Imperial Blades One Fit 4-IN-1 Features Drywall Blade, 1PC (IBOA800-1) combines 4-in-1 features for more versatility within one blade. The dagger blade allows for detailed cuts, especially tight circular cuts. Depth gauge increments reflect drywall thickness and are designed to monitor depth of cuts. The piercing tips on each end initiate the cuts for a clean start, as well as adding push/pull cut capabilities. The shaver notches remove excess drywall if ran up and down along the cut while powered on. This allows the user to clean up their cut or shave off the most minimal drywall. Popular projects include electrical outlet boxes, can lights, PVC and more. One Fit anchor fits majority of non-Starlock multi-tools: Milwaukee, Ridgid, Ryobi, Bosch, DeWalt, Dremel, Fein, Makita, Rockwell and more.
