Core Product Parameters
|
40mm Cemented Carbide Drill Teeth
are professional drilling accessories custom-engineered for complex pebble layer, gravel layer, and mixed stratum construction scenarios. Different from ordinary single-alloy drill teeth on the market, our
drill teeth
adopt an upgraded reinforced structure, equipped with standardized 40mm integral hard alloy cutting teeth as the core drilling part, paired with
3 built-in cemented carbide side protection strips
on the tooth body, which comprehensively solves the problems of rapid wear, edge chipping, and short service life of drill teeth in high-abrasion pebble stratum drilling operations.
The tooth body substrate is made of high-strength alloy steel with integral heat treatment process, featuring sufficient toughness and impact resistance without deformation. Adopting high-precision vacuum brazing technology, the carbide is closely combined with the substrate with uniform and firm welds, preventing carbide falling off under heavy-load operation. The standardized 40mm size has strong universality and easy installation and disassembly, compatible with mainstream rotary drilling tools on the market without modification, greatly reducing engineering consumable cost and construction time cost.
Widely used in building pile foundation engineering, bridge and road foundation construction, municipal infrastructure drilling, field geological exploration, photovoltaic and wind power foundation drilling, foundation pit support drilling and other scenarios. It is the preferred wear-resistant drill tooth accessory for complex strata with frequent pebbles, helping projects achieve efficient construction and cost reduction and efficiency improvement.
