Bosch’s popular woodworking router comes with 1/4″ and 1/2″ collets, but what if you want to use different shanked burs and bits? We found that replacement collets were available by 3rd party manufacturers, such as Galaxy Products.
While it may not be wise to hand-hold a full-size router with a 1/8″ collet and bit, this and other collet and bit sizes may come in handy for those using a router in a DIY CNC setup.
Galaxy Products also manufacturers collet size adapters, and replacement collets for a number of other tool styles.
