The valve guide reamer with an extra-long shank.

Application:

For reaming the valve guides of internal combustion engines.

Design:

Right-hand cutting reamers with adjustable blades and an extra-long cylindrical shank with a square drive. Blades featuring the unique Hunger special grind (progressively increasing clearance angle) ensure a smooth, soft cut.
A pilot bushing, available for every reamer size and pressed against the valve seat during reaming, facilitates handling and enables optimum accuracy (see brochure).
The reamer blades are made of special steel characterized by particularly good edge retention.

Production of reamers with hard-chrome plated blades and hard-chrome plated replacement blades has been discontinued. Remaining stock is still available while supplies last.

As a replacement for the “Hard Chrome” version, the “DLC” version is now available, in which the blades are coated with diamond-like carbon (DLC). The DLC coating is characterized by extreme hardness and smoothness. At the same time, the sharpness of the cutting edges is maintained because the DLC layer is extremely thin.
The DLC version is therefore ideally suited for reaming aluminum and copper alloys (bronze and brass), as well as materials with a high abrasive effect that tend to stick and form built-up edges.
