Lenox 1787561 1-1/2 Bi‑Metal Self Feed Bit

Using this Lenox 1787561 bi-metal self-feed bit is a breeze. First, make sure your drill has a 1/2-inch quick-change adapter that can fit the bit's hex shank. Then, insert the bit into the adapter firmly. When you start drilling, place the aggressive lead screw tip on the spot you want to drill. The tip will pull the bit through the material quickly. For best results, keep a steady hand and apply moderate pressure. When drilling through nail-embedded wood, the high-speed steel cutting edge will handle it well, but don't push too hard. After drilling, the chamfered edge allows you to remove the bit easily. The flutes will have cleared most of the wood chips, but you can give the bit a quick tap to get rid of any remaining ones. As for maintenance, after each use, wipe the bit clean with a dry cloth. If it gets dull over time, you can use a sharpening tool designed for drill bits. Keep the extra lead screw and wrench in a safe place so you can use them when needed. Always store the bit in a dry place to prevent rusting.
