The XMW series bits are non-sealed Roller Bearingbits,which are ideal and economicaltools for high-speed drilling and geothermal well drilling.


Bits of 20 and above adopt a roller-ball-roller-roller structure.


9 ½ - 17 ½  bit bearing adopts a roller-ball-roller-thrust structure.


Bit bearings below 8 1/2 of the bit adopt a roller-ball-small shaft-sliding thrust structure.suitable for high rotational speeds.


The bit bearing is not sealed, and the drilling fluid directly enters the bearing cavity to coolthe bearing,making it suitable for geothermal well drilling.
