Rotec Diamond Dry Drill Premium 6x68 mm

The premium version has a thinner wall thickness, thus cuts faster and has a longer tool life. Vacuum-brazed diamond for high speeds and longer tool life. The drill bits are filled with paraffin, which provides cooling and abrasive retention. With 1/4" E6.3 attachment for use in all common (cordless) machines. To be used at the highest possible speed min. 1,500 rpm. Regular cooling breaks, possibly with water, increase the service life of the product. For drilling holes in hard fired tiles, natural stone, ceramic tiles and thin granite.
