JESSIN ROCK DRILL CO.,LIMITED, www.dthhammer-js.com PDC drill bits use PDCs as main cutting media, with the excellent wear-ability and impact toughness of the PDC. It has a long service life, high-efficiency, and good cost performance. PDC bit is mainly used for drilling soft and medium hard rock, and it must work under low drilling pressure, mid-low speed and big drainage. JESSIN can supply all kinds of PDC core and non-core bits, PDC sintering matrix bits and PDC anchor bits. PDC bit can be widely used in the fields of geological exploration, coal mining, water conservancy and hydropower, construction of road and railway. We also can design PDC bits according to customer requirements, such as different geology conditions, special strata and so on. Features 1. Super long service life. The service life of PDC bit is as much as 4~5 times than diamond bit, at least 10 times than tungsten carbide bit. 2. High drilling speed. 3. Can be operated with low pressure and speed. 4.Has a good gage protection. 5.Used widely, more suitable for drilling in the stratum with hardness coefficient f

1.The description of PDC Bits PDC Bit uses PDC as main cutting components, with the excellent wear-ability and impact toughness of the PDC. It has a long useful life, high-efficiency, and good performance cost ratio. PDC bit is mainly used for drilling soft and medium formation, it works under low drilling pressure, medium-low speed, big drainage. We can supply all kinds of PDC Core drill bits and non-core drill bits and they are widely used in the fields of geological exploration, coal mining, water conservancy and hydropower, construction of road and railway and provide reliable data support for drilling rock and coal of geology and engineering research. We can also design PDC bits according to customers' requirements, such as different geological condition, special strata and so on. PDC (polycrystalline diamond compact) drill bit is produced with special high-frequency welding techniques and manufactured by welding PDC of high wear resistant Si to the steel body as cutting edges. 2.The Features of PDC Bits: A: Super long life. The grinding/consumption ratio of PDC is 20-40 times that of tungsten carbide bit and 10 times that of diamond bit. B: High drilling speed. C: Can be operated with low pressure and low speed. D: Has a good gage protection. E: Can be used widely, more suitable for drilling in the stratum with formation< 7. F: Low cost. G: High toughness and impact strength

PDC bit.

1.Tighten the bits when screw on. 2.When the bit lower down to the bottom , Should give a soft pressure, slow drilling .After a drilling 0.2m-0.3m with appropriate pump, then give the conventional drilling. 3.Drilling could not be without water, if not fear the normal vibration sound or drill too slow, lift the drill to check without delay. 4.When drill jammed, withdraw first, should not to force the rig start. 5.Drill could not without water, to ensure that the bit will be too hot. 6.Use the bits in right order , big size first, then small one . 30*35*40cm 45kg
