API Single core bit / TCI single core rock bit

1.TCI single core bit 2.For water,ore mining ,oil well 3.OEM or according to your request 4.Suitable for sidetracking

YC Series single cone bit

1. Diamond enhanced carbide inserts are arranged on top of the cine of single cone bit to improve wear resistance for longer working life of the bit.

2. New type of hydraulic system enhances cone and bottom hole cleaning ability to assure higher ROP of the bit large diameter active cutting conical spherical inserts are used for gage protection on bit body, so that the bit has excellent gage holding and up-reaming abilities.

3. Single cone bit is suitable for slim hole drilling operations such as reentry and sidetracking operations.
