Bosch Multi-Size Screwdriver Bit Set

The Bosch Multi-Size Screwdriver Bit Set is a 21-piece collection of Philips， slotted and square screwdriver bits. It includes six power bits that fit directly into a drill chuck. The remaining 15 insert bits slot into the supplied compact drive guide， which lets you change drill bits without re-chucking. With their magnetic shafts， the insert bits included in this Bosch multi-size screwdriver bit set stay firmly in place during use. The drive guide has an outer sleeve that slides over the screw head to prevent slipping. It’s compatible with all 3/8-inch and 1/2-inch drills and accepts any 1/4-inch hex insert bit. For portability， the Bosch 21-piece bit set comes with a handy storage pouch. This includes a sewn-in belt loop for easy carriage. Further loops inside the case keep the screwdriver bits in place.
