Work in High Pressure,3''4'' 5'' 6'' 8'' DTH bits ,dia 85-305mm,In the Hole Drilling Tools
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.DTH bits are paired with their corresponding hammers (by drilling hole diameter and spline configuration). Customers can customize their DTH bits in various ways, such as changing the tungsten carbide insert profile (spherical, ballistic, etc.), face profile (flat face, concave, convex, etc.), and flushing holes.
1,DTH drills use more in open-air large diameter drilling projects.
2,DTH drill bit owns stable performance,easy to grind,most of the current DTH drills use spherical spline tooth-shaped head and caudal peducle.
3,Carrying capacity,good wear resistance,fast
4, Color: Green,Blue or Based on Customer requirements
