BONEHAM Serrated Press-Fit Drill Bushing (SP): 3/16 in Inside Dia., 1/2 in Outside Dia.

A BONEHAM serrated press-fit drill bushing guides drill bits in jigs and fixtures for precision hole placement in metalworking and machining. The serrated outer surface locks into the mounting hole to prevent rotation during drilling, ensuring repeatable accuracy in production environments.

The BONEHAM SP328.1875 is a fractional-inch standard-wall serrated press-fit drill bushing with a 3/16 in inside diameter, 1/2 in outside diameter, and 1/2 in overall length. Tolerances are +0.0001 in/+0.0004 in for one dimension and +0.0000 in/-0.0002 in for another.

To install a BONEHAM serrated press-fit drill bushing, press it into a reamed or drilled hole in the jig plate using an arbor press or hydraulic press. Ensure the hole diameter matches the bushing's outside diameter tolerance. The serrations grip the plate material, so no additional locking is needed.
