kwb 8-Piece Diamond Hole Saw Set Ø 4, 5, 6, 7, 8, 10 and 12 Mm with Diamond-Coated Cutting Surface, High Precision, Large Material Ejection, Round Shank Drilling Template in Sturdy Plastic Case

DIAMOND-SPREADED CUTTING SURFACE: The kwb hole saw for stone is sprinkled with high-quality industrial diamonds and is therefore also designed for use in particularly hard tiles, porcelain stoneware, tiles, ceramics, granite, natural stone and marble slabs. HIGH PRECISION: The solid material base body of the diamond centre drill hole saw is precisely turned and ensures high concentricity and precision when working. LARGE MATERIAL EJECT: Due to the large holes of the diamond drill bits for tiles, an optimal material ejection is possible and the drill cores can be removed more easily after drilling. WITH ROUND SHAFT: With the round shank, the hollow drill bit fits all rotary and impact drills and is ideal for dowel holes. WITH DRILLING JIG: The drilling jig has a suction cup and connections for a water guide for cooling, which is necessary when drilling with the diamond hole saws for tiles.
