China PDC Hole opener bits manufacture



Feature of PDC Drill bits:

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 buildupand increasing penetration.

A range of PDC cutting structures are available for a variety of formation conditions.
The fixed-diameter hole openers are 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 openers 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.
