YES, the Woodchuck drill bit is heat-treated to withstand hitting nails and other hazards. It is recommended that the nail be removed from the wood before continuing the job. This is a safer practice and will extend the life of the Woodchuck drill bit. If you should hit a nail, the Woodchuck can be quickly resharpended for a fresh cutting edge. Always read safety instructions on Woodchuck packaging before using your Woodchuck drill bit.
Large heads (1-3/4" and larger) should only be run in low speed or low gear. Small heads (1-1/2" and smaller) may be run at high speed.
Yes.
The 1-3/16" drill bit head is the optimal size for electrician and plumbers. The 1-1/8" drill bit drills a hole that can be too tight around conduit to fit a 90 degree bend through multiple boards. The 1-1/4" drill bit leaves a hole that is too large for many builders and municipal codes. The 1-3/16" fits both applications. It drills a hole large enough to bend a 90 degree piece of conduit through multiple boards while mantaining proper hole size to satisfy the requirements of many building inspectors.
With the growing popularity of nine-foot ceilings and basements, the added length allows electricians easier accessibility to these hard to reach areas. The 24" shaft helps alleviate back pain when drilling through floors and hard-to-reach areas electricians and plumbers face.
The Woodchuck drill bit is made on state-of-the-art machinery. By machining rather than welding, we are able to produce custom sizes to satisfy a variety of applications.
