Customized steel tooth reamer

Product features

Exclusive customized solution: Based on the hole diameter requirements of the drilling project (50mm-1500mm), formation hardness and equipment model, the number of steel teeth, tooth profile Angle (sharp teeth/flat teeth are optional) and base size can be customized to precisely match personalized operation needs.

High-strength steel tooth configuration: Forged and cut teeth are made of high-quality alloy structural steel, and undergo carburizing and quenching treatment. The surface hardness reaches HRC55-60, with excellent impact resistance. They are not prone to chipping or breaking in fragmented strata.

Optimize the slag discharge structure: The spiral intertooth slag discharge groove design, combined with the inclined water spray holes, reduces the accumulation of rock chips on the surface of the reamer, increasing the slag discharge efficiency by 30% and avoiding energy waste caused by repeated cutting.

Flexible and adaptable design: Equipped with standardized connection interfaces, it can be quickly integrated with mainstream equipment such as horizontal directional drilling machines and tunnel machines, supporting operations at different speeds (50-300r/min) without the need for additional equipment modifications.

Core advantage

The Nemesis of hard strata: For hard rock strata such as granite and basalt, the steel teeth have a significant advantage in impact resistance. The reaming efficiency is 15%-25% higher than that of traditional PDC reamers, making it particularly suitable for operations in fractured rock strata.

Cost advantage: Compared with PDC material, the manufacturing cost of custom steel tooth reamers is reduced by 20% to 30%, and the steel teeth can be replaced separately after wear without the need for overall scrapping, saving more than 40% in later maintenance costs.

Strong operational stability: The integral cast base structure has a torsional strength of over 800MPa, making it less prone to deformation during high-torque operations. This reduces the deviation of holes caused by equipment shaking, and the construction accuracy is controlled within ±5mm.

Nanjing Wanshi Technology Endorsement: With over 10 years of experience in the research and development of steel-toothed drilling tools, each reamer has passed strict quality inspections such as torque testing and fatigue strength tests. We offer a one-year free warranty and lifetime technical support.

Application scenarios

Mine roadway construction: Expansion operations for the development roadways of metal and coal mines, rapidly increasing the excavation cross-section to meet the requirements of ventilation and transportation.

Advanced support for tunnel engineering: Before tunnel excavation, the advanced small conduit holes are expanded to provide space for the installation of the support structure.

Horizontal directional drilling in rock strata: It is used for pre-reaming operations in the laying of underground pipelines (oil and gas pipelines) passing through mountains and rocky areas.

Geological disaster control: Expansion of anti-slide pile holes in landslide and collapse control to enhance the interlocking strength between the pile body and the stratum.

Building pile foundation engineering: Pile foundation expansion operations are carried out in hard rock strata to increase the bearing area of the pile body and enhance the stability of the foundation.

Working environment

Stratum adaptability: Skilled in handling hard rock strata such as granite, basalt, and quartzite, as well as fractured and weathered rock strata. It can also operate stably in strata mixed with pebbles.

Environmental tolerance: It can operate continuously within a temperature range of -20 ℃ to 80℃, adapting to extreme climate regions such as high altitudes, severe cold, and high temperatures.

Medium compatibility: It can operate in dry holes and water holes (clear water/mud) environments. The anti-corrosion coating on the surface of the steel teeth can resist the erosion of acidic groundwater.

Operation depth range: It is suitable for drilling operations from medium and shallow holes (≤500 meters) to medium and deep holes (500-1000 meters), meeting the requirements of most rock stratum engineering.

Nanjing WANSHIHOO has always been committed to "customizing solutions to drilling challenges" as its core. The customized steel-tooth reamer, with its strong adaptability to hard rock and controllable cost, has become the preferred tool for rock stratum construction.
