Greenlee LDTAP1/4-20 1/4-20NC Long Drill/Tap Bit

Using the Greenlee LDTAP1/4 - 20 drill and tap bit is a breeze. First, make sure your workpiece is made of mild steel, copper, brass, or aluminum and is no thicker than 1/2' (12.7 mm). Insert the 1/4' Quick - Change hex shank securely into your drill. You can perform drilling, tapping, and countersinking all with this single bit. Remember to use Greenlee cutting oil as it helps to get the best results and also prolongs the life of the bit. When using, the split - tip design will start drilling fast and stay in place well. After you're done, clean the bit with a dry cloth. Store it in a dry place to prevent rust. If you notice any signs of wear or damage, it might be time to replace the bit for safety and efficiency.
