Cylinder Head Drilling Guide Tool Set for Broken M8 and M10 Bolts, 28-Piece

This 28-piece drilling guide set is designed for accurately drilling out broken or damaged M8 and M10 studs and bolts.

It is particularly suitable for threaded connections on exhaust manifolds, intake manifolds, cylinder heads, gearboxes, differentials and similar components where the bolt size and spacing allow the guide to be mounted.

The adjustable three-arm drilling guide and its low-profile design improve access when drilling directly on the installed component. The guide bushes keep the drill bit centred and prevent it from wandering, reducing the risk of damage to expensive engine and drivetrain components.
