The chisel variant of our J700 class tooth. At 72 kg it is built for 70 to 90 ton machines in blasted rock, where a narrow point helps the bucket bite into the pile instead of riding over it.
We keep the chisel web thick because a thin point on a part this size is a breakage waiting to happen under a full bucket load.
