Product Description

Product Introduction
Down-the-hole (DTH) 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. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes.
DTH drilling has the feature of efficiency and flexibility.  It's a commonly used method in the mining industry (blast hole drilling), waterwell drilling, construction, and in the oil and gas industry. In DTH drilling, the drill string rotates while the drilling hammer continuously strikes down into the rock.Inside the hammer, a piston powered by compressed air gives the drill bit its striking power. This combined with the rotational movement means the rock is crushed in a very efficient manner.

Product Adavantages
1. Long life of bit: alloy steel material has a long service life, which is higher than similar products.
2. High drilling efficiency: the drill teeth are wear-resistant, so that the drill bit can always be sharp, thus greatly improving the entering speed of the teeth.
3. Steady drilling speed: the drill bit breaks the rock by scraping and cutting.
4. Good spacing effect:  strong abrasion resistance and good spacing performance, which enables the cutting teeth to be utilized efficiently.
