Abstract
A method for coloring tool bits includes cutting a beam having a hexagonal cross section into a number of segments. The segments are electroplated for forming an outer layer on the segments. The segments each have one or two of the ends machined to form a tool bit end for engaging with fasteners. The segments are then dyed for allowing color material to be attached onto the tool bit end and for coloring the tool bit end. The electroplated outer layer may prevent the color material from attaching onto the outer peripheral portion of the segments.
