They sell adapters to use Roto Zip bits in 1/4" router collets here, so they may also offer them elsewhere. I use them with the adapter in my smaller routers.
Without a bearing on the tip they require a lubricant or you will burn the edge of your template. This is also helpful if using a router bit with a brass guide tip. I brush a thin layer of Vaseline on the template edge where the guide tip will rub. I also do this when using the solid carbide laminate trimmer bits to trim laminate, basically any bit that has a smooth guide but no bearing, or a bearing that isn't spinning all that free. It can make a mess if you use too much, but it does eliminate the the burning.
