If less penetration is required, an alternative are steel knurled rollers. These roller are designed with small diamond-shaped points on the contact surface, with a maximum "tooth mark" indentation of less than 1mm (1/32") deep. As with the standard rollers, the contact surface is hard-chromed for long life.

For wet timber or difficult feeding, a very aggressive tooth pattern available only in 2" wide rollers is listed after the other types of feed wheels.
