Product Description
Advantages of new diamond dive drilling
The longer life of the drill: the alloy material, with longer using life which better than the similar products;
High Drilling Eficiency; the drill butons is wear-resistant, so that the drill can ahways 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 New Diamond bit has strong wear
resistance, good diameter pronection and can make the cutting teeth be used efficiently.
The use of a wide range: the practice proves that the bit is suitable for carboname rock. limestone, chalk, dlay rock, siltstone, sandstone and other soft and hard (9 - grade drillability of rock, hard rock drilling), compared with normal bit, especialy drilling in 6-8 grade rock the effect is particularly significant,
