Geological Exploration 6 5/8" Drill Bit Adapter
Drill Bit Adapter Features
Integral Steel Rod is used by a hand held drill machine in
Underground mining and for small hole drilling, equipped with small
power rock drills, like air leg rock drills, hand held rock drills,
etc. It can reduces the expense of impact energy, improves the
drilling speed and efficiency, also it can be used for drilling
bore hole diameter from 30mm to 41mm usually.

DESIGN
Roschen drill pipes are designed with long and smooth transition
from upset to tube body to reduce the stress concentrations due to
the transition from the upset ID to the drill pipe ID.
All drill pipe and tool joints are manufactured in our modern and
technologically advanced manufacturing facility at Roschen. Each
tool joint is forged, machined, processed, inspected and tested by
qualified operators to ensure the quality meets or exceed API
specifications and customer’s requirements.
FEATURES + OPTIONS:
In addition to the standard manufacturing processes where customer
required, Roschen is able to perform hardbanding, internal coating,
thread cold roll and make & break to the highest quality standard.
TOOL JOINT MAKE & BREAK
Factory make & break performed in controlled procedure ensure
product consistency. This help to save valuable rig time and cost
while reducing risk of mishandling incident and rig downtime.
SURFACE PROTECTION
Phosphate coating are applied to all threads and seal shoulders of
connections to improve anti galling and corrosion.
Roschen can supply internal plastic coating according to customer
requirements. The coating forms a protective layer in the pipe ID
to prevent corrosion and thus extend the life span of the pipe in
the drilling environment.
ENHANCED FATIGUE RESISTANCE
Cold rolling of thread roots has demonstrated the beneficial
effects to improve fatigue resistance of the connections by
minimizing crack initiation.
HIGH PERFORMANCE ROTARY SHOULDER CONNECTION
Roschen offers its RS-DS and RS-MT series double shoulder
connections which outperform conventional API connections to meet
the needs of deep, extended and challenging wells with greater
torsional capacities.
