The longer life of the drill: the alloy material, with longer using life which better than the similar products;
High Drilling Efficiency: the drill buttons is wear-resistant, so that the drill can always keep sharp, thus greatly improving the speed of the drilling.
The drilling speed is stable: the bit is scraped and cut to break the rock.
Good Performance: the Blurbly bit has strong wear resistance, good Diameter protection and can make the cutting teeth be used efficiently.
The use of a wide range: the practice proves that the bit is suitable for carbonate rock, limestone, chalk, clay rock, siltstone, sandstone and other soft and hard (9-grade drilability of rock, hard rock drilling),compared with normal bit, especially drilling in 6-8 grade rock the effect is particularly significant.
