Adjustable valve guide reamers type V
The valve guide reamer with extra long shank.
Application:
For reaming the valve guide of combustion engines.
Description:
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.
