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.
The production of reamers with hard chromium coated blades and of hard chromium coated replacement blades has been discontinued. Remainders of stock are available as long as stock last.
The "hard chrome" version is replaced by the advanced "DLC" version, in which the blades are coated with Diamond Like Carbon (DLC). The DLC coating is characterized by extreme hardness, wear resistance and smoothness (very lowfriction). At the same time, the sharpness of the cutting edges is preserved because the DLC coating is extremely thin.
The DLC version is therefore ideal for reaming aluminum alloys, copper alloys (bronze and brass) as well as materials with a high wear effect and materials that tend to stick and form built-up edges.
