Special solution HR 500 G carbide- or cermet-tipped high-
performance reamers - technology and advantages

On the strength of the excellent results that solid carbide
high-performance reamers HR 500 achieve in the diameter
range up to 20 mm, Guhring has carried over this successful
concept to the new HR 500 G high-performance reamers for
diameters above 20.00 mm. HR 500 G brazed carbide- or
cermet-tipped high-performance reamers offer particularly
economical advantages for these large diameters in
comparison with solid carbide high-performance reamers
with comparable performance figures. In comparison with
conventional interchangeable head systems the brazed HR
500 G high-performance reamers are convincing thanks to
the following advantages:

•	considerably higher rigidity thanks to monoblock-design.    Carbide-tipped HR 500 GSTiAlN-coated high-performance reamers for the
•	additional errors in concentricity through additional       machining of blind holes, Guhring no. 1680

 interface are avoided.                                                        pfoarteglnotrtnhogeoaipvtsepuhsldaieiinnndkal
•	no restriction of coolant delivery by avoiding an

 additional interface
•	installation errors are impossible.
•	very simple handling.
•	higher rigidity against torsional and radial forces.
•	reduced tendency to chattering.
•	long tool life thanks to single interface installation

In order to offer the optimal tool material tip for every     Carbide-tipped HR 500 GDTiAlN-coated high-performance reamers for the
application range, tipped HR 500 G high-performance           machining of through holes, Guhring no. 1681
reamers are available with carbide inserts and TiAlN-
coating for the machining of cast iron and special steels
or with cermet inserts for the machining of steels and
GGG materials. Detailed information regarding optimal
application can be found in the GuhringNavigator for these
tools.

The geometry of tipped HR 500 high-performance reamers
corresponds to those in solid carbide. Therefore, there is a
choice of four different tipped designs:
•	cermet or carbide-tipped HR 500 GS for the machining of

 blind holes.
•	cermet or carbide-tipped HR 500 GD for the machining of

 through holes.
