The Stahlwille 18120002 Stubby Ratchet Bit Holder has an ergonomically designed, non-slip 2 component handle for optimum force transmission. The bit holder has a knurled spin section for faster screwdriving and has a heavy-duty ratchet mechanism with 48 teeth (7.5° working angle). The bit holder is suitable for 1/4in hex bits and allows easy bit change, thanks to its internal magnetic hex drive. The direction (clockwise or anticlockwise) can easily be changed by twisting the locking ring.
