Wholesale API rotating head for petroleum drilling rig in stock with discounted price from China factory
IADC: 215 is for medium to medium hard formations with high compressive strength.It is steel tooth sealed roller bearing bit with gauge protection.
The ground details is for soft,unstratified,poorly compacted rocks ,including sand stones,marl limestones, poorly compacteds clays,gypsum,salts and hard coals.
The tricone bit is an important drilling tools.The function of tricone roller bit has impacting,crushing and shearing and bearking the stratum rock when the roller cones rotates.Therefore,the tricone roller bit can adapt to various soft,medium and hard stratums.
