Tricone Bit/tricone Drilling 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

The used tricone bits are much more cheaper than the new ones because of the cost is low, but the quality is promised. 30*35*40cm 45kg

Product Description: Steel teeth Bits 114-117, 127 Soft Formation Tooth Bits The 114-117 bits are used to drill low-compressive strength, soft formation. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear. On the softest bits type this hard facing completely covers the bit teeth. 127 Medium-Hard Formation Tooth Bits The 127 bits are used to drill high-compressive strength, medium hard formations. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear. Medium hard with high compressive strength and hard streak (hard shale ,sandstone , limestone, etc.) 437 Soft Formation TCI Tricone Bits The 437 TCI bits are used to drill low compressive strength, very soft formations. TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, result in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations. 517 Medium Formation TCI Tricone Bits The 517 features aggressive chisel tungsten carbide insert on the heel rows and inter rows. This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard for-mationes. The HSN rubber O-ring provides adequate sealing for bearing durability. 637 Hard Formation TCI Tricone Bits The 637 bits can be used to drill hard and abrasive forma-tions. Wear-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-durability and long life. 617 Medium-Hard Formation TCI Tricone Bits The 617 feature robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fest drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-rin provides adequate sealing for bearing durability. Plywood case or according to the conform order.

TRICONE BITS : tricone drill bit is used when working with soft rock formations. Tricone drill bits that are ideal for soft rock formations will have long protruding teeth. They are also used to drill medium rock formations which include dolomites, hard limestone, and calcites. Core Bits APPLICATIONS:- ->Glass ->Ceramics ->Tile ->Rock and stone ->Granite and marble ->Concrete ->Masonry products ->Hard metals

China Factory Supply Mining Drill Bits Rock Drilling Tricone Bits For Hard Rock Product Descriptions Tricone bit is an ideal solution for soft, medium, or hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.
