Description

BETEK series bullet teeth are high-performance tungsten carbide-tipped cutting tools designed for foundation drilling, piling, and mining applications. These round shank cutter bits are engineered to deliver exceptional wear resistance, impact strength, and drilling efficiency across a wide range of ground conditions—from soft soil and sand to weathered rock and hard rock formations up to 100 MPa. The series comprises multiple models, with C31, BTK03, BTK10, and BTK70 being among the most widely used configurations for rotary drilling rigs, augers, and drilling buckets. Their robust construction and compatibility with major OEM systems make them a preferred choice for infrastructure and construction projects worldwide.

In the fields of pile foundation engineering and geotechnical construction, drilling efficiency is closely linked to the quality and suitability of the cutting tools at the front of the drill assembly. Our factory’s series of bullet teeth—including the C31/BTK03, BTK10, and BTK70 models—are specifically engineered to handle the diverse and complex geological conditions encountered in modern pile foundation and rotary drilling projects.

Our drilling tools are more than just replacement parts; they effectively convert the drilling rig's power into efficient, smooth cutting force. Featuring high-strength alloy steel shanks and sintered tungsten carbide tips, each model is optimized for specific applications, ensuring superior performance whether drilling through loose overburden or hard rock strata.

Application

Precise Asphalt Removal:Milling can be performed in layers (depth adjustment from 0-30cm) to remove rutting, cracking, and bumps.

Concrete Roughening:Creates a uniform texture (3-5mm depth) on existing concrete pavement to improve overlay adhesion.

Pavement Smoothing:Eliminates bumps, ripples, and other unevenness with an accuracy of ±2mm/3m, preparing for new asphalt paving.

Road Marking Removal:Precision milling of old road markings.

Airport Runway:High-precision surface treatment.

Typical Applications:Highway Maintenance: High-speed nighttime milling (operating speed 5-15m/min) to minimize traffic disruption. Municipal road reconstruction: Utilizing recycling technology, 100% recycling of old materials is achieved.

Airport runway maintenance: Special alloy teeth are used to handle high-strength concrete, with milling depths up to 50mm.
