Pro-Tip: When using this segmented blade for dry cutting, always allow the blade to "air cool" by pulling it out of the cut and letting it spin freely for 10-15 seconds every minute. This prevents the diamond bond from overheating, which keeps the segments sharp and ensures you get the full 2X life potential from the blade.
