Reaming and countersinking are processes to optimise pre-machined holes. As a world-wide leading manufacturer of drilling tools, Guhring provides reaming and countersinking tools made naturally to the highest Guhring Quality.

With the new HR500 reamers for the highly accurate finish machining of through or blind holes, Guhring sets new standards for reaming operations. HR500 reamers enable cutting speeds, feed rates and surface qualities that so far could only be achieved with considerably more sensitive cermet reamers.
