REAMERS, COUNTERSINKS DE-BURRING TOOLS COMPLETE RANGE 2014

Perfect reaming in all diameters HR 500 high-performance reamers are the optimal tooling solution for all diameters from 2.97 to 76.00 mm. To apply the optimally designed HR 500 high-performance reamer a range of various HR 500 options is available. Solid carbide reamers up to diameter 20.00 mm Carbide and cermet-tipped reamers up to diameter 40.00 mm Carbide and cermet-tipped head reamers up to diameter 76.00 mm Solid carbide reamers for intermediate dimensions and stepped tools in HR 500 Active programme

Maximum performance for all materials Our comprehensive HR 500 range includes reamers for the machining of most materials. The perfect combination of special geometries, tool material and coatings provides optimal machining results for all reaming operations.

DE-BURRING TOOLS Hole entries and exits - quick, clean and fully automated de-burring entry cutting edges moving into the transverse hole de-burring exit Guhring provides a comprehensive standard range of de-burring tools for the finish machining of hole entry, hole exit and transverse hole exit – including the world’s first solid carbide tools for the machine de-burring of hole entry and exit. Instead of a time and cost-intensive manual operation, de-burring in a fully automated operating process reduces the machining time.
