Wescon WES5800 Adjustable Drill Bar, SF Bushing - 1/2 in Bushing

A drill bar, also called a snatch block or steam boat, lines a drill bushing up over an existing hole so the drill or reamer cannot wander. The Wescon WES5800 is the single ended version for 1/2 inch or 3/4 inch OD SF slip/fixed renewable bushings, the same bushings used in egg cup drill guides. Clamp the bar through its slot with clecos or bolts, set the bushing over the hole, lock it and drill. Use it to repair a mismatched or crooked hole, ream to the next fastener size, or pull a slightly offset hole back to position on aircraft sheet metal. Anodized aluminum, half a pound, made in USA. Order it for 1/2 inch or 3/4 inch bushings, or see the WES5801 for both in one bar.
