1. High and low air pressure down-the -hole drill bits.
2. Low air pressure hole Dia.: 65-220mm.
3. High air pressure hole Dia.: 85-305mm.
4. Face type: concave/ convex/ flat.
5. Bit Shank Series: COP, DHD, QL, SD, Mission, TD, BR etc.6. Button Shape: Dome/ Spherical, Balistic.We can design and manufature according to your requirment of diameter, number air holes and carbide button shapeProduct Feature: 1.The longer life of the drill: the alloy material, with longer using life which better than the similar products.
2.High Dilling Eficiency: the dril buttons is wear-resistant, so that the drill can always keep sharp thus greatly improving the speed of the drllng.
3.The driling speed is stable:the bit is scraped and cut to break the rock. 4.Good Performance: bit has strong wear resistance, good Diameter protection and can make the cutting teeth be used efficiently.
