PDC hole opener is a reliable solution for hole enlarging in both
soft and medium. The body is machined
of a single block of AISI 4145H alloy steel. The unique design of
the body ensures maximum strength
and durability. It can withstand loads far beyond those involved
during normal drilling operations.
The PDC hole opener is designed for use in soft clays and shales to
medium-hard shales and limestones
and is particularly effective in sticky formations where balling
problems are encountered. Jets with
replaceable nozzles continuously clean the tool’s cutting
structure, clearing debris buildup and increasing
penetration.
A range of PDC cutting structures are available for a variety of
formation conditions. The fixed-diameter
hole opener is available in sizes 6 1/4 to 42 in. Tools for hole
several sizes are designed with special blades.
The robust design and construction enable drilling of longer
intervals.
In HDD(horizontal directional drilling ),the PDC hole opener can
enlarge the hole safety and efficiency,its
superior structure can made the hole smooth and more stability,its
unique JFA design made the cuttings
evacuation more quickly, it can rotary with less torque and
penetrate with less stress. Customs can choose
suitable grade of PDC cutters for different formations.
