tim...between the standard gears, the .25X set, the .50X set and the 2X set just about all pitches anyone would want are covered( a total of 28...with 3 duplications)...we even played with mixing gears from different sets, but the difference in pitches is negligible...again, i'll assume most of the legacy guys design around the router bit...whereas we design first, and then find the bit that will work with our design, whether we order a custom bit or make it ourselves...joe
