Abstract
The present disclosure is summarized as an improved cutting tooth for mounting on a stump cutting wheel driven by a suitable power plant. The tooth itself includes a long root to enable it to be clamped on the cutting wheel. When appropriately clamped, it is held with an extending neck terminating in a planar face. The face is constructed with an improved PDC hard surface layer. This is attached by a suitable WC-Co sintered alloy which joins the PDC layer to the tooth. This enables more certain anchoring of the PDC layer to the tooth. This enables more certain anchoring of the PDC face so that it does not break or flake during use and operation.
