Application: drilling, exploration, petroleum and trenchless as pilot bit.
TCI bit adopts high-strength and high-toughness hard alloy teeth, optimized design of tooth row number, tooth number, tooth exposure height, and unique alloy tooth shape, giving full play to TCI bit's high wear resistance and excellent cutting ability.
Steel tooth bit, which can maintain the high penetration rate of the Steel tooth bit and improve the life of the cutting tooth of the bit. Steel tooth drills are suitable for extremely soft formations with low compressive strength and high drill ability such as clay, mud stone, chalk, etc..
Product Description:
Application: drilling, exploration, petroleum, and trenchless as pilot bit.
TCI((tungsten carbide insert) ) bit
TCI bit adopts high-strength and high-toughness hard alloy teeth, optimized design of tooth row number, tooth number, tooth exposure height, and unique alloy tooth shape, giving full play to TCI bit's high wear resistance and excellent cutting ability.
Steel tooth(MT Bit, milled tooth) Bit
Steel tooth bit, which can maintain the high penetration rate of the Steel tooth bit and improve the life of the cutting tooth of the bit.
Steel tooth drills are suitable for extremely soft formations with low compressive strength and high drill ability such as clay, mudstone, chalk, etc.
Features:
Tricone Bit-High strength and toughness carbide teeth are adopted to improve the impact resistance of teeth and reduce the rate of broken teeth;
Optimized design of tooth row number, tooth number, exposed tooth height, and unique alloy tooth shape, giving full play to the cutting ability and cutting speed of the tritone rock bit;
The clamping roller is adapted to withstand high drilling pressure;
Insert and weld the grinding gold in the inner hole of the roller to improve the anti-bite ability of the bearing;
The use of a highly saturated nitrile rubber O seal ring, the optimization of sealing compression to improve the reliability of the bearing seal;
Adopt an all-rubber oil storage capsule that can limit the pressure difference and prevent drilling fluid from entering the lubrication system, provide good lubrication for the bearing system, ensure the normal operation of the "O" seal ring, and improve the working life of the drill bit;
Adopt a new grease with a high-temperature resistance of 250℃ and low wear to improve the high-temperature resistance of the bit sealing lubrication system.

The 114-117 bits are used to drill low-compressive strength, soft formations. 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 bi types this hard facing completely covers the bit teeth |
