Using the DeWalt DWA1786IR step drill bit is a breeze. First, choose the right drill, either an impact driver or a rotary drill. Insert the 1/4' hex shank of the drill bit firmly into the drill chuck. When starting to drill, let the split - point tip do its job. It will start drilling quickly as soon as it makes contact with the material. As you drill, the double - spiral flute design with titanium nitride coating will efficiently remove chips, preventing clogging. Make sure to use the laser - engraved numbers to select the correct drill bit size. When you're done using the drill bit, clean it with a dry cloth to remove any debris. Store it in a dry place to avoid rusting. Don't use excessive force while drilling as it may damage the drill bit. And always wear safety goggles to protect your eyes from flying chips.
