Even an experienced Carpenter, they cannot guarantee that every time you drill a perfect vertical holes, let alone a novice. Now there is a tool, not only to ensure the vertical drilling, can control the depth.
Bullseyebore electric drill to aid the use of projecting concentric circle to help you visually-assisted, each perfectly drilled a vertical hole.
Ensure the vertical drilling make perfect holes
The drill will aid in projecting three shapes on the Board, the most out of graphics will change with the change for the drill, and 2 graphics will remain concentric structures. Starbucks iPhone 5 Case

When you drill and wood at a 90-degree, projecting figures there will be three concentric circles, this time to drill vertical holes in a Board.
Know the drill depth to avoid wood drill
For vertical drilling process, with the increasing depth of the hole slowly, the outer concentric circles vary slowly become smaller. Change the diameter of the outer concentric circles, is to make the depth of the hole.
For chestnut, if initially, concentric circles the outermost 4 inches in diameter, after completion of drilling, is 3.5 inches in diameter, indicating the depth of the hole is 0.5 inches. This is in order to avoid drilling through wood and specially designed.
