Designed for horizontal directional drilling (HDD) contractors operating in complex geologies, the BR1/BR2/BR3 hard alloy rock core reaming blades combine extreme wear resistance with intelligent geometry to maximize reaming efficiency in mixed ground — from soft clay and sand to abrasive gravel, fractured shale, and medium-hard rock.
Manufactured by Zhuzhou Site Cemented Carbide Co., Ltd. — a Hunan-based specialist in high-performance tungsten carbide tools — each blade undergoes rigorous material verification, precision brazing, and post-process hardness testing. The result is a field-proven reaming solution trusted by HDD crews across Asia, Africa, and Latin America for its consistency, durability, and fast cycle times.
100% virgin tungsten carbide tips with coarse-grain microstructure resist abrasion 3.2× longer than standard grades — validated under real-world mixed-ground reaming cycles.
Shark Bite™ cutting edges and dual-angle Rock Reamer geometry deliver balanced penetration and chip evacuation across layered soils — reducing torque spikes and bore deviation.
OEM/ODM-ready: custom diameters (Ø80–Ø450 mm), mounting interfaces (weld-on, bolt-on, quick-change), and geometry tuning per geological survey data or project specs.

Provide your bore log or geological survey — we’ll recommend optimal BR series, tip geometry, and carbide grade for your specific formation.
Full engineering support for integration into existing reamer bodies: CAD drawings, tolerance analysis, weld procedure specification (WPS), and prototype validation.
On-site troubleshooting, reaming optimization workshops, and rapid replacement for wear-related failures under quality guarantee.
Standard MOQ is 50 pcs per model. For custom geometries or OEM integration, MOQ starts at 20 pcs — subject to engineering review.
Yes. Our HDD application engineers provide free pre-bore consultation — including formation analysis, reamer configuration recommendations, and performance benchmarking against comparable tools.
Each blade is individually wrapped in VCI paper, secured in a plastic box, then packed into a laminated wooden crate (36 × 16 × 10 cm, gross weight ~36.0 kg). Custom packaging (e.g., palletized, vacuum-sealed) available upon request.
