Tigerrig MD Series High Speed Motor Bit

Production Description:

Working condition of the bit in directional and horizontal drilling applications is quite different than in vertical well drilling. King dream's MD series motor bit has structure features of metal face sealed, special cone shell protection, enhanced head O.D. protection and enhanced gage protection, so that MD bit is suitable for drilling in directional and horizontal well drilling applications.

1.MD series motor bit features high RPM, better gage protection and stability, higher reliability, excellent hydraulic effect and longer working life, etc.Working condition of the bit in directional and horizontal drilling applications is quite different than in vertical well drilling. King dream's MD series motor bit has structure features of metal face sealed, special cone shell protection, enhanced head O.D. protection and enhanced gage protection, so that MD bit is suitable for drilling in directional and horizontal well drilling applications.

2.MD bit is suitable for drilling at 300 ~ 90 RPM and is the ideal choice for directional, horizontal and horizontal multilateral well drilling applications.

3.The size range of MD series bit is 7 7/8 - 12 1/4 inches and its IADC code is 437 - 647.

Features:

1.Floating bearing and metal face seal

MD is designed with floating bearing and metal face seal structure suitable for high RPM. At the same time, it utilizes new type of synthetic lubricating grease to improve working condition of

the bit's bearing, so that the bit can achieve longer service life and higher reliability when used on screw drilling tools.

2.Higher ROP and longer working life

Highly efficient cutter shape and optimized cutting structure

The bit's ROP is greatly improved by using King dream's patented convex crested cutter shape and other highly efficient cutters.

3.To improve the bit's stability, prevent bit diameter shrinkage, and extend the bit's working life

Spiral double-stable head O.D.

Spiral double-stable structure can improve the bit's working stability effectively mitigate vibration of the bit at the bottom hole and improve outer flow field. This structure can facilitate the removal of drilling cuttings at the bottom hole and wall of the borehole and therefore improve drilling efficiency.

Enhanced gage protection

To meet specific requirement of directional and horizontal drilling applications, MD bit is designed with high density cutter placement that covers the whole head O.D. area and the cutter exposure changes in a ladder pattern so as to effectively protect the shirttail and seal and greatly improve the bit's ability against diameter shrinkage
