This 1/4" to 1/8" collet adaptor shank reducer is the mainstay in the CNC'ers toolbox when 1/8" shank bits are the only ones for the job.
Works for any bit with an 1/8" shank. You will get 2 collets. Rarely will you need more unless you have multiple CNC routers.
Fits all brand routers with 1/4: chuck collet (Makita, Dewalt, B&D, etc)
