We have been manufacturing adjustable hand reamers for over 100 years.
We are happy to advise you on using our reamers for specialized machining challenges.

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

As a replacement for the “Hard Chrome” version, the “DLC” version is now available, featuring blades 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 preserved 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 highly abrasive materials prone to galling and built-up edge formation.
