The Hole Pro® twin-blade X models can cut a variety of materials including wood, plywood, sheetrock, plaster, MDF, fiberglass, and up to 20-gauge brass and aluminum sheeting. The minimum diameter for all the X models is 1-7/8″, and the maximum diameter, for the Model X-425, is 17″. All twin-blade kits come in a heavy-duty carrying case and include a clear Tri-Slot Shield, as shown above, to catch shavings (the shield can also be used as a portable drill press), a pilot hole bit, two hex wrenches, and one set each of tungsten carbide blades and high-speed steel blades. The twin blades provide easy balance, are “infinitely” adjustable over the range of diameters, and will cut through 1″ material (if cutting from one side only; 2″ material when cut from both sides).
The Hole Pro® X-305, with a maximum capacity of 12″, costs $149.95. The X-148, with a maximum capacity of 5-7/8″, costs $119.95.
