Application:

The Hunger RDS is designed to precision machine the seat ring bores in cylinder heads to produce smooth and closely fitting contact surfaces for oversize seat inserts.

Features:

The RDS is equipped for counterboring as well as for facing the bottom of seat ring bores in a lathe-type action with a single point carbide cutter. The RDS is aligned in centerline with the valve guide by means of a pilot which is locked in the valve guide. An universal steady stabilizes the RDS against lateral displacement.
Pilots and steady furnished with Hunger valve seat refacing tool also suit for the corresponding RDS tool.
The built in feed gear mechanism for automatic longitudinal and cross feed of the single point cutter eliminates the need for multiple cutter sets and other accessories.
An adjustable stop for the tool slide permits quick selection of the proper sized bore diameter.
