Overview

The JoPo Grips Reamer is designed to maintain a smooth, precise fit for interchangeable thumb systems by slightly enlarging the inner diameter of installed outer sleeves. Over time, ball coverstock expansion can make outer sleeves tighter, making insertion and removal of inner sleeves more difficult. This tool allows for quick and controlled adjustment without damaging the sleeve or ball.

With the inner sleeve removed, the reamer gently enlarges the outer sleeve’s I.D., restoring the proper fit and ensuring consistent performance. It is compatible with the JoPo Twist system as well as most standard interchangeable outer sleeves.

Replacement Blades Available - The reamer features replaceable blades, allowing pro shops and bowlers to refresh the cutting surface without purchasing a new tool. See the JoPo Grips Reamer Replacement Blade.
