Using these Klein Tools slotted power driver bits is a breeze. Just insert the 1/4" hex shank into your impact drill. They're made to handle the power of impact drills, so you can use them for various jobs. When using, make sure the bit is fully seated in the screw head to avoid slipping. For maintenance, keep them clean and dry. After use, wipe them down with a dry cloth. Store them in a dry place to prevent rusting. Since they're made of high - quality steel and heat - treated, they'll last a long time if you take good care of them.
