Welcome to Throop Rock Bit Company

Throop Rock Bit Company has a long and proud history in the drilling tools market. In 1947, Throop began servicing local oilfield and related markets with machining, tooling, and related components. In 1961, Throop manufactured its first roller cone rock bit. We quickly became the world’s largest manufacturer of the smallest diameter roller cone bits, with sizes as small as 1 7/8” in diameter. Although we have steadily increased our size range, one thing has never changed: Throop remains steadfastly committed to its goal of offering quality products, unparalleled service, and reasonable prices.
