Rocker Stud Boss Cutter

For precision threaded 3/8” stud conversion. No need to pull the rocker arm studs before machining the pad. This Boss Cutter uses the stud as a pilot, allowing better line-up and providing consistent angularity between the stud and the cylinder head. Excellent results can be obtained with a hand drill or the use of a seat & guide machine. Built in depth stop screw. Hardened body for long life. Cutter comes with two replaceable carbide blades. Optional pilot available for use when existing rocker studs are bent or damaged. Also available is a piloted tap eliminating the need for an alignment fixture.
