Riverside Tool says you can turn an existing tool holder into a dust extraction tool by simply changing the nut. The AirPRO removes dust from nested cutting operations so it never has a chance to accumulate. Sawdust is ventilated directly into the CNC dust collection hood by the AirPro, leaving a cleaner cut and clean air behind, the company adds, helping woodworkers to extend tool life, reduce comdust, and save on labor.
