Horn System DR range of high productivity high precision insert based modular reamers, developed for rapid sizing of blind and through hole diameters from 11.9 mm to 100.6 mm.  The System DR has been developed for use with steels, castings, non-ferrous materials and plastics.

Depending on the application, different cutting element geometries are available.  For through-hole applications a left helical fluted cutter is recommended whilst blind hole applications are served by straight fluted cutters.  All are available in a wide range of carbide or cermet grades.

A comprehensive range of holders and system adaptors is available.  Holders for diameters from 11.9 mm to 35.6 mm are available in two different lengths for aspect ratios of 3-4 x and 6-8 x hole diameter. In the case of longer length holders the option of either steel or carbide shank material is available. 

All are equipped for through-tool coolant supply; holders for through hole applications have coolant nozzles immediately behind the cutting element whilst blind hole applications are served by a coolant jet passing through the nose of the cutter/holder assembly.

Diameters from 35.601 mm to 100.6 mm are catered for by a modular shank/insert holder system which offers integrated run-out adjustment capability to maximize accuracy.
