RÖHM Supra S quick‑change drill chuck — 0.5–10 mm clamping, 1/2"-20 thread

The RÖHM Supra S is a light‑duty, self‑tightening quick‑change drill chuck designed for right‑hand rotation, providing a compact and efficient solution for workshop and production drilling applications.

• Self‑tightening mechanism for safer clamping
• Clamping range 0.5–10 mm
• 1/2"-20 spindle thread, internal mounting
• Compact diameter Ø 35.8 mm, light‑duty design

Secure clamping for consistent drilling results

The self‑tightening mechanism converts rotational torque into additional jaw clamping force, delivering a firmer hold during clockwise rotation. With a clamping range of 0.5–10 mm, the chuck accommodates a broad spectrum of small drills and accessories, reducing tool changeovers and downtime. This functional principle makes the chuck particularly suitable for repetitive drilling tasks where consistent concentricity and retention are essential. The benefit is fewer re‑clamps and more predictable hole quality on standard workshop materials.

Compact spindle interface for fast integration

A standard 1/2"-20 internal thread allows straightforward mounting to many drill spindles and adaptors commonly used in bench and portable machines. The compact outside diameter of Ø 35.8 mm keeps the tool envelope small, aiding access in confined setups and improving visibility at the workpiece. Reduced overhang supports better rigidity and helps to lower runout, which in turn extends the life of small‑diameter drills and minimises scrap rates on production runs.

Light‑duty construction geared to everyday use

The light‑weight construction suits general workshop and assembly‑line operations where ease of handling and quick tool changes are priorities. As a quick‑change chuck, it removes the need for a tightening key in many applications: the self‑tightening action secures tooling during rotation, while hand‑tightening during setup simplifies workflow. This design supports faster cycle times and less operator fatigue during frequent bit swaps, offering a practical balance between convenience and secure clamping.

Practical maintenance and installation notes

Installation requires the 1/2"-20 internal thread to match the spindle adaptor or machine arbor; correct mounting torque ensures axial alignment and longevity. Regular cleaning of the jaw slots and light lubrication of moving parts will maintain performance and reduce wear. For machines that run counterclockwise or require keyed torque beyond self‑tightening limits, selection of an alternative mounting or a keyed chuck may be appropriate. Technical advisors can recommend the optimal configuration for specific applications.

FAQ

Is the chuck suitable for keyless operation only?
The RÖHM Supra S quick‑change drill chuck uses a self‑tightening principle and can be operated without a key for many routine drilling tasks; hand tightening during setup plus rotation secures the tool.

What spindle connection is required to fit this chuck?
The chuck mounts via a 1/2"-20 internal thread; ensure the machine spindle or adaptor has the matching 1/2"-20 male thread for correct installation.

Which drill sizes are supported by the chuck?
The clamping range covers 0.5–10 mm, making it suitable for small‑diameter drills and general workshop accessories within that span.

Can the chuck be used for left‑hand rotation?
The Supra S is specified for right‑hand rotation; use on machines with counter‑rotation is not recommended without confirming suitability with technical advisors.

How should the chuck be maintained to ensure long life?
Keep jaw slots clean, apply light lubrication to moving parts periodically and verify mounting tightness; these steps preserve clamping accuracy and extend service intervals.
