50mm Quick-Change Drill Chuck 1-13mm B16 Right-Hand Accuracy Self-Tightening Hardened Parts - RÖHM

Take advantage of the combination of accuracy-grade construction, self-tightening operation, and hardened wear parts for consistently concentric results in high-speed drilling; order or request specification advice via Metav Werkzeuge if required.

Spiro quick-action drill chuck 1–13 mm (B16) — accuracy-grade, self-tightening chuck by RÖHM

The Spiro quick-action drill chuck 1–13 mm (B16) is an accuracy execution, self-tightening chuck engineered for right-hand rotation applications on drilling machines and boring mills

• Accuracy-grade, self-tightening design
• Clamping range 1–13 mm
• Hardened wear parts for longevity
• B16 cone shank, right-hand rotation

Consistent concentricity for precision machining

The accuracy execution of this clamping system ensures stable concentricity when holding small to medium tools, which reduces run-out and improves hole quality. Built as a precision variant, the chuck combines a 1–13 mm clamping range with a finely finished jaw interface so that radial deviation is minimised during spindle rotation. Because the mechanism is self-tightening, tightening effort is maintained automatically during operation, translating into repeatable hole positions and reduced scrap rates in component production.

Built for continuous high-speed operation

All moving and wearing components are hardened, which extends service life under continuous use and limits dimensional drift. The design includes a continuous, self-acting re-tightening function that keeps the tool seated securely at elevated speeds; this feature is particularly beneficial for high-speed drilling tasks where thermal and centrifugal forces can otherwise loosen conventional chucks. The chuck’s suitability for precision work on drilling machines and boring mills means it is specified where speed and accuracy must coexist.

Compatibility, handling and maintenance benefits

Equipped with a B16 cone shank, the chuck fits compatible machine spindles with a secure taper connection and an outer diameter of 50 mm, providing compact clearance in machine heads. The keyless, self-clamping principle removes the need for an external key while also reducing handling time during tool changes, which improves workflow efficiency on the shop floor. Routine maintenance is simplified: thanks to the hardened wear parts and the self-tightening mechanism, inspection intervals can be extended and downtime reduced, supporting reliable production scheduling.

FAQ

What clamping range does the chuck cover?
The RÖHM Spiro quick-action drill chuck (article 4000832069NW) provides a clamping range of 1–13 mm, suitable for a wide variety of twist drills and similar tooling.

Is this chuck suitable for high-speed drilling?
Yes — the design includes continuous self-acting re-tightening and hardened wear parts, which make the chuck appropriate for high-speed drilling and precision operations on drilling machines and boring mills.

Can the chuck be fitted to a standard B16 spindle?
Yes — the chuck is supplied with a B16 cone shank, intended for direct mounting into compatible machine spindles with a matching taper.

How does the self-tightening mechanism benefit workshop productivity?
The self-tightening function maintains clamping force automatically during rotation, reducing tool slippage and changeover time; this supports consistent hole quality and fewer interruptions on the production line.

What maintenance is required to keep the chuck performing accurately?
Maintenance is minimal: periodic cleaning and inspection of the jaws and taper are recommended. The hardened wear parts and self-tightening feature reduce wear rates and extend service intervals.
