Drill Bit Adapters:
Adapts standard drill bits listed to 1/4" hex shank for fast bit changes. Just add your standard twist drill to the adapter for easy use. Each adapter will accept the fractional or number size listed. Each adapter has a spring loaded steel collet that flexes to grip drill bits of similar size, including numbered, fractional and metric. Bit can be changed out in seconds with a wrench. Each bit adapter has a standard 1/4" hex drive that snaps into our quick change chuck. Replace only the drill bit when dull.
