The 40mm large-size tungsten carbide drill tooth is a customized engineering drilling tool developed for complex geological conditions such as pebble layers, gravel layers and boulder mixed strata. Different from conventional small-size drill teeth, this product adopts an enlarged and thickened tungsten carbide blank design with fully upgraded effective stress area and wear-resistant layer thickness of the carbide. It fundamentally solves the industry pain points of drill teeth such as easy wear, tooth chipping, carbide falling off and short service life during drilling operations in pebble strata. Compatible with rotary drilling rigs, pile drivers and foundation drilling equipment, it is widely used in building foundations, road bridges, pile foundation engineering, geological drilling and other scenarios, serving as a core wear-resistant accessory for efficient drilling in complex pebble strata.
Equipped with a standard 40mm carbide size, it features larger overall carbide volume and wider effective wear-resistant area compared with ordinary 30/35mm drill teeth. Made of high-purity tungsten-cobalt carbide raw materials and formed by high-pressure sintering and precision grinding technology, the carbide boasts high hardness, strong toughness, and greatly improved erosion and abrasion resistance. It can maintain a complete tooth shape for a long time under continuous friction and impact working conditions of pebbles, avoiding rapid wear, greatly extending single service life and reducing shutdown loss caused by frequent tooth replacement.
The structure is optimized for difficult-to-construct strata such as pebble layers, gravel layers, soil-rock mixed layers and boulder interlayers. The large-size carbide tooth head has stronger biting force, which can efficiently crush and strip dense pebbles and hard gravels, avoiding drilling jamming, hole deviation and slipping. Meanwhile, the tooth body stress structure is optimized to disperse the impact force of pebble collision, preventing tooth chipping and breaking, perfectly adapting to the harsh working conditions of various field infrastructure and pile foundation drilling.
