Description
This 1/2″ to 1/4″ collet adaptor shank reducer is the mainstay in the CNC’ers toolbox when 1/4″ shank bits are the only ones for the job….and all you have is a 1/2″ chuck on your router.
Works for any bit with a 1/4″ shank. Rarely will you need more than 1 unless you have multiple CNC routers.
Fits all brand routers and machining centers with 1/2″ spindle chuck collets.
