Our PCD coring bits are engineered to the highest possible quality. Due to the polycrystalline diamond cutters set on the crown they have a long working life, very fast penetration rates and high percentage of core recovery in soft through to hard rock formations. PCD bits are a great alternative to T.C bits and Surface set diamond bits, when drilling in non-consolidated and medium/hard rock formations. PCD bits may be used with air, mud or foam flushing.

The PWL Long core bit has an overall diameter of 120.78mm or 4.755 Inches, with a coring (inside) diameter of 92.33mm or 3.635 Inches. The long barrel size makes PWL Long bits one of the most effective ways of extracting and retaining lengthy and sturdy sample sizes.

Drill-Its Griffin PCD set of drill bits are our range of Set To Liner PCD models, meaning the casing string that does not extend to the top of the wellbore, but instead is anchored or suspended from inside the bottom of the previous casing string. There is no difference between the casing joints themselves.
