We also have a sizable inventory of new surplus bits that are . Supplied as Milled Tooth Bits or Tungsten Carbide Insert ( TCI) bits to suit varying rock formations. Circulation type may be regular flui jet or air blast. Refurbished rock bits are also available from time to time and your enquiries are welcome. Using diamond inserts in traditional rock bits can boost performance, increase durability, and dramatically improve drilling economics. Diamond-enhanced rock bits also make it possible to drill formations that are too difficult for traditional tungsten carbide inserts.

This type has the best bearing performance of all the bit bearing types manufactured by TSK. As this floating journal bearing is designed using bearing metal having excellent anti-galling.

Co content = 8– WC grain size = 5–μm Cutting tools are not recommended.

The basic concept requires the fol- lowing torque equation that is a function of weight on bit. Hughes patented the first rotary rock bit , which he called a “boring drill.

The drill resembled two pipe reamers set on journal bearings attached to a drillpipe sub. This invention enabled rock formations to be drilled and was the starting point for years of rock – bit de- velopment. A rock-drilling machine to facilitate full-scale drilling experiments has been built. The machine uses a sixinch tricone roller bit to study the dynamics of the rock – bit interaction.

This process is not well understoo and there is a definite need to establish criteria for drill-bit wear and for the directional stability of the drill bit. Massenza MIand MIwith the Rockbit Service Support Vehicle.
