I have been trying (unsuccesfully) to find some good information on collet adapters. I have access to some free 1/8" solid carbide spiral cut bits and would like to try and use one in my router. My router is a 1/2" router (Hitachi M12v) which comes with a 1/4" adapter. I have searched and found some 1/4" to 1/8" adapters but no 1/2" to 1/8" adapters. I suppose I could put the 1/2-1/4 and 1/4-1/8 adapter in at the same time to transition down in two stages but that just doesn't seem like the best solution. My gut tells me that I might end up with some runout issues as well as possible safety problems. Does anyone have any thoughts?

The right tool for those 1/8" bits is a Rotozip or other brand of spiral saw. A palm router would be fine if it has the right collet bushing. Do not attempt to use them in your Hitachi router. The router is too heavy and you will snap those bits in a NY second. It is not safe to stack collet bushings, they will seperate. Remember that even with their tiny diameter they are still spinning at close to 20,000 RPM.

Hi Holdstock

I have a full set, I got them from MLCS and the 1/2" to 1/8" is in the set BUT like Mike said the 1/8" bits break when you just look at them, I do use the 1/4" to 1/8" one from time to time in my trim router but again you must take real care when using the small bits and I also have a small 1/8" router bit set I got from Grizzly that works great on small boxes, they are about 1/3 the size of a stantard router bits.

But give a it a shot some people have the touch with the big routers .
