Wood Boring Spade Bits

Wood Boring Spade Bits

Wood spade bits Spade bits are used for rough boring in wood. They tend to cause splintering when they emerge from the work piece. Woodworkers avoid splintering by finishing the hole from the opposite side of the work. Spade bits are flat, with a centering point and two cutters. The cutters are often equipped with spurs in an attempt to ensure a cleaner hole. With their small shank diameters relative to their boring diameters, spade bit shanks often have flats forged or ground into them to prevent slipping in drill chucks. Some bits are equipped with long shanks and have a small hole drilled through the flat part, allowing them to be used much like a bell-hanger bit. Intended for high speed use, they are used with electric hand drills. Spade bits are also sometimes referred to as "paddle bits."-From Wikipedia Our Magna Ultra Bore Spade bits feature: ■ Unique 15° Chisel EdgeTM design with more angle to dig into wood. ■ Iso-Temp® proprietary toughening process provides greater durability. ■ Angled Spurs cut a cleaner, smoother hole with less binding, blasting through wood knots that standard bits just can’t handle!
