Supra SK – Self-tightening quick-change drill chuck, 1–13 mm, B12 (RÖHM)

The Supra SK is a self-tightening quick-change drill chuck with a B12 mount designed for both right- and left-hand rotation, engineered for workshop and industrial drilling tasks where fast tool changes and reliable clamping are essential

• Self-tightening quick-change mechanism
• Clamping range 1–13 mm
• B12 mount for secure attachment
• For right- and left-hand rotation
• Clamping-force safeguard for hammer drills

Faster tool changes and consistent clamping for uninterrupted production

The self-tightening mechanism provides rapid tool exchange while maintaining a reliable clamping force, which reduces machine downtime and speeds up batch processing. Because the chuck grips automatically during spindle rotation, manual tightening is minimised and repetitive handling is reduced, improving operator efficiency. The integrated clamping-force safeguard is designed to protect the tool retention under the vibration conditions found in high-frequency hammer-drilling, ensuring fewer stoppages and more predictable production cycles.

Compact B12 mount and bidirectional rotation for flexible machine use

A compact B12 mounting interface makes this chuck suitable for installations where space is limited but secure attachment is required. The capability for right- and left-hand rotation enables reversible drilling and tapping operations without changing the tool holder, expanding the range of tasks that can be completed with a single chuck. With an outer diameter of 42.8 mm, the unit occupies minimal spindle real estate while providing stable support for a wide range of drill sizes.

Wide clamping range and industrial application scope

The 1–13 mm clamping range accommodates everything from slender pilot drills to general-purpose twist drills, reducing the need for multiple chucks. Built for routine workshop use and tougher industrial environments, the chuck is suitable for handheld and stationary drilling where quick changes and dependable retention matter. Its construction and functional concept favour maintenance-friendly operation, helping to lower the risk of lost tools and the associated production interruptions.
