All American Drill Bushing Benefits
The anti-galling process creates a super finish which increases the life of both the drill and the bushing. Our drill bushings are manufactured from either C1144 Stressproof steel or other high carbon steels known for their long wear and stability.
All American bushings feature a two-directional undercut and are ground square to allow the bushing to fit flush on top of the jig. They also feature an inside chamfer which improves chip control and reduces tool wear.
Blended radius at drill entrance improves proper drill entry and alignment which prevents tool wear and breakage. For quick and proper identification, all bushings are clearly stamped with size and trademark. Chamfers on the O.D. exit end of All American bushings eliminate peening which permits easy entry and removal.
