Product Description

Product Description

Cross Drill Bit

Cross drill bit (also known as cross-blade drill bit, cross rock bit) is a highly versatile core rock drilling tool, specially designed for hydraulic/pneumatic rock drills. It adopts a structure of cross-symmetrically distributed cemented carbide cutting edges and high-strength alloy steel matrix, and is accurately connected to the drill rod through standard threads such as R38 and T38. It can efficiently adapt to various medium to hard rock formations such as granite, limestone and shale, realizing rapid drilling and rock breaking. Widely used in mining blasting hole drilling, tunnel excavation, slope anchoring, building foundation construction, geological exploration and other fields, it supports both dry and wet operation modes, with the core advantages of fast centering, sharp cutting and smooth slag discharge, greatly improving operation efficiency and construction stability.

Cross Drill Bit

Cross Slag Removal & Anti-jamming Efficiency:Optimized cross-shaped slag discharge channel, combined with streamlined groove design, the discharge speed of rock powder and gravel is increased by 30%, effectively reducing the probability of drill jamming and hole blocking, and the operation stability is greatly improved in fractured zones and wet drilling conditions.
Impact Resistance & Wear Durability:The matrix is made of 42CrMo alloy steel, treated with quenching and tempering plus carburizing and quenching. The cutting edges are made of tungsten carbide-based cemented carbide, with optional TiCN composite coating on the surface, which has excellent impact toughness and wear resistance, and is not easy to chip or wear during high-frequency impact operations.
