Tungsten Carbide Rock Drill Bits Through Reverse Circulation Drilling Bit
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.
• Medium to large size drilling diameters
• Works in high pressure range, capable of drilling deep hole
lengths
