Ultimate Interchangeable Thumb Empty Inner Sleeve 1 1/4″

“THE” Ultimate Thumb – this unique two-piece system is simple, durable and reliable! For Pro Shops, our patented auto-depth flange eliminates any guess work or need for a stopper on your drill bit. The inner contains a stopper at the bottom which will leave the thumb insert about an 1/8?-1/4? above the auto-depth feature, allowing you to use a plug-cutter for simple removal. The four-tab inner allows for easy, quick removal and insertion from ball-to-ball which will minimize time when needing to use multiple balls on your pair. This system doesn’t attach at the bottom therefore, any tension is evenly disbursed which nearly eliminates any possibility of breakage. Secure locking of “THE” Ultimate Thumb will be felt and heard, providing the confidence that your thumb won’t move up and down!
