DeWalt DWA1790IR 3-Piece Titanium Nitride Coating Impact Ready Step Drill Bit Set 1/8 - 7/8

Using your DeWalt 3 - Piece Step Drill Bit Set is easy. First, choose the right drill bit for your job according to the step sizes. For smaller holes, pick a bit with a smaller initial step. Insert the 1/4' hex shank into your impact driver or rotary drill. When drilling, start slowly and gradually increase the speed for a cleaner hole. The split - point tip helps start the hole quickly, so let it do its job. The laser - engraved numbers on the bit will show you the size of the hole you're making. When you're done, clean the bits with a dry cloth to remove any debris. Store them in a dry place to prevent rust. Remember, this set is optimized for impact drivers, but it also works great with rotary drills. If you notice the bits aren't cutting as well, it might be time to replace them. Always wear safety goggles when using these drill bits to protect your eyes from any flying debris.
