Size Range: 47-51 mmTakes Tool Bar: 25 mmLength Overall: 108 mmLength Blades: 48 mmNut Wrench Size: 43Number of Blades: 6Weight: 0,76 kgApplication:The reamer for inline reaming of a series of holes, particularly the holes of bearing tunnels.Design:Right-hand cutting shell reamer with expanding blades. 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 a circular scale. One graduation of the scale corresponds to an alteration of the reamer diameter by 0,02 mm.Order Information:The reamers are available with standard blades made from high quality special steel to ensure superior cutting efficiency. 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.
