Headed Liner Bush
This range of drill bushes is similar to the PP range, but for the head. The headed drill bush type contain a ‘top hat’ or ‘shoulder’ at the top of the bush to allow greater axial force, so not to slip out of the plate, and aids where it is desired, to feed down to a dead stop. The shoulder, or headed part of the bush can be with countersunk to a flush position or left proud. Headed liners are used with fixed & slip renewable bushes and our permanently pressed into a drill jig or fixture plate.
