Boneham 30 x 25mm Headed Bush

Head metric drill bushing is the PH type of drill bushing meets European and UK standards. This headed drill bushing is similar to the PP type but features a head to allow greater axial force, so not to slip out the plate and aids where it is desired, to feed down to a dead stop. The head of the bushing also allows it to be pressed into the plate easier and can be left either exposed above the plate surface or counterbored to sit flush.
