Base on the high wear resistance and impact resistance of carbide buttons and high-performance steel, Maxdrill produces the tapered drill bits with higher driving efficiency, longer service life, better powder exhausting and easy bit back by optimizing the design of the powder-exhausting and flushinghole. The tapered drill bits with diameter 38mm, 36mm and 42mm are widely used in mining and tunnel construction, with the advantages of higher driving efficiency, better powder exhausting, better anti-wear and anti-impact and without grinding, which are ideal substitute for cross bits and chisel bits. we will concentrate to replace chisel bits with our patented tunneling and promote the drilling bits for tunneling.
