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 412 core bit has an overall diameter of 107.2mm or 4.22 Inches, with a coring (inside) diameter of 74.70mm or 2.940 Inches.
