SMART365 SM-25-820 Diamond hole 82 mm Technical data: Diameter: 82 mm Maximum drilling depth: 35 mm Holder: M14 – for angle grinders Maximum speed: 12,000 rpm Height of diamond embankment: 10 mm Application: Dry Product characteristics: SMART365 drill range ideal for precision and clean drilling in hard materials such as: ggres, ceramic tiles, natural stones. The abrasive surface is made of diamonds embedded by vacuum soldering. Suitable for dry work. Drills and openings can make holes up to 35mm deep Mounting on the M14 thread gives the ability to work directly on angle grinders with maximum speed of up to 12,000/min or rotary grinders. The 20-75mm diameter openings allow accurate drilling of holes under hydraulic connectors, drains, electric cans, flush-off lighting. Side holes in laces 20-75mm provide better cooling and facilitate removal of the material. It is recommended to make circular movements for better cooling and extend the life of drills. For extended service life drills are recommended: Use of angle grinders or grinders at a speed not exceeding 12,000 rpm Dry drilling Making circular movements for better cooling Every time to remove the piece before another drilling At other auctions we have drills with diameters: 6, 8, 10, 12, 20, 27, 35, 45, 55, 65 and a suction cup guide.
