S Type Imperial Jig Bush BS1098 Pt.1 1967

S Type Imperial Jig Bush BS1098 Pt.1 1967. Imperial Headed Drill Bushes or Headed Jig Bushes are dimensionally the same as the imperial plain bushes but feature a head. The head of the drill bush can be counter bored into jig if a flush finish is still required. The benefit of using a headed bush is that they can cope with great axial forces. Drill bushes can also be used for the accurate alignment of workpieces or composite mouldings.
