China Roller Reamer Suppliers: Durable and Efficient Manufacturing from a Trusted Factory
Product Application
Three different types (T, F and B) of cutters are offered:
Type T: Milled, machined with hard faced sharp teeth for soft formations.
Type F: Milled, machined with hard faced flat teeth, for medium hard formations.
Type B: Equipped with pressed-in tungsten carbide buttons, for hard formations.
Our Roller Reamer has a unique design that enables it to marginally increase the wellbore diameter while still rotating concentrically. It ensures optimal tool placement in the bottomhole assembly, not only guaranteeing maximum tool efficiency but also ensuring there are no negative effects on the bending stresses or contact forces.
Features
Low-torque cutting structure: The tool will generate less than 5% of the reactive torque generated by the drill bit with which it is used.
One-piece construction: All Roller Reamers are manufactured from a single piece of steel containing material properties. This ensures a strong, robust design that is properly paired with the adjacent drillstring components.
Unique blade layout: Our Roller Reamers are designed to offer maximum protection to the cutting structure during drillout and increase the efficiency of the blades to agitate cuttings on the low side of the wellbore in high-angle directional applications.
Cost-effective: A real-time solution that delivers improved wellbore geometry and reduced trip time.

Frequently Asked Questions
What are the different types of cutters available for the Roller Reamer?
We offer three different types of cutters: Type T (milled with sharp teeth for soft formations), Type F (milled with flat teeth for medium hard formations), and Type B (equipped with tungsten carbide buttons for hard formations).
What kind of formations is the Type B cutter suitable for?
The Type B cutter is equipped with pressed-in tungsten carbide buttons and is specifically designed to handle hard formations effectively.
Does the Roller Reamer generate high torque during operation?
No, it features a low-torque cutting structure. The tool generates less than 5% of the reactive torque compared to the drill bit it is used with.
How does the tool affect the wellbore diameter?
Our Roller Reamer has a unique design that enables it to marginally increase the wellbore diameter while continuing to rotate concentrically, ensuring optimal tool placement.
What makes the construction of these Roller Reamers robust?
They feature a one-piece construction. All Roller Reamers are manufactured from a single piece of steel, ensuring a strong and robust design that pairs perfectly with adjacent drillstring components.
What is the advantage of the unique blade layout?
The unique blade layout offers maximum protection to the cutting structure during drillout. It also increases blade efficiency to agitate cuttings on the low side of the wellbore in high-angle directional applications.
