GP SYSTEM (SINGAPORE) PTE LTD - ROHM [Product 1: Supra-SK Rapid Clamping Drill Chucks]

*Type 141*	SUPRA-SK *Rapid Clamping Drill Chucks* Quick-action keyless drill chuck for percussion drilling machines of all makes. Self-clamping. A safety device reduces the risk of accidents by preventing the chuck from opening of its own accord even when subjected to heavy vibration and high
impact frequencies. The chuck is sealed against swarf and dirt. When drilling from below (over the head) the swarf is ejected through two holes in the conical sleeve. The drill can be clamped by hand simply and quickly. Automatic re-tightening in proportion to cutting force means that the clamping force is preserved even with tough jobs. The chuck can be opened easily by hand.
