Bosch Daredevil® Wood Hole Saws are specially engineered to be 5X faster than standard wood hole saws, using Bosch's exclusive Turbo-Teeth design. This exclusive two-tooth pattern delivers faster drilling and longer life. These hole saws provide best-in-class results in wood and plywood applications. They have large chip clearance slots for easy plug removal, and their deep cup design was made to be the ideal choice for 2 x 4s. The Daredevil® Wood Hole Saws have an integrated arbor and pilot bit for use right out of the package.
