A device and method are provided for reducing a length of an annular core on which a roll is mounted. If the core extends beyond the end of the roll, the roll is unstable when it is stacked. This device and method will trim the length of the core extending beyond the end of the roll to provide a flat face across the entire end of the roll. A stable stacking arrangement will therefore be ensured. The router includes a collar, a router bit and a transparent disk or plate mounted thereon. The router bit will chip away the portion of the core which extends beyond the end of the roll. A vacuum can be operatively attached to the router in order to remove chips formed by the router bit. The collar on the router will keep the bit spaced from the roll to prevent damage to the roll. This collar and the transparent disk or plate will also aid in guiding the router.
