Introducing the New XR32 Thread Design for Drifting and Tunneling Operations
Rockmore International has announced a revolutionary new thread design, XR32, to improve
precision and efficiency in drifting and tunneling operations, and to extend thread life.
This new thread design is the product of Rockmore's in-house R & D and manufacturing
facility, in response to demand from underground drillers for a stronger and more powerful
drill string. Extensive lab and field testing has demonstrated the effectiveness of the
|
XR32 thread system in providing more efficient energy
transfer, higher bit penetration rates, and longer thread life for both bit and rod. The new
XR32 thread is employed at the bit connection end for hex drifting and tunneling rods, and
is used for both male and female components - both tunneling bit and rod. The other end of
the rod, connected to the coupling or shank adapter has a standard thread such as R38 or T38.
That means smooth integration into your existing drill string.

MultiPoint - The Next Generation of Carbide Inserts for Button Bits
Rockmore International, a global manufacturer of rock drilling tools, has developed a
revolutionary new carbide insert design for their button bits, the MultiPoint.
In percussion drilling, penetration rates depend on efficient crack propagation. With a
conventional hemispherical insert,
|
there is a single tangent point striking the rock, resulting in
the rapid development of wear flats. Rockmore's exclusive new carbide insert design
provides multiple strike points for more efficient rock fracture and longer insert life.
Extensive rock-drilling trials showed that Rockmore's button bits with MultiPoint
inserts last up to 20% longer than the standard hemispherical design, and increased
penetration rates by 10%. Wear flats appeared slower and later in the insert life
than with hemispherical inserts. Testing also revealed that the MultiPoint inserts
provided smoother bit rotation and advancement.
