80mm Hole Saw Drill Bit, HSS Bi Metal Cutter Bit for Cutting Wood, Plastic, Drywall, Plywood, Thin Metal, Plasterboard, Iron, Aluminum and Pipe

Circle Hole Saws- The HSS hole saws are perfect cutting tools for installing recessed lights into ceiling, for punching a big hole at wall to fit a vent pipe or an extract fan, for drilling a hole on wood board or drywall for cable installation. Faster Accurate Cutting- The increased hardness of the carbide technology and optimized tooth geometry allow our hole saw to provide faster and accurate cutting than standard hole saws, the diameter errors of the cut hole are less than a millimeter. Sharp Clean Cutter- These hole saws adopt bi-metallic cutting teeth, which are layered with high speed steel. It increases their hardness and durability, and gives the hole saws excellent cutting ability to drill a clean hole on wood. Power Efficiency Tools- The slug holes around the saw are able to remove the wood chips while cutting, reduce friction heat, improve the efficiency. Due to the fact that less of total amount of material is actually cut, much less power is required, longer battery life of power tools is benefited. Wide Application： The metal hole saw cutter is suitable for cutting holes in wood, plaster, drywalls, plastic, metal, nail embedded wood, plywood, pipes, steel and so on. The wood drill hole cutter won't come loose and won't slip when drilling.
