At SML, we offer precision-engineered roller cone reamers designed for optimal performance in demanding drilling environments. Our reamers feature advanced hard alloy coatings that enhance wear resistance and extend tool life. Utilizing a robust welding process, each component is securely fixed to withstand the rigors of tough rock conditions. Equipped with durable cutting edges derived from single tooth palms and tooth wheels of tricone bits, our reamers are engineered to provide efficient borehole enlargement and reliable reaming. The reaming action is driven by the torque of the screw drilling tool and the tension of the drilling rig, ensuring consistent and effective operation.

Rock Reamer has the advantages of strong geological adaptability, high design strength, good wear resistance, long service life and good safety performance, which can further improve the efficiency and quality of PDC reamers and is suitable for long-distance directional crossing construction.
The primary difference is in the cutting mechanism. Roller Cone Reamers use rotating cones with teeth to cut through rock, while Fixed Cutter Reamers use stationary cutting elements. Roller Cone Reamers are generally preferred in more challenging geological formations due to their ability to handle uneven and hard rock conditions.
