Product Description

single Tube Bit

This series of impregnated core bits is designed to be sustainable and cost effective. Adjust the bit to accommodate slower rotation speeds and heavy duty field stations. They are less sensitive to abuse, rough handling, and abrasive formations. A range of standard matrices and a diamond impregnated height are available for the most common applications. For field investigations and core drilling in shallow formations of less than 150 m (500 ft), this series of impregnated core bits is your best choice. We are Diamond Tools Manufacturer.

FEATURES&BENEFITS

* Less sensitive to abuse for high sustainability and cost efficiency

* Matrices for a wide range of formations, easy bit selection

* Standardized design makes the bit range competitive and cost effective
