Review on Evolution Heavy Industrial Magnetic Drill by Bobby Posner

Great base magnet. Almost 700 holes have been drilled with the cheaper no-name ring drill set. This invention is 1000 times more efficient and productive. Good price. Excellent quality. Want a reversible spring on the drill handle because after drilling you have to move the drill and the drill gets all the way down in the drill making it difficult to move as you have to hold both the drill handle and the drill at the same time. . If you don't do this, the racquet will hit the material before anything else - bad for the racquet or the material.
