Feature
The floating bearing structure, floating element is made of new materials with high strength, high elasticity, high temperature resistance, high wear resistance characteristics is made, the surface of solid lubricant processing.At the same time reduce the friction surface temperature, can effectively improve the high speed drilling technology under the condition of bearing service life and reliability; High strength and high toughness cemented carbide teeth, high precision lathe technology and cold pressing technology have been used to improve the impact resistance of the teeth; Optimization design of the tooth row number, number of teeth, teeth height and unique alloy tooth shape, give full play to the cutting ability and cutting speed; Inner hole welding antifriction alloy bearing, improve anti bite ability; The high temperature of 260 degrees centigrade, the new grease and low wear, improve the ability of high temperature resistant sealing drill lubrication system.

We pushed this bit through extremely abrasive sandstone and it held up far better than others we've used, significantly reducing our downtime.
I was impressed by the bearing reliability—we got a clean, consistent run with no unexpected failures, which is crucial for hitting our target depth on schedule.
