Impregnated diamond non-coring bit hole sizes are available in 56mm, 60mm, 76mm. The drilling portion of the non coring bit is unique for the matrix of it is impregnated with diamonds. The idea behind impregnating the diamonds within the drill bits is quite simple. Given that diamonds are prone to breakage from constant or prolonged impact and pressure, supporting them by protecting them with the noncorning bit provides a stronger solution.
