Cutters

Cutters with cemented carbide buttons are easily mounted in the saddles. The cutters can be positioned in certain patterns to give different spacing between the rows of cemented carbide buttons in order to suit different rock conditions. Accordingly, large row spacing is used for boring in soft rock and narrow row spacing is used in harder rock formations.

Standard cutters for most conditions

Combinations of CMR-41 and CMR-52 cutters can normally be used for all conditions.

Flexible spacing

The use of two types of cutters permits the selection of row spacing depending on rock condition. Placing the cutters in a certain pattern results in narrow spacing; correspondingly, the pattern can be rearranged to provide double spacing. Patented attachment.
