ATS cone bit for slim holes has improved service life and security of bit, and decreased round trip times, therefore, realized the purpose of increasing drilling speed and decreasing drilling cost. ATS cone bit for slim holes is with the feature of ATS high speed motor bit, and designed with special bearing seal structure and oil storage system, tooth material, cutting structure and formation lithology are matched reasonably to solve the problems of low efficiency and tooth break & fall while drilling in complex formations.

ATS cone bit for slim holes is the ideal choice for slim-hole section drilling in deep well and super-deep well. In addition to the leatures of ATS motor bit ATS slim hole bit is also designed with special bearing & seal structure and lubrication system ATS bit's cutter material and cutting structure  are reasonably matches with rock properties of the formation and this eliminated the specific problems such as low drilling efficiency and cutter breakage and loss, etc.

ATS  slim hole bit has structure features of metal face sealed and enhanced head 0.0. protection, so that the bit is suitable for drilling slim hole and ultra-deep well drilling applications.

ATS slim hole bit is the ideal choice for drilling slim hole sections in deep and ultra-deep well drilling applications.

The size range of ATS series bit is 5 3/4 - *1/2 inch, such as 5 7/8, 6, 6 1/8 and its IADC code  is **7 - **7, such as **7,**7, **7, **7, **7, **7, **7, **7, **7.
