The valve guide reamer with an extra-long shank.

Application:

For reaming valve guides in internal combustion engines.

Design:

Right-hand cutting reamers with adjustable blades and extra-long cylindrical shank with square drive. Cutting edges with the unique Hunger special relief grind (progressively increasing clearance angle) ensure a smooth, chatter-free cut.
A pilot bushing available for each reamer size, which is pressed against the valve seat during reaming, facilitates handling and ensures maximum precision. (See brochure)
The reamer blades are made of high-grade tool steel, renowned for superior edge retention.

Production of reamers with hard-chrome plated blades as well as hard-chrome replacement blades has been discontinued. Remaining stock is 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 alloys and copper alloys (bronze and brass), as well as materials with a high abrasive effect that tend to stick and form built-up edges.Sizes:
