Abstract
The systems and components described herein relate to ground engaging tools configured to attach to a digging bucket of a machine. The ground engaging tool includes a cast body formed of a cast material and having a proximal end including an interface for releasably coupling to the digging bucket, and a distal end having a first shape configured for digging into material. The tool also includes a preform cast within the cast body, the preform having a second shape corresponding with the first shape and sized to fit within the distal end, positioned within the distal end at a first depth from a surface of the distal end, and formed of a wear resistant material.

A ground engaging tool configured to attach to a bucket or blade of a machine, the ground engaging tool comprising:
- a cast body formed of a cast material and having:
- a proximal end comprising an interface for releasably coupling to the machine;
- and
- a distal end having a first shape configured for penetrating into material;
- a preform cast within the cast body, the preform:
- having a second shape corresponding with the first shape and sized to fit within the distal end;
- positioned within the distal end;
- and
- formed of a wear resistant material.
A ground engaging tooth comprising,
- an adapter at a proximal end of the ground engaging tooth configured for attachment to an edge of a ground engaging implement;
- a ground engaging tip at a distal end of the ground engaging tooth, wherein the ground engaging tooth comprises a cast body component having a first profile from the proximal end to the distal end;
- and
- a preform cast within the cast body, wherein the preform:
- has a second profile corresponding with the first profile and sized to fit within the ground engaging tip at a first depth;
- and
- is formed of a wear resistant material.
A ground engaging tool component comprising:
