CENTROTEC screwdrivers

Bits and bit holders on the CENTROTEC shank, which drops straight into the tool chuck without a drill chuck in between — shorter, lighter, and with the tool running truer. Bits come in Phillips, Pozidriv and Torx in the sizes that actually turn up on site, in 50 and 100 mm lengths; the long ones reach into a recess a stubby bit can't. Bit holders extend reach and hold spare bits magnetically in the shaft, so the size you need next is on the tool rather than in a pocket. Adapters take 1/4" and 3/8" square drives for socket work.
