Rohm Supra-I 3-16mm Capacity J6 Mount Keyless Drill Chuck

For workshops that demand the absolute peak of performance and capacity, Bolts & Industrial Supplies proudly presents the Rohm Supra-I 3-16mm J6 Mount Keyless Drill Chuck. This is not just a standard chuck; it is a heavy industrial solution, engineered in Germany for maximum precision and durability on stationary pillar drills and large-scale drilling machines. When your projects require larger drill bits and unyielding grip, the Supra-I is the only choice.

Built from hardened and ground high-grade steel, this robust chuck is designed for a lifetime of service in the toughest Australian conditions. Its keyless mechanism is a masterclass in efficiency, allowing for rapid, single-handed bit changes. The core of its superior performance lies in the automatic self-tightening system. This feature dynamically increases the clamping force as the drilling torque increases, completely eliminating bit slippage and ensuring every hole is drilled with perfect accuracy and safety. The precise J6 taper mount guarantees a rigid, concentric connection to your machine’s spindle, making it the definitive chuck for heavy-duty metalwork and fabrication.
