Spyder 1-Piece 4 1/4-in Bi-Metal Non-arbored Hole Saw

Cut holes in a snap even at an angle. Drop out the core at the touch of a button. Push the button again to change blade diameters. Spyder's bi-metal hole saws feature variable tooth pitch geometry and tough bi-metal steel, making them the durable choice for drilling holes in wood with nails, metals, and plastics. Use with Spyder's Rapid Core Eject arbor system to remove cores without prying (drill hole, press button, pull back the hole saw, and eject the core), cut at an angle, and enlarge existing holes using two adapters on one pilot bit. Using a drill motor with a support handle is recommended. Not for use in hammer mode.
