2021 Good Quality Retractable Drill Bit - Mission 40 50 60 down the hole rock drill button bit price – TDS
2021 Good Quality Retractable Drill Bit - Mission 40 50 60 down the hole rock drill button bit price – TDS Detail:
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.
Color: Green,Blue or Based on Customer requirements
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.
