Product Description

NUMA100 10-inch DTH Drill Bits

High Manganese Steel Carbon Steel Rock Drill Bit for Hole Drilling

Product Features

Button bit features high wear resistance for medium-hard to hard abrasive rock formations (200-260 Mpa compressive strength)
Spherical tungsten carbide inserts provide strong configuration against carbide fracture
Recommended for eliminating hole deviation
Ideal for drifting and tunneling applications
Optimized bit face design for medium-hard to hard abrasive rock

Product Applications

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 projects. They offer advantages including high flatness, smooth hole walls, rigid drill rod and hammer construction, independent high axial thrust, unlimited drilling depth, low device costs, and easy maintenance.
