ProDrill Threaded Drill Bit Advantage:Top hammer drilling bits are designed for extended wear life. In addition to this, you benefit from great versitality, higher penetration rates, straighter holes and longer bit life. ProDrill exceptionally versatile series of threaded botton bits, from28-152mm in diameter,are made from proprietary grade ofcemented carbide throughout ProDrill provides all the most efficient.
We will choose to use tungsten carbide of T6,featuring good wear-resistance and toughness.
This type of carbide has already been proved to be the best in world and been competing with those big names worldwide for quite a long time.
Meanwhile,we will choose to use superior steel suitable for hot insertion technology, by which the drilling bits body will hold the carbide buttons so tightly that reduce the risk of buttons’ dropping out of the holes.
In order to better resist the abrasiveness of rock, spherical shape will be a good option for the carbide if high speed is not a necessity.
