Lenox 1787564 2-1/8 Bi‑Metal Self Feed Bit

Using this Lenox 1787564 bi-metal self-feed bit is a breeze. First, make sure your drill is set to the appropriate speed. Then, insert the bit into the drill using the 1/2-Inch quick change adapter. When drilling, let the aggressive lead screw tip do the work - it'll pull the bit through the material quickly. You'll notice that the flutes remove excess wood chips as you drill, keeping the hole clean. After you're done, the chamfered edge makes it easy to remove the bit. As for maintenance, keep the bit clean after each use. You can use a brush to remove any remaining wood chips. Store it in a dry place to prevent rust. And don't forget, each package comes with an extra lead screw and a wrench, so you can easily replace the screw if needed. Just be careful when working with nail-embedded wood - while the high-speed steel cutting edge is very durable, hitting a large nail could still cause some wear over time.
