our product has a range of trenching tools that are suitable for a wide variety of cutting conditions. The cutting tooth SB 38 J is suitable for excavating clay, cobbles (diameter greater than 50 mm), sand, weathered rock and hard rock. The tungsten carbide of the JM type tooth, when compared to the JMK Type, is bigger and therefore more efficient in crushing boulders. The JL and JR Type are mounted at the outer edges of the cutting wheels to ensure the necessary over-cut. The tungsten carbide is hard and tough. |
