Adjustable Expanding Shell Reamers Type H

The adjustable shell reamer.

Application:

The reamer for inline reaming of a series of holes, particularly the holes of bearing tunnels.

Description:

Right-hand cutting shell reamer with expanding blades.
Due to the unique Hunger relief grinding operation the blades have a progressively increasing clearance angle giving a soft cutting action.
The reamer fits on a tool bar and may be positioned along the tool bar at any desired position. The reamer is automatically locked in place on the tool bar by an expanding spring coupling as soon as the reamer blades are brought into engagement with the bore.
Expanding tool bar guides and supporting fixtures for the tool bar are available to ensure excact alignment of the tool bar when reaming a series of aligned holes.
The adjusting nut is marked with annular scale. One graduation of the scale corresponds to a change of the reamer diameter by 0,02 mm.
The reamers are fitted with blades made of high quality special steel to ensure superior cutting performance.

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.
