Product Description
American technology Polycrystalline Diamond Composite (PDC) with very high wearability, punching toughness, which is widely used for drilling stratum from soft to mid-hard (for example: Mudstone, petroleum shale, sand rock, lime stone and coal layer, etc...), low drilling pressure (about 4 tons ) to gain fast drilling progress ( 4-6 times of the hard alloy gear drill ) and high speed drill (2 times higher than hard alloy gear drill ) for exploration, mining, petroleum, coal industry and machining nonferrous metal and non-metal using the PDC knife.
