Tool with etched tip and related method
A workpiece engaging surface that includes a pattern of laser-etched channels and related method of manufacturing is provided. The laser-etched pattern on the surface of the workpiece engaging surface is formed by multiple groupings of closely spaced channels that generate serrated teeth in the surface of the tip. Each grouping of channels is formed by passing a laser over a first location a first number of passes to form a first channel, passing a laser over a second location, spaced apart from the first location by a channel spacing distance, a second number of passes to form a second channel, and passing a laser over a third location, spaced apart from the second location by the channel spacing distance, a third number of passes to form a third channel. In some embodiments the first, second, and third number of passes are the same.
