single Tube Bit

This series impregnated core bits are designed for sustainability and cost efficiency.

Product Description

This series impregnated core bits are designed for sustainability and cost efficiency. The bits are adjusted to fit slower rotation and heavy duty site-investigation rigs. They are less sensitive to abuse, rough handling and abrasive formations. A range of standardized matrices and one diamond impregnation height cover the most common applications. For site investigation and core drilling in shallow formations of less than 150 m (500 ft), this series impregnated core bits will be your optimal choice.


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
