12 1/4'' PDC Hole Opener

Features

• Durable Steel Construction: Made from heat-treated AISI 4145H alloy steel.

• Efficient Load Distribution: Reduces risks by transferring load directly to the body.

• Optimal Cleaning: Nozzles are strategically placed to ensure proper fluid cleaning.

• Versatile Sizes: Available in sizes from 6 1/2 inches to 78 inches, accommodating various drilling needs.

• Wide Application Range: Ideal for both vertical and horizontal directional drilling.

Advantages

• Long-lasting Durability: Withstands heavy loads beyond normal drilling conditions.

• Reduced Risk of Failure: No axial load on pins reduces part loss downhole.

• Increased Efficiency: Optimized cleaning for faster and smoother drilling.

• Versatile Applications: Can handle a wide range of drilling operations, including HDD.

Funcation of hole opener

The hole opener is generally used after the pilot bit has drilled the original hole. A hole opener consists of a body with roller cones or it could be a fixed blade that would be dressed with PDC or crushed Carbide.

FAQs

Q1: What is a hole opener used for?
A hole opener is used to enlarge the wellbore beyond the original size drilled by the pilot bit. It helps in expanding the hole diameter for further drilling operations.

Q2: What materials are used to make the 12 1/4'' PDC Hole Opener?
It is made from high-quality AISI 4145H alloy steel, ensuring durability and strength for demanding drilling conditions.

Q3: Can this hole opener be used for both vertical and horizontal drilling?
Yes, the 12 1/4'' PDC Hole Opener is suitable for both vertical drilling and horizontal directional drilling (HDD).

Q4: How is the hole opener operated?
The hole opener is typically used after the pilot bit has drilled the initial hole. It consists of a body with roller cones or fixed blades, designed to be dressed with PDC or crushed carbide.

Q5: What are the benefits of using this hole opener?
It offers enhanced load distribution, reducing part loss downhole, and its nozzle design ensures effective fluid cleaning, improving drilling efficiency.
