PDC material roller drill bit conical mining triangular drill bit
Product Information
note
The HY-TLI series bit is an O-ring rubber sealed roller bearing bit, which is an ideal and economical tool for high drilling speed
drilling. The main structural features are:
1. The rolling seal bearing structure places the cylindrical roller element in the groove of the tooth wheel body, increasing the
size of the journal, thus having the ability to withstand high drilling pressure and adapt to high rotational speeds;

1. The rolling seal bearing structure places the cylindrical roller element in the groove of the tooth wheel body, increasing the
size of the journal, thus having the ability to withstand high drilling pressure and adapt to high rotational speeds;
2. The surface of the thrust bearing pair is subjected to wear reduction treatment and hardening treatment respectively, which
improves the bearing capacity of the bit and the anti bite ability of the bearing;
improves the bearing capacity of the bit and the anti bite ability of the bearing;
3. The use of a new type of lubricating grease that can withstand high temperatures of 250 degrees and resist wear has improved
the high-temperature resistance of the bit sealing lubrication system;
4. The inset bit adopts high-strength and high toughness hard alloy teeth, which improves the impact resistance of the teeth and
reduces the rate of tooth breakage; Welding wear-resistant materials on the surface of steel tooth bits, optimizing the welding
position and thickness of the bit teeth, and further improving the wear resistance of the bit;
5. The optimized design of the number of teeth, number of teeth, exposed tooth height, and unique alloy tooth shape fully
utilizes the cutting ability and cutting speed of the bit.

Features
1. The use of high-strength and high-toughness carbide teeth improves the impact resistance of the teeth and reduces the rate of
tooth breakage;
2. Optimized design of the number of teeth, the number of teeth, the height of the exposed teeth and the unique alloy tooth shape,
give full play to the cutting ability and cutting speed of the drill;
3. The circlip is used to lock the roller, which can withstand high drilling pressure;
4. The inner hole of the cone is welded with anti-friction alloy to improve the anti-seizure ability of the bearing;
5. The use of highly saturated nitrile rubber O-ring seals, optimized seal compression to improve the reliability of bearing
seals;
6. The all-rubber oil storage bag that can limit the pressure difference and prevent the drilling fluid from entering the
lubrication system provides good lubrication for the bearing system and ensures the normal operation of the "O"-shaped sealing
ring, which improves the working life of the drill bit;
7. The use of a new type of grease that can withstand high temperatures of 250 ℃ and low wear improves the high temperature
resistance of the drill bit sealing lubrication system.
