Характеристики

1,The optimized design of the number of tooth rows, number of teeth, exposed tooth height and unique alloy tooth shape give full play to the cutting ability and cutting speed of the drill bit;

2,The circlip is used to lock the gear wheel, which can withstand high drilling pressure

3,The inner hole of the cone is welded with anti-friction alloy to improve the anti-biting ability of the bearing;

4,Using highly saturated nitrile rubber O-ring seals, the optimized sealing compression improves the reliability of the bearing seal;

5,The use of an all-rubber oil storage bag that can limit the pressure difference and prevent drilling fluid from entering the lubrication system provides good lubrication for the bearing system, ensures the normal operation of the "O" ring seal, and increases the working life of the drill bit;

6,The use of new grease that can withstand high temperatures of 250°C and has low wear improves the high temperature resistance of the drill bit sealing lubrication system.
