Lenox 30881-VB1 #1 varibit

Using the Lenox 30881 - VB1 #1 Variable Bit is easy. Just chuck it into your drill with a 1/4 - inch chuck size. When you start drilling, the split - point design will quickly penetrate the material with less movement. It can cut holes in various sizes from 1/8 to 1/2 inches. For best results, make sure your drill is running at an appropriate speed. When you're done using the bit, clean it with a brush to remove any chips. Store it in a dry place to maintain the steam oxide coating and extend its life. Avoid using it on extremely hard materials that could damage the bit.
