Diamond hole cutter for the drilling of porcelain ceramic tiles and most other materials. Best used with an angle grinder but can also be used on drills with the adapter attachment (PTTADP). M14 thread for direct attachment to angle grinders with an optimal operating speed between 10000 - 14000rpm. Top Tip: Apply light pressure when cutting and let the diamonds do the cutting. Use a swivelling motion at an angle dont hold it in one position. If you think the tool is getting too hot dip in a cup of water or stop and wait for it to cool down. Please Note:Do not hold straight and push hard on the tool. This will wear out the product very quickly. This also applies to all types of diamond tools.
