Q: How do I use a bit set like this?
Slide the bit you need into the included magnetic bit holder, or any standard bit holder or driver, since every bit has a standard 1/4" hex shank.
99W8665 - 99-Piece Not-So-Common Bit Set
Nothing puts the brakes on a job faster than not having the correct driver bit; this set ensures that’s unlikely to happen again. With a wide array of specialty driver bits in a range of sizes, it includes Imperial and metric hex, clutch, spline, Phillips, slot, Torx, Pozidriv, square recess, twin hole, 3Y and various tamper-proof bits.
Made from S2 steel hardened to Rc58-62, each bit is 1" long with a 1/4" hex shank to fit standard bit holders. The bits are marked for identification, and come in a fitted plastic case that holds them securely (so you won't have a jumble of bits to pick up off the floor if you accidentally knock the case over!). While a 2 1/4" long magnetic stainless-steel bit holder is supplied, the case also has an empty slot to hold your preferred bit holder. Included bits are listed below.
A must-have set for serious fix-it types, it's a whole case full of "just in case." An excellent buy.
