60MM ADAPTER WITH STOPWATCH 2 MAGNETS RT-BIT-ADAP/2M

The adapter ring and thread allow you to tighten screws to the set depth. A strong internal magnet holds the bit and screw properly when screwing. An additional magnet on the ring makes it easier to screw in screws in hard-to-reach places and prevents quick wear of the tip. The 1/4" (6.35 mm) chuck allows you to use most screwdrivers and drill drivers available on the market.
