WESSF Slip/Fixed Renewable Drill Bushings (Type SF)
103 Products
Wescon WESSF slip/fixed renewable drill bushings are Type SF bushings, the kind aircraft mechanics know as slip fit bushings for egg cup drill guides. The bushing slips into a press fit liner and is held by a lock screw or clamp, so a worn bushing or a size change takes seconds without disturbing the guide or the jig. They are made for high volume production drilling where bushings wear out before the job is done, and for drill then ream or tap sequences in the same hole.
Each bushing is hardened steel for wear resistance and holds tight tolerance on the drill. Sizes cover wire gauge, fractional and decimal drill diameters in 5/16, 1/2 and 3/4 in outside diameters, 1/2 to 1 in long. Use them with Wescon egg cup and tri-pod drill guides, slip/fixed renewable bushing guides and drill bars.

Cross Reference SearchWhat takes a WESSF slip fit bushing
Most slip bushings sold for aircraft work are 1/2 in OD and 3/4 in long. WESSF slip fit bushings come in that size and also in 5/16 and 3/4 in OD, 1/2 to 1 in long, all Type SF, so one bushing moves between the egg cup drill guides, the dog bone guide, the drill bars and the WES5831 handle. Pick the row for the bushing outside diameter and length, then the tool. A shorter bushing also fits the guide made for the longer one of the same OD. Drill bars take the 1/2 in long bushings only. The bore range is set by ANSI B94.33 and depends on the outside diameter, not the length.
