RÖHM Supra S Keyless Drill Chuck 3.0–16 mm, 1/2"-20

The RÖHM Supra S is a light-duty, self-tightening keyless drill chuck designed for right-hand rotation and intended for workshop and maintenance drills

• Self-tightening operation for secure hold
• Clamping range 3.0–16 mm
• 1/2"-20 threaded mount
• Light-duty construction, 46 mm outer diameter

Precision hold for consistent drilling results

A wide clamping range of 3.0–16 mm enables use with a variety of drill bits and accessories without repeated chuck changes. The self-tightening mechanism increases axial grip as torque rises, which reduces slippage under load and improves hole quality; this technical behaviour makes the chuck particularly effective for repetitive, medium-duty applications. The result is fewer interruptions and a more predictable process flow in everyday workshop operations.

Fast installation and spindle compatibility

The chuck mounts via a 1/2"-20 internal thread, a common interface for many hand-held and light bench drills, which simplifies retrofitting and reduces downtime when replacing worn or unsuitable chucks. Specified for right-hand rotation, the assembly matches standard drilling directions and avoids unintended reverse loading. Clear interface standards mean compatibility checks are straightforward and integration into existing tooling setups is efficient.

Compact form and straightforward maintenance

With an outer diameter of 46 mm, the chuck offers a compact footprint that suits confined toolheads and handheld devices while still providing a robust grip surface. The light-duty classification keeps mass low for easier handling and faster bit changes, which benefits frequent tool swaps. Basic care—regular cleaning of the jaws and lubrication of the screw thread—preserves performance and extends service life without complex maintenance procedures.

Best uses and application fit

Engineered for workshops, maintenance teams and small-scale production environments, this keyless chuck supports common drilling tasks where reliability and quick tool changes matter most. Its design balances convenience and functional grip, making it well suited to repair jobs, assembly work and general fabrication where heavy-duty industrial chucks are not required. The chuck delivers practical benefits for workshop workflows and helps keep operations moving smoothly.

FAQ

What clamping range does the chuck cover?
The chuck covers a 3.0–16 mm clamping range, which permits use with a broad selection of common drill bits and small accessories.

Is the mount compatible with standard drill spindles?
Yes, the chuck uses a 1/2"-20 internal thread mount, making it compatible with many hand-held and light bench spindles that accept this standard.

Can this chuck be used on reversible drills?
The construction is specified for right-hand rotation; use on reversible machines should respect this direction to ensure the self-tightening behaviour remains effective.

How does the self-tightening feature improve performance?
The self-tightening action increases jaw grip with applied torque, reducing the risk of slippage and improving drilling consistency during medium-duty tasks.

Is the Supra S suitable for heavy industrial use?
The Supra S is a light-duty keyless chuck optimised for workshops and maintenance work rather than heavy industrial machining that demands specialised heavy-duty chucks.
