Standard geometric data is based on published industry values as described under the International Standard for ISO 10097-2. Some of the recorded values are calculated by TDS Engineering Department. The care and handling, as well as drilling conditions, practices and equipment used, will also play a significant role in the ultimate capacity and performance.
