Set a precise screw depth everytime using the Kobalt Drywall Bit Holder/Extractor along with your own impact gun. Created for pro customers and DIYers, this attachment has a single-handed operation for ultimate safety. Our patented cam assembly holds the fastener in place until it's embedded into a stud. Because there is no magnet, this is a debris-free bit. No more clogging up your tool with metal shavings. The built-in notch allows you to easily pull missed screws from drywall, instead of using your bare hands. Use with sheeting and framing material (drywall, fiberglass board, plywood, cement board, etc) around the house or the jobsite.
