Micro-Mark - 81852 Mini Drill Chuck for Cordless Screwdriver

Special Chuck Fits Cordless Screwdrivers for Slow Speed Drilling. Also works as an adapter for your oversized drill chuck, quickly converting it for precise drilling with micro size bits. Most drills and rotary tools spin too fast for working in plastic and for tiny detail work. Special chuck has 1/4 inch hex shank that fits your slow turning cordless screwdrivers and cordless drills to solve this problem. Take advantage of the quick-change feature of the 1/4 inch shank...buy several chucks and keep your most-used drill bits ready to go. Holds drill bits from 1/8 inch to #59.
