HR 500 Reamers - Guhring

Special solution HR 500 GT carbide- or cermet-tipped
high-performance reamers - technology and advantages
HR 500 GT high-performance reamers
Standard range and dimensions
Also above 40 mm diameter Guhring‘s HR 500 technology is the first choice for high-performance reaming.
Numerous intelligent solutions ensure that even with these large diameters optimal quality is guaranteed:
HR 500 GT cermet-tipped high-performance reamers as semi standard
Diversity for perfect machining results
HR 500 GT tool heads are available as a semi-standard with short delivery for the diameter range > 40 to 75 mm.
The following material specific designs with the proven HR 500 cutting edge geometry are available:
• Carbide-tipped with nanoA-coating for stainless steels, GGG 60, special alloys and non-ferrous metals
• Carbide-tipped with nanoA Cast-coating for GG
• Cermet-tipped for steels and GGG 40/50
We also manufacture special tools to customer specification upon request.
Optimal cooling lubrication
Thanks to the new developed, patent pending positioning screw on the face of the HR 500 GT tool head the cooling lubricant
accurately reaches the cutting edges. A blocking of the coolant exits by chips during the machining process is impossible due
to the very flat construction of the positioning screw. It is possible to machine blind holes directly up to the base of the hole.
Product information
• right-hand cutting
• extremely unequal flute spacing
• straight-fluted
• straight shank ~ DIN 6535 HA
tolerance h6 with tang for the
overlength, slim hydraulic chuck,
as well as for normal
hydraulic or shrink fit chucks
The HR 500 GT cermet-tipped HPC
reamer operates at highest cutting
rates (see GuhringNavigator) and produces
extremely high-quality holes. In
addition, it provides very high process
reliability. The coolant supply ensures
an optimal chip evacuation and an
optimal cooling.
