Using the DeWalt DW1649 Self - Feed Bit Kit is easy. First, select the appropriate self - feed bit according to your drilling task. Attach the bit to your drill using the 7/16' ball groove shank for a quick and secure fit. If you need to reach deeper areas, you can use the 5 1/2 - inch extension. When drilling, make sure to apply steady pressure and let the aggressive spur do its job for fast penetration. Remember to wear safety goggles and other protective gear. For maintenance, after each use, clean the bits with a brush to remove debris. Check the bits regularly for wear and tear. If a bit gets dull, you can resharpen it thanks to the open tooth design. Keep the kit in the provided box to protect the bits and replacement parts from damage and keep them organized.
