Manufacturer of rock drill bits, rock drilling tools.
It is common practice to bulge the drive end of the bit steel to
increase the strength of the rock drill end to accommodate larger
diameters and shank adapters. Drill steel is available in a variety
of standard lengths to match the variety of drill feeds available.
Since the joint does not go into the hole, a drill diameter closer
to the steel diameter can be used. This improves flushing and
drilling accuracy.
Drill bits, collars, shank drill pipe and tunnel drill pipe. Stem
lengths 2440mm to 6435mm, (8'-21') R25, R28, R35 bit end threads

• The cross-sectional dimensions of the material are measured
through the plane
• Cross section is stiffer, heavier and transfers energy more
efficiently
• Reduced annulus in borehole for better flushing
• Small spaces combined with steel corners create turbulent flow in
the hole
• Keeps heavy cuttings moving, especially when drilling
horizontally
• Rigidity of the cross section makes it possible to use larger
threads
