Longyear engineers developed a new crown that consisted of synthetic diamonds evenly distributed throughout a composite matrix. This new design could drill further and faster than surface-set bits and cut through much harder material. By 1980, 75 percent of Longyear's Canadian-produced bits were of the new impregnated type, and Longyear was manufacturing diamond bits in more than eight countries.

726:. Meanwhile, Longyear expanded its Canadian business, which grew to $ 10 million by the end of 1967. This growth fueled new technological innovation, and in 1958 Longyear patented the first wireline core retrieval system, which increased productivity on worksites within the diamond drilling industry and made tripping core from the bottom of the hole safer for the drilling assistant. This system later became known as the Q Wireline System.
