Abstract
A powered vinyl groover includes a motor attached to a circular blade and a blade housing for covering the circular blade. The blade housing includes a duct to carry cuttings into a collection bag. Near an inlet hole of the duct is a fin, which may be a raised surface on any interior wall of the blade housing extending into the blade housing as close as possible to the blade. The fin causes airflow from the blade to be redirected towards the inlet hole of the duct so that more cuttings enter the duct and are carried by the duct through to an outlet hole to a collection bag mountable over the outlet hole of the duct. The fin may be integral with the blade housing or attached to it, and a fin may also be added to existing groovers.
