Hole openers are used to enlarge the diameter of a pre-drilled hole. They are custom built to specification, and come in a wide variety of sizes. A hole opener is sometimes referred to as a reamer. Roller cone hole openers are specifically designed for horizontal, rock drilling applications. Extensive tool performance experience combined with the pooling of hole opener expertise from various industries (directional crossing, mining and oil field) has aided in designing and manufacturing a proven line of horizontal hole openers for the trenchless construction industry. Our approach to tool application analysis and tool set-up recommendations includes cutting structure selection, hydraulics and torque and drag analysis. This comprehensive approach enables us and the contractor to minimize the number of reaming passes and optimize hole opener performance.

Tricone Roller Bits All sizes and IADC codes of drill bits are available. Special requirements of different models can be customized. 1)Main features 1. Cutting Structure of this type sealed and non-sealed tci tricone bits: The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit. 2. Gauge Structure of this type tci tricone rock bits: Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life. 3. Bearing Structure of this type tci tricone rock bits: High precision roller bearing with two thrust faces. Ball lock the cone. Thrust faces hardface with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved. For more info: www.crossingbit.com Hebei Crossing Drill Bit Manufacture CO.,LTD

Drill Bits
Power Screw Bits
We have 2units of Samsung (SD20) brand bulldozers brought from the Korean military. It's in good condition because it was brought from the military.
We specializes in drill bits, drill pipe, Mud pump and stabilizers for water well, oil field, construction, geothermal, directional boring, and underground foundation work all over the world. Our purpose is to sell the best quality products at the lowest possible price. We are professional supplier of new and used(rebuilt) drill bits used for oil filed, water well. Including tricone bits,PDC bits and drill pipe. Various of model and dimension available. Good condition and reasonable price. Product Description: Steel teeth Bits 114-117, 127 Soft Formation Tooth Bits The 114-117 bits are used to drill low-compressive strength, soft formation. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear. On the softest bits type this hard facing completely covers the bit teeth. 127 Medium-Hard Formation Tooth Bits The 127 bits are used to drill high-compressive strength, medium hard formations. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear. Medium hard with high compressive strength and hard streak (hard shale ,sandstone , limestone, etc.) 437 Soft Formation TCI Tricone Bits The 437 TCI bits are used to drill low compressive strength, very soft formations. TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, result in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations. 517 Medium Formation TCI Tricone Bits The 517 features aggressive chisel tungsten carbide insert on the heel rows and inter rows. This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard for-mationes. The HSN rubber O-ring provides adequate sealing for bearing durability. 637 Hard Formation TCI Tricone Bits The 637 bits can be used to drill hard and abrasive forma-tions. Wear-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-durability and long life. 617 Medium-Hard Formation TCI Tricone Bits The 617 feature robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fest drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-rin provides adequate sealing for bearing durability. Plywood case or according to the conform order.
