2 IADC CODE REFERENCE- TRICONE BITS IADC 6 5 First Digit:,, and designate STEEL TOOTH BITS with for soft, for medium and for hard formations., 5, 6, 7 and 8 designate TUNGSTEN CARBIDE INSERT BITS for varying formation hardness with being the softest and 8 the hardest. Second Digit:,, and are further breakdown of formation with being the softest and the hardest. Third Digit: This digit will classify the bit according to bearing/seal type - see information on different bearing types - and special gauge wear protection as follows:. Standard open bearing roller bit. Standard open bearing roller bit, air-cooled. Standard open bearing roller bit with gauge protection which is defined as carbide inserts in the heel of the cone. Sealed roller bearing bit 5. Sealed roller bearing bit with gauge protection 6. Journal sealed bearing bit 7. Journal sealed bearing bit with gauge protection

3 Rock Bits - "Y"series Milled tooth, non-sealed, roller bearing, non-jet circulation Rock Bits Adapted to be equipped with light drilling machines its power rate is rather low Widely used in petroleum, mine and construction engineering Traditional products, high reliability, low price. 6 Y6 IADC Code : Adapted to be used in semi abrasive hard rock formations(hardsands, hard limestone, hard dolomite etc.) Types & IADC Code Parameters Y Y Y Y Y5 Y r.p.m Rock Bits - "P"series and "PB" series Milled tooth, non-sealed, roller bearing, jet circulation Rock Bits One of the main series in oil wells drilling. Liable to obtain higher drilling rate. With a long manufacture eperience, high quality products. Strengthen gage protection in "PB" series.

4 9 5/8 P IADC Code : Designed and manufactured for application with high pressure jet circulation, with reasonable and reliable structure, adapted to soft or medium soft rock formation drilling. Silver medal award was approved by National Quality appraisal Committee in 98.

8 Rock Bits - "XT"series "XTP" series Insert, sealed, floating journal bearing rock bits. New type bearing with two friction paris. Not only adapted to work under heavier drilling weight, but also higher rotary speed. For "XT" series with no-jet circulation For "XTP" series with jet circulation, and this is one of ther main series of insert rock bits 8 / XTP IADC Code : 57 Adapted to be used in low compressive strength and high drillability soft rock formations shale,clay,soft limestones etc). It is one of the proper bit type used in oil fields.
