The universal reamer with dual-sided guidance.<\/p>

Application:<\/h3>

For boring and\/or reaming all types of holes, especially widely spaced aligned bores.Double centering and support ensure maximum precision.The boring cutters allow for a coarse pre-cut before the actual finishing cut.<\/p>

Design:<\/h3>

Right-hand cutting hand reamer, each equipped with a guide rod with a square drive and a conical centering sleeve on each side.Both guide rods are interchangeable and can be replaced with extended guide rods.Blades with a cylindrical pilot, boring edge, and subsequent reaming edge.Blades with the unique Hunger special grind (progressively increasing clearance angle) ensure a smooth, soft cut.Adjustment nut with setting scale, where one graduation mark corresponds to a change in the cutting diameter of 0.02 mm.The reamer blades are made of special steel characterized by particularly good edge retention.<\/p>

The production of reamers with hard-chrome plated blades as well as hard-chrome plated replacement blades has been discontinued. Remaining stock is still available and deliverable as long as supplies last.<\/i><\/b><\/p>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:\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
