QL120-349mm Rock Drilling Equipment Tools Dth Drilling Button Bits


Description

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.
