Company Overview
Established in 1947, Throop Rock Bit Company has continuously designed and manufactured rotary cone bits for more than half a century. The company began as a manufacturer of the smallest size rotary cone rock bits for water well and mining applications and has progressively increased the sizes and types available. Throop has since expanded its product line to serve all applications for rotary drilling bits – such as petroleum, mining, seismic exploration, water wells, quarrying, river crossings, foundation construction, and other industrial applications. Our staff is knowledgeable in the unique requirements specific to all these diverse applications.
Headquartered in Tonkawa, Oklahoma, USA, Throop Rock Bit Company designs, manufactures, and assembles all of its products in the United States using state-of-the-art technology, materials, and equipment.
The Throop Rock Bit Company plan is centrally heated and air conditioned for the comfort and efficiency of our shop work force. Throop’s skilled machinists, welders, assembly personnel and shipping staff are seasoned veterans in the rock bit industry who choose to live and work in a stable rural environment.
Our machinery and equipment includes state-of-the-art CNC machines tools. All bearing surfaces on our cones are finished and turned after heat treatment. All of our bits are assembled, greased and inspected in a special clean room area prior to welding and painting for shipment.
Throop rock bits are designed using both AutoCAD 2002 and Autodesk Inventor 2010 design and drafting software. Throop also utilizes a special rock bit design program developed specifically for the rock bit industry. This design system allows our engineers to more accurately design bits for optimum performance.
It is with these materials, manufacturing and design capabilities, and pride in workmanship that we are able to produce one of the finest lines of rotary drilling bits available in the sizes and types that we produce.
Throop’s products currently presented in this brochure range in sizes from 1 7/8” through 8 ¾” in both tungsten carbide insert type bits and sealed bearing bits. Most models are available in designs for either regular or jet circulation with replaceable nozzles. Most Throop open bearing models are also available for use with air or fluid circulation, and many sizes are available in reverse circulation.
