Kata 20pcs Hole Saw Kit Hole Saw Set with 34-6,Maxsize 6 inch Hole Drill Bit,Ideal For Soft Wood,Plywood,Drywall,Pvc C

KATA hole saws are used to cut perfectly round holes in a wide variety of materials. Because they only cut out the perimeter line of the hole, they are much more efficient than a spade drill or twist drill. Besides they can be used in conjunction with corded drills, cordless drills (of 18 volts or higher), drill presses, and even lathes, provided they have a 3/8 or 1/2 inch chuck.
