Characteristics of BLUE-LINE core drills:
HSS-XE special steel

•  Made of high-alloy HSS-XE special steel
•  Thus extreme hardness at the tooth tips (up to 68 HRC)
•  Long service life

Step hardened HSS core drill

•  Standard hardened HSS core drills in stages
•  As a result extremely hard tooth tips (68 HRC) and still flexible core drill

Completely sanded from the full material

•  This fine grinding increases the cutting performance while reducing friction
•  For more service life

unique and patented Durablue coating

•  Extreme surface hardness and smoothness
•  Extreme service life even under less than ideal working conditions such as overhead work, dry drilling, etc

Five cutting geometries

•  Specially adapted cutting geometries especially for the different diameters and cutting depths
