Product Application

DTH hammers and bits are widely used in underground mining, quarries, hydraulic and hydro-power engineering, water well drilling, mineral exploration, anchoring hole drilling, geothermal engineering, subway excavation, and other civil engineering applications. They offer advantages including high flatness, smooth hole walls, high rigidity of drill rod and hammer, independent high axial thrust, unlimited drilling depth, low device costs, and easy maintenance.

Key Features

Button bit provides high wear resistance on medium-hard to hard abrasive rock formations (200-260 MPa compressive strength) with spherical tungsten carbide inserts for strong configuration against carbide fracture
Recommended for eliminating hole deviation
Ideal for drifting and tunneling applications
Bit face design optimized for medium-hard to hard abrasive rock
