A buffing wheel rake is used to clean up the edge of an Airway Buffing Wheel while it’s running on a lathe or an angle grinder. Rakes last a very long time and you can replace just the metal filler if required instead of the whole handle. The buffing wheel should be spinning at it’s normal speed and the rake should be held securely when held up to a stationary bench grinder or lathe. On a grinder, please exercise caution when raking. We recommend using your feet to hold the rake to the ground and holding the angle-grinder to the rake to remove compound and soften the edges.
