The new WORX® SD SemiAutomatic Driver has a six-slot revolving cartridge chamber that rotates screwdriver bits in and out without the need to touch the bit. You draw back the "magazine" (the cover) to advance a bit into the chamber, then slide it forward. All six of the bits you've loaded are stored within the cartridge. The WORX SD accepts 1" hex-shanked bits in slotted, Phillips, square-recess, hex or Torx configurations, or any combination thereof. The 1-pound tool has a 1/4" chuck and a no-load speed of 230 rpm with maximum torque of 27 inch/pounds. Included in the kit are the SemiAutomatic Driver, two bit cartridges, 11 screwdriving kits, a screw started drill bit for pilot holes and a 5-hour charger. The WORX SD SemiAutomatic Driver is priced at $49.99.
