A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud ).

DTH drilling is often used in the mining industry (blast hole drilling), on construction sites, drilling water wells, and in the oil and gas industry. DTH drilling offers several advantages over top-hammer drilling for larger, deeper holes in medium-hard formations.

We offer a complete range of DTH drilling tools including hammers, bits, pipes, adapters, breakout benches and grinding machines with consumables.

Feb 4, 2025 · DTH drill bits are specialized tools designed to break through rock and other geology during drilling operations. They are attached to down-the-hole (DTH) hammers and mounted on drilling rigs to create boreholes for mining, construction, energy, and …

Dec 9, 2024 · Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation, and air.

Drill King manufactures the widest range of high quality Down the hole (DTH) tooling. From hammers, bits, shock absorbers, hole openers to casing systems and (WAI) water hammers and hole openers. Comprehensive range of DTH rock drilling tools for any tough environment.

In down-the-hole drilling a drill rod is fitted with a hammer at its lower end. The hammer, which is mounted on the drill bit, is activated through the addition of compressed air and driven into the ground – simultaneously rotating and impacting.

Dec 4, 2024 · DTH hammers are most used in hard rock formations and are designed to tackle complex tasks like drilling in populated areas without putting existing structures at risk. In these areas, they are ideal for drilling large diameter boreholes in hard rock formations, typically ranging from 3 inches (85mm) to 48 inches (1219mm) or more.

Jan 25, 2023 · DTH drilling is a drilling method that’s used to crush rock by using a drilling hammer to hit hard rock repeatedly. DTH drills are pneumatic tools that provide power by driving compressed air into a piston inside the hammer.

Dec 18, 2024 · Discover the benefits of large-diameter DTH hammer drilling technology. Achieve efficient, precise, and sustainable deep hole drilling for mining and construction projects.
