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.
