Key Features
Applications Horizontal Directional Drilling, foundation drilling, trenchless pipeline construction.
Precision-engineered for HDD drilling in soil, sand, and soft rock — combining ballistic geometry with ultra-hard tungsten carbide for unmatched penetration and wear resistance.
BR1 is a high-performance welded hard alloy tooth designed specifically for horizontal directional drilling (HDD) tooling systems. Its patented conical bullet-shaped geometry delivers superior self-centering action and reduced torque resistance during entry into unconsolidated formations — while the fully sintered 100% virgin tungsten carbide tip (YK05/YG8C grade) ensures exceptional abrasion resistance against silica-rich soils, alluvial sands, and weathered sedimentary rock.
Manufactured by Zhuzhou Site Cemented Carbide Co., Ltd. — a Tier-1 supplier to global HDD equipment OEMs — BR1 teeth undergo strict dimensional validation, hardness testing (≥1480 HV), and thermal shock screening to guarantee consistent performance across multi-shift operations in demanding geotechnical environments.
Conical 30°–35° tip angle enables smooth soil displacement, minimizes vibration, and prevents premature bit deflection in layered strata.
Solid YK05-grade WC-Co tip (94% WC, 6% Co) sintered at 1450°C — no coating, no cladding, full bulk hardness retention under thermal cycling.
Vacuum-brazed joint (Ni-Cr-B alloy) tested to ≥1200 MPa shear strength — eliminates tip pull-out during high-torque rotary drilling.
Optimized for cohesive loams, clay-silt mixes, and riverbed deposits — maintains cutting edge integrity after >200 linear meters.
Resists rapid erosion from quartz-abrasive media; conical shape prevents sand packing and heat buildup.
Effective on shale, marl, weathered limestone (UCS ≤ 60 MPa) — delivers 3× longer life vs. standard flat-tip teeth.

BR1 teeth are engineered for direct replacement on Vermeer D27x30, D40x55, D60x70 series drill bits, as well as TerraVibe, Ditch Witch JT40/60, and custom OEM tooling with 15mm mounting pockets.
In controlled field trials on quartz-rich alluvial sand, BR1 achieved 3.2× longer service life and reduced torque variance by 41% — due to its self-cleaning conical profile and uniform stress distribution.
