DeWalt DWA1789IR 7/8 - 1-1/8 2 Step Titanium Nitride Coating Impact Ready Step Drill Bit

Using the DeWalt DWA1789IR step drill bit is easy. First, choose the right drill - either an impact driver or a rotary drill as this bit works with both. Insert the 1/4' hex shank firmly into the drill chuck. When drilling, the split - point tip will start the hole quickly, and the titanium two - flute spiral design will help remove chips efficiently. The laser - engraved numbers on the bit make it easy to know which step you're using. For best results, apply steady pressure while drilling. As for maintenance, after each use, clean the bit with a dry cloth to remove any debris. Store it in a dry place to prevent rusting. This will keep your bit in good condition and ready for the next project.
