100mm DTH Button Bit from DHD3.5 - 3'' High Air Pressure DTH Hammer

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

To Chose the Right Products

When selecting the right bit for optimum performance you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration, remember the rule of thumb that states that a 10% increase in penetration covers at least a 20% loss in bit life. our commonly hasthree basic bits head designs: Flat Face, Convex and Concave. These are designed for specific applications for all rock types, hardness’s and conditions:
