Application The reamer for reaming longer holes and adjacent holes to be reamed in line with each other. Description Right-hand cutting reamer with extra-long expanding blades. The blades are approximately 2/3 longer than the blades of reamer type D. Due to the unique Hunger relief grinding operation the blades have a progressively increasing clearance angle giving a soft cutting action. The reamers are available with standard blades made of high quality special steel to ensure superior cutting performance. The reamers are also available with hard chromium coated blades. The hard chromium coating has superior hardness in combination with a low friction coefficient. Thus reamers of the "hard chromium" series are particularly suitable for reaming abrasive materials and materials with a tendency to adhere to and to build-up the cutting edge.

Application The versatile reamer for reaming longer holes and adjacent mating holes. Description Right-hand cutting reamer with expanding blades. Integral pilot with guide sleeves at the front end of the reamer. The guide sleeve provide for exact alignment between the hole being reamed and the other mating hole. Due to the unique Hunger relief grinding operation the blades have a progressively increasing clearance angle giving a soft cutting action. The adjusting nut is marked with a annular scale. One graduation of the scale corresponds to a change of the reaming diameter by 0,01 mm. The reamers are available with standard blades made of high quality special steel to ensure superior cutting performance. The reamers are also available with hard chromium coated blades. The hard chromium coating has superior hardness in combination with a low friction coefficient.

Application The universal reamer for all types of holes, particularly for in-line reaming of two or more holes and for reaming very long holes. Description Right-hand cutting reamer with expanding blades. Interchangeable pilots with guide sleeves at the front as well as at the back of the reamer. The guide sleeves provide for exact alignment between the hole being reamed and the other mating holes. A special bayonet coupling with mating cones between each pilot and the reamer body ensures correct alignment. Due to the unique Hunger relief grinding operation the blades have a progressively increasing clearance angle giving a soft cutting action. The adjusting nut is marked with a annular scale. One graduation of the scale corresponds to a change of the reaming diameter by 0,02 mm. The reamers are available with standard blades made of high quality special steel to ensure superior cutting performance. The reamers are also available with hard chromium coated blades.

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 available with standard blades made of high quality special steel to ensure superior cutting performance. The reamers are also available with hard chromium coated blades.

Right-hand cutting reamers with adjustable blades and with extra long cylindrical shank with square. Cutting edges with the unique Hunger special grinding (progressively increasing clearance angle) ensure a soft and smooth cut. A guide bush, which can be supplied in addition to each reamer size and which is pressed against the valve seat during reaming, facilitates handling and enables optimum accuracy. (see leaflet) The blades of the reamer are made of special steel, which is characterized by particularly good edge retention. In the "hard chrome" version, the blades are also hard chrome-plated. The hard chrome layer is characterized by high hardness and low coefficient of friction. Reamers of the "hard chrome" version are therefore particularly suitable for reaming materials with a high wear effect and materials that tend to stick and form built-up edges.

Right hand cutting solid reamers with extra long shanks. The front end of these reamers is ground to act as pilot. The cutting edges are precision ground with a gradually increasing relief angle to eliminate chattering and to permit easy and smooth chip formation. The reamers are provided with a hard chromium coating. The very hard chromium coating reduces friction, giving improved chip flow and reducing the tendency for built-up edges.
