YC Series Roller Cone Drilling Bits
Y C Series single cone bit
This series of bit is suitable for slim hole drilling operations such as sidetracking and reentry operations.
The size range of VC series bit is 3 1/2 – 6 1/2 inch and its IADC code is 437 – 637.
Main structure features:
With particular structure of the cone, equal worn of the compacts in permanent contact area and alternative contact area of the bit is realized
Wear resistance of the cutting structure is enhanced by setting PDC cutters in the permanent contact area of the cone where compacts are most severely worn.
Optimized hydraulics structure improved the cleaning ability of hydraulic system on cone and bottom hole, and assure higher ROP.
The bit has excellent gage protection and up reaming abilities by setting active culling conical spherical gage compacts on head body
