Drill Bushings

Drill bushings guide the drill bit through a drill guide or drill bar so the hole goes in straight and in the right place. Wescon makes two kinds. WESSF slip fit bushings, also called SF or slip/fixed renewable bushings, drop into the holder and are held by a lock screw. WES5501 3/8-16 and WES5502 1/2-13 threaded drill bushings screw in, with no lock screw. All are hardened steel in wire gauge, letter and decimal sizes, made in USA.

Wescon drill bushings at a glance

Three series. WESSF slip fit bushings drop into a liner and are held by a lock screw, so one bushing fits every SF holder. WES5501 and WES5502 threaded bushings screw into the holder, no lock screw, and the holder must match the thread. All are hardened steel, made in USA.
