LONGYEAR LARGE DIAMOND BITS LONGYEAR LARGE DIAMOND BIT SERIES Extreme Performance Our customers demand extreme performance. An exploration Copyright © 2020 Boart Longyear. All rights reserved. U.S. Patent No. 7,695,542; 7,975,785; AU 200 driller’s success depends upon his productivity and the performance of his drilling equipment. To meet this demand for extreme performance, Boart Longyear has improved the large diamond bit series. Boart Longyear presents, innovative diamond bit technology using advanced metallurgy and scientific research, resulting from more than 80 years of field experience. Large diamond bits have revolutionized mineral exploration. These bits drill faster, last longer, and perform in a wider range of drilling conditions and formations for those who can adjust their drilling parameters to them. The extended range and versatility of the diamond bits means less tripping out rods and more core in the box.

By combining patented technologies with customer collaboration, Boart Longyear’s engineers have designed the highest performing diamond bits available anywhere on the market today. Longyear Large Diamond Bits are highly versatile, capable of adjusting from one ground formation to another. They are also very durable, able to resist the wear and punishment of extreme ground conditions. They are our most productive bits ever with increased output, efficiency and performance, tested and proven at sites throughout the world. While drilling more like a surface set and requiring driller adaptation, for those who do, they promise the best available penetration and life, particularity in medium and large grained rock. GREY BIT The Grey Bit is based on the original Longyear Large Diamond Bit. Boart Longyear has improved the impregnated diamond bit with the performance and reliability required to replace traditional surface- set diamond bits. The large synthetic diamond increases penetration and bit life over the original larger diamond bit. Drillers report a minimum of 200% life over traditional surface-set bits. Many surface-set drillers never had a reason to leave their traditional technology behind for impregnated diamond bits — until the Boart Longyear large diamond bit. BLACK BIT Black Bit is about extreme penetration. Equipped with customer feedback and decades of experience and global testing, the Black Bit is our fastest penetrating, large diamond bit, featuring advanced technology for a free-cutting matrix good for use in medium to hard ground formations. This bit maximizes productivity and will become the new industry standard in performance. Copyright © 2020 Boart Longyear.

This safety record demonstrates the commitment to safety by our employees which has resulted in an industry leading performance. Jeff Olsen, Boart Longyear’s CEO commented, “With the support of our global workforce the Company was able to increase its EBITDA and Cash Flow from Operations on lower revenue. Like many in our industry we witnessed organic global demand decline through the second half which we attribute to the several significant mergers and acquisitions within the mining industry, which in turn delayed mineral exploration projects and reduced overall market activity.

  • EXPLORATION Edmund Joseph Longyear
    EXPLORATION Edmund Joseph Longyear Edmund Joseph Longyear founded the company EJ Longyear (which has now become Boart Longyear) in 1890 when he “inherited” an old abandoned diamond drill on the Iron Range in Minnesota. EJ Longyear His company basically invented contract diamond drilling and most of the drills and in-hole tools necessary to accomplish that expensive and necessary task. Many don’t realise that the company was also very involved in contract geological services, contract mining and shaft sinking in the early part of the 20th Century. Longyear’s company’s wireline-retrieved ‘Q’ core- barrel revolutionised the exploration business in the 1960s and is still the standard used in the business today (in only slightly modified form). This innovation so reduced the cost of drilling that it could be suggested that many deposits were able to be found and delineated with the funds saved versus the conventional methods of core sample retrieval. EJ Longyear’s historic first diamond drill site on the famed Mesabi Iron Range of Minnesota was the beginning of a new era in iron and mineral exploration, and, under his technical direction, the Mesabi Iron Range became one of the largest regional areas of diamond drilling the world has ever seen. In 1888 Longyear was a member of the first graduating class of Michigan College of Mines in Houghton. Later that year, he directed exploration and diamond drilling for his cousin, JM Longyear, on the eastern end of the Menomonee Range in Michigan. This was his first connection with diamond drilling. In the meantime, reports were coming in from northern Minnesota of the possible existence of a new iron range, and, on May 22, 1890, EJ Longyear arrived at the Mesabi Range.
