The tooth is compatible with original Komatsu buckets adapted for bolt-on teeth (hole spacing should be verified).
The tooth is mounted using plow bolts with nuts. We recommend replacing the bolts with new ones every time teeth are changed to ensure secure fastening (bolt hardness class min. 10.9).
Working with loose teeth leads to ovalization of the holes in the bucket blade. This can result in permanent damage to the bucket and the need for costly blade regeneration. Regularly check bolt tightness.
Bolt-on teeth serve as a replaceable cutting edge. They facilitate bucket penetration into the ground and protect its permanent structure.
