Cat dozer cutting edges provide the best balance of abrasion and impact resistance. Both Cat cutting edges and end bits are designed as a balanced system to move more material over a longer period with less downtime. This is accomplished by providing great strength for superior breakage resistance, and by offering maximum wear protection from both bottom and face wear on the cutting edge.
