamping force under load and at elevated speeds. The self-tightening action increases grip security during operation, lowering the risk of tool slippage and improving safety. For maintenance planning, the hardened components mean longer intervals between part replacement and predictable life cycles, which supports efficient machine scheduling and cost forecasting.

Practical benefits for workshop and industrial use

Compact yet robust, the chuck is tailored for precision drilling tasks on drill presses, radial drilling machines and similar equipment. The small footprint and 55 mm outer diameter allow use on machines with limited spindle clearance, while still accepting a broad range of drill shank sizes. For operations prioritising both speed and accuracy, the combination of self-tightening behaviour and hardened components provides a reliable solution that minimises downtime and maintains hole quality across batches.
