Without using a drill press or drill stand, you can drill perfectly perpendicular holes on any cylinder or sphere, flat surface or edge for a fraction of the cost of other portable alignment jigs. With the Drill Guide And Bushings you simply install a bushing into the plastic guide and your drill only has to bore perpendicular holes:

V-groove holds the guide steady on cylinders and spheres.

Automatically centers on a board's side so it's easy to drill dowel holes.

Includes 6 hardened steel bushings for 3/16", 1/4", 5/16", 3/8", 7/16" and 1/2" holes.

Centerpunch locator included.
