The CorePlus Diamond Holesaw provides professional, fast, clean cutting on a wide range of materials, from hard porcelain tile and stone to cement board and fibreglass. Leading-edge vacuum brazing technology ensures the diamonds stay bonded for extremely long life. Minimal water cooling is required when cutting hard tile, stone and glass. Use fully dry on other materials. Fluid, snag-free cutting, no secondary finishing required. The ultra-thin kerf generates a low amount of torque for faster cutting and extended battery life. Use with an arbor on a cordless drill or with an adaptor nut on an angle grinder.
