摘要 |
The invention relates to a ground-engaging tool which is connected or connectable to a lip on an excavation bucket. The ground-engaging tool includes a tool body which is formed from a material having a hardness of approximately 40 Rockwell C hardness and which defines a contact surface at one end for receiving impacts in use. Extending through a substantial portion of the tool body from the contact surface is a hardened core formed from a material having a hardness which is at least 20% greater than the hardness of the material of the tool body for transferring impacts through t he tool body.
