Using the DeWalt DW5225 drill bit is easy. First, make sure your drill is turned off and insert the bit into the chuck. If your bit has three flats on the shank, it will fit securely to prevent slipping, but remember the exceptions. When drilling, start at a slow speed and gradually increase as needed. This helps the bit make a proper start and reduces the risk of breaking. As you drill, the four - flute design will push out debris, so don't worry about clogging. For maintenance, after each use, wipe the bit clean with a dry cloth to remove any debris. Store it in a dry place to prevent rust. If you notice the bit is getting dull or damaged, it's time to replace it to keep your drilling efficient.
