ABSTRACT:
The invention contemplates the provision of a double-shelled dust-collecting hood for a high-speed rotary cutting tool. The outer shell seals itself to the workpiece while the inner shell stands clear of the workpiece. The outer shell is open-ended so that the flow of air induced by a suction port within the hood enters at the unsealed end of the outer shell and reverses direction as it turns into the inner shell.
