Pro-Tip

When drilling deep holes through multiple studs or thick headers, avoid the temptation to "push" the bit. The self-feeding Dura-Tip™ is designed to pull the bit through the material for you. Simply maintain a steady speed and let the bit do the work. To prevent stalling, occasionally pull the bit partially back while it is still spinning to help clear any packed sawdust from the extra-deep flutes, especially when working in green or pressure-treated lumber.
