All American Products Co. - Drill Bushings


1. All American anti-galling process creates a super finish which increases the life of both the drill and the bushing.		5. Blended radius at drill entrance improves proper drill entry and alignment which prevents tool wear and breakage. Hardness: Bushings are heat treated to Rockwell C62-64.
2. Steel: All American bushings are manufactured from either C1144 Stress proof steel or other high carbon steels known for their long wear and stability. Special materials such as tungsten carbide, 52100 steel, 300 & 400 series stainless steel, plus A2, D2, D3, M2, and M4 tool steels and bronze are also available.	6. For quick and proper identification, all bushings are clearly stamped with SIZE and TRADEMARK.
3. All American bushings feature a two-directional undercut and are ground square to allow the bushings to fit flush on top of the jig.	7. Slip fixed renewable (SF) bushing heads are knurled which improves operator handling when installing and removing bushing from jigs or fixtures.
4. All American bushing feature an inside chamfer which improves chip control and reduces tool wear.	8. Chamfers on the O.D. exit end of All American bushings eliminate peening which permits easy entry and removal.
