Application The VD2 is designed to reface valve seats of the engines of trucks. heavy construction vehicles and small ships. Features The VD2 refaces the valve seat in a lathe-type facing action. The tool head includes two inclined slideways for refacing 30° and 45° valve seats. A single point turning tool is clamped to tool slide guided in the respective slideway. When the VD2 is rotated around the pilot by hand, the turning tool travels in a circle around the valve seat with continuous outward transverse feed motion under the correct seat angle. A steady rest which is mounted on the cylinder head stabilizes the VD2 below the crank handle. The steady rest eliminates runout when rotating the VD2 around the pilot. As a result, the seat is refaced to concentricity with the valve guide under the correct seat angle.

Right-hand cutting reamers with adjustable blades and with extra long cylindrical shank with square. Cutting edges with the unique Hunger special grinding (progressively increasing clearance angle) ensure a soft and smooth cut. A guide bush, which can be supplied in addition to each reamer size and which is pressed against the valve seat during reaming, facilitates handling and enables optimum accuracy. (see leaflet) The blades of the reamer are made of special steel, which is characterized by particularly good edge retention. In the "hard chrome" version, the blades are also hard chrome-plated. The hard chrome layer is characterized by high hardness and low coefficient of friction. Reamers of the "hard chrome" version are therefore particularly suitable for reaming materials with a high wear effect and materials that tend to stick and form built-up edges.
