CoroChuck™ 930 offers the best pull out security on the market due to the latest fulcrum technology used for upper most clamping performance with high clamping force. The secret behind the high precision and pull out security of CoroChuck™ 930 is the clamping mechanism, designed with fulcrum technology. A thin, brazed membrane with optimized clamping design expands to create two distinct clamping points on each side. This results in a consistently repeated clamping force, providing the best possible pull out resistance and damping performance. This design ensures excellent torque transmission to improve the performance of solid carbide end mills, drills and reaming tools. Performance is repeated over multiple clamping cycles to retain high quality component surfaces and extend tool life.
