RÖHM EXTRA50-RV keyless drill chuck – 1.5–13 mm clamping, 1/2"-20 mount

The EXTRA50-RV is a compact, radial-lock keyless drill chuck designed for cordless and mains drills, offering reversible operation for right and left rotation.

• Compact 51 mm open-jaw length
• Carbide jaw chamfers for secure grip
• Radial locking in metal housing
• Impact-drill resistant with dust protection

Reduced machine head load for smoother handling

The compact construction of this keyless chuck reduces the mass at the tool head, improving balance and lowering operator fatigue during repetitive tasks. With a clamping range of 1.5–13 mm and an external diameter of 42.4 mm, the unit keeps the centre of gravity close to the spindle, which benefits both handheld and bench-mounted drilling operations. The short installed length (approx. 51 mm with jaws open) also helps when working in confined spaces or tight setups, contributing directly to faster set-ups and steadier drilling results.

Durable build for continuous workshop use

Built with a metal housing and a radial locking mechanism, the chuck withstands everyday workshop stresses. The carbide jaw chamfers deliver consistent bite on drill shanks, reducing slippage under load and preserving concentricity over time. The design includes impact-drill resistance and dust protection, features that extend service life where dust and hammering actions are present. Through-drilled construction allows for easy bit cleaning or lubrication without disassembly, supporting lower maintenance intervals and greater uptime.

Universal compatibility and fast tool changes

Fitted with a 1/2"-20 mounting thread, the chuck mates with standard arbors and many handheld spindles, enabling quick integration into existing tool fleets. Support for right and left rotation makes it suitable for screwdriving reversals and applications requiring counter-rotation. The keyless mechanism delivers rapid bit changes, reducing downtime during production or repair tasks and improving overall workflow efficiency. For workshops that value adaptability, the chuck's compactness and robust jaw geometry ensure reliable performance across a wide range of drilling and fastening operations.

FAQ

Is the EXTRA50-RV compatible with standard drill spindles?
The RÖHM EXTRA50-RV keyless drill chuck uses a 1/2"-20 mount and is compatible with spindles and arbors that accept that thread, enabling straightforward retrofitting in many workshop setups.

What bit diameters can be used with this chuck?
The chuck clamps twist drills and similar shanks in the 1.5–13 mm range, covering a broad spectrum of common drilling and fastening sizes.

Can the chuck be used with hammer or impact drilling?
Yes, the design states impact-drill resistant construction; combined with the metal housing and dust protection this makes the chuck suitable for demanding conditions where occasional hammer action occurs.

How does the radial locking benefit workshop safety?
Radial locking secures the jaws under torque, improving bit retention and reducing the risk of slippage; the carbide jaw chamfers further enhance stable clamping during high-load operations.

Is the chuck suitable for reversible applications?
The EXTRA50-RV supports right and left rotation, so it is suitable for operations that require reversible turning, such as screw extraction or certain tapping tasks.
