Description: which is a matrix body PDC bit four to eight curved blades using arc-type ang short parabolic shape design, the rational allocation of different functions small size cutters,so that the PDC bit have a strong impact resistant, hyfrualic balance design, with each balde cuttting the amount of displacement is proportational to the volume of cutttings transports to match the PDC bit cutting transports capacity optimization. while using a dynamic flow simulation technlogy to optimize the hydraulic design of the PDC bit, so bottom hole flow field optimization, enhanced PDC bit cleaning, coolling capacity,more optimum bottom hle flow pattern and anti- balling. Medium hard to hard formations with high compressive strength and abrasive, such as shale, limestone, anhydrite, sandstone and so on The main structure features: Tungsten carbide matrix PDC possesses high wear resistance and impact resistance. Parabolic crown profile and maximizes junk slot area can clean bit better, and prolong the bit working life. Applying hydraulics balance design, 5 renewal nozzles and reasonable nozzles locating angle can gain ideal fluid field in well bottom, fully clean and cool cutter, and prolong the cutter working life. Non-symmetry blade arrangement enhances drilling well balance. Optimization for cutter shape, slant angle, cutter numbers prolong the cutter working life in combination with high quality PDC cutter, and improve ROP and drilling efficiency. It can be used on rotary or down hole motor. High HIS is recommended. Product Advantages: 1. PDC cutters for high speed drilling; 2. All cutters are premium grade for extended bit life and durability; 3. Cutter layout is force balanced to drill a precise round hole and reduce bit whirl; 4. Large junk slots and flushing ports; 5. Advanced geometric design for faster penetration; 6. Gauge pads have tungsten carbide inserts for maximum wear resistance;

Rock Roller Bits: Soft formation rock bits are used in unconsolidated sands, clays, soft limestones, redbeds and shale. Medium formation bits are used in dolomites, limestones, and hard shale, while hard formation bits are used in hard shale, mudstones, cherty limestones and hard and abrasive formations. Rock Roller Bits: Available Ranges: Tungsten Carbide Bits : 3 7/8" â?? 17 ¼" (98.4mm-438mm) Milled Tooth : 3 7/8" â?? 17 ¼" (98.4mm-438mm)
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*40*45 cm 50kg
