Abstract
Implementations of the present invention include a binder with high hardness and tensile strength that allows for the creation of drilling tools with increased wear resistance. In particular, one or more implementations include a binder having about 5 to about 50 weight % of nickel, about 35 to about 60 weight % of zinc, and about 0.5 to about 35 weight % of tin. Implementations of the present invention also include drilling tools, such as reamers and drill bits, formed from such binders.
