The Throop Rock Bit manufacturing facility in Tonkawa, Oklahoma where our bit products are made, holds the following certifications:

    Quality Certifications

    ISO 9001

    This standard specifies requirements for a quality management system when an organization needs to demonstrate its ability to consistently provide products and services that meet customer and applicable statutory and regulatory requirements. It also aims to enhance customer satisfaction through the effective application of the system, including processes for improvement of the system and the assurance of conformity to customer and applicable statutory and regulatory requirements.

    ISO/TS 29001

    This standard specifies requirements for organizations working within the oil, gas and petrochemical industry supply chain. ISO/TS 29001:2011 provides additional requirements to ISO 9001 specifically intended for petroleum, petrochemical and natural gas industries. For organizations within the oil and gas industry supply chain, certification to ISO/TS 29001 represents a significant opportunity for standardization and improvement. First published in 2003, it was developed by ISO and the international oil and gas industry, led by American Petroleum Institute (API).

    Our certifications have been in place since March of 2005. Throop Rock Bit ensures future quality success through a thorough internal audit process as well as annual registration audits which are performed by third party international registrars.

  • Each of our products is inspected several times throughout the manufacturing process. These inspections are performed by highly qualified inspectors that are independent of the day-to-day manufacturing process. This independent inspection process provides another layer of control, which ensures delivery of the highest quality product to our customers.

  • Throop Rock Bit is committed to meeting our customers' expectations and requirements through quality, service, reliability and continual improvement of all processes. As our customers' needs change, we adapt through constant monitoring of international standards and communicating with our customers.
