X-bit button bits tend to
drill round holes in all rock conditions.
The steel support in the narrow parts of the X becomes inadequate
in X-bits smaller than *4 mm because of the restricted
circumference).
Where straight hole accuracy is required in hard, abrasive ground, blade bits of cross bit and X-bit are ideal, as they tend to resist gauge wear better than button bits. Generally, blade bits are not as productive and yield higher drilling costs than button bits. In addition, blade bits generally require more frequent sharpening than button bits because of the less wear resistant carbide grades on the face.
