Down-the-hole (DTH) hammer bits are used with Down-the-hole 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.
A down-the-hole hammer (DTH hammer) is a tool that can be attached to the end of a drill string and inserted into a bore. It's a small jack hammer used to break hard rock into small particles that can be flushed away by the DTH hammer's air exhaust.

With down-the-hole hammer drilling, the drill principle consists of a combination of percussion and rotation. Unlike the top hammer, here the hammer drill is located directly in the borehole. These devices, known as 'down-the-hole hammers', are connected to the rotating drill pipes.
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.

The primary difference between the top hammer and down-the-hole drilling methods is where the hammer is attached. The hammer in the industrial equipment makes contact with the bit during the down-the-hole drilling method. The top hammer drilling …
Hammer Equipment When percussion or hammer drilling the percussion mechanism is called a DTH or down the hole hammer. This drilling tool is located directly above the downhole hammer bit. The driller transfers weight to the bit through the drill pipe as well as provides some rotation. Through the use of a compressor, the pressurized air is ...
The bit is the tool cutting the rock, and no hammer or rig drilling is better than the bit it uses. The down-the-hole bit is subject to severe stress from the striking piston as well as from the abrasive cuttings passing the bit at high velocity.
Down-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs.
The history of the down-the-hole hammer manufacturing goes back more than four decades. For the past 40 years and still today, our goal is to produce the best products for our customers. Customers have been the key focus for the down-the-hole team throughout the years.
