Confirmat Screw Two-Piece Drill Bit 7x 50mm
The Confirmat Screw Step Drills from Snappy are designed so you can easily replace the brad point drill (sold separately) if it is damaged. Shanks are 1/4" hex so they can be changed for the PoziDrive driver bits in a snap. Use #2 PoziDrive with 5x40 Confirmat Screws and #3 with 7x50 Confirmat Screws.
