Using these finger bits is easy. First, make sure your CNC machine is properly set up and turned off. Install the 1/2” gas male finger bit onto the machine. Select the appropriate stone material such as engineered stone, granite, marble, or quartzite. When starting the machine, set the feed rate between 250 - 300mm/min. During operation, keep an eye on the bit to ensure smooth cutting. After use, turn off the machine and carefully remove the bit. To maintain the bits, clean them with a soft brush to remove any stone dust. Store them in a dry place to prevent rust and damage. Avoid using the bits on materials that are too hard or abrasive other than the recommended ones, as this may cause premature wear.
