About the Press-Fit Drill Bushing with Head
BOLTON catalogues this item as press-fit drill bushing with head3, and it is supplied against the reference 96977A150. It is a headed press-fit drill jig bushing with a 3 mm inside diameter, a 6 mm outside diameter and an overall length of 5.5 mm. Drill bushings of this type sit inside a hole in a jig or fixture plate and guide the cutting tool, so that hole position and perpendicularity are set by the fixture rather than by the operator. The press-fit form is installed permanently: the bushing outside diameter is made slightly larger than the fixture hole and is pressed home with a manual or hydraulic press, giving an interference fit that keeps it in place through repeated cycles. The head is the functional difference from a headless bushing — it bears against the top face of the plate and stops the bushing being driven through under the axial load of high-pressure drilling.

Typical applications
A 3 mm bore bushing guides small drills, reamers and counterbores, so it is used on jigs producing pilot holes, fastener holes for M3 hardware, dowel and locating holes, and repeat hole patterns in sheet and plate. With only 5.5 mm of length it is suited to thin fixture plates where a longer bushing would stand proud, while the head keeps it seated. Because the fit is permanent, it belongs on production and repair fixtures that will run the same operation many times rather than on a one-off setup.
