MIRACLE manufactures the finest and most efficient Down-the-Hole (DTH) hammers and bits for the mining, construction and water well industries. Drill and blast engineers and water well contractors trust Miracle’s DTH equipment because of the precision engineering and high standards of drilling efficiency built into each of our hammers and bits.
Highlights
1. Long life of dth bits: the wear ratio of cemented carbide is more than 10-20 times that of similar products, so the life is greatly extended;
2. High drilling efficiency: the hard alloy has high hardness and wear resistance, and the drill bit can always be kept sharp, thus greatly increasing the tooth feeding speed;
3. Wide range of application: Practice has proved that the drill bit is suitable for drilling in medium-hard formations such as carbonate rock, limestone, chalk, clay rock, siltstone, and sandstone.
4. Due to the fast drilling speed and long service life, the times of tripping and tripping are less, and the drilling cost is greatly reduced, which has excellent cost performance.
