Downthehole (DTH) bits are used with Downthehole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a splined drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes.
A downthehole drill hammer comprising: a sleeve (10) defining a cylinder a piston (12) reciprocable within the cylinder and arranged to operate a bit (26) percussively a shank (20) reciprocable axially relative to the sleeve (10) and having a first end (22) within the sleeve engagable by the piston, and a second end (24) extending beyond the sleeve and adapted to receive the bit the down
A "DowntheHole" Hammer is probably the most important component on the drill rig and the DTH system holds many advantages over other alternatives, for instance: Rotary Drilling is fine for large diameter holes in softer more friable rock but less effective in hard
Downthehole hammers – when proven technology is required. Our hammers are purposematched for all rock types and appliions. Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for
Feb 11, 2020 · A downthehole hammer (DTH hammer) is a tool that can be attached to the end of a drill string and inserted into a bore. As the market leader in downthehole hammers, Epiroc take the global market share of over 21%, other key manufacturers include , Mincon, Robit, Borat Lonyear and Rock Hog, etc.
As a rule of thumb, the smallest hole diameter a DTH hammer can drill is its nominal size. i.e. standard 102 mm (4") hammer will drill a hole down to a minimum diameter of 102 mm (4"). The limiting factor is the outside diameter of the hammer, because as the hole diameter reduces due to diameter wear of the bit, airflow is restricted.
