E-11 1/8” Shank for Type R & S Quick Change Disc Pad Holders

The Pro-Graad E-11 is a precision-machined shank adapter designed to bridge the gap between your existing Quick Change disc pad holders and smaller 1/8" rotary tools. If you have a collection of Type R or Type S Quick Change holders and need to run them on a rotary tool with a 1/8" collet, the E-11 eliminates the need to buy duplicate tooling. The adapter features a 1/4-20 male thread that engages directly with the center-threaded receptacle found on standard Roll Lock and Quick Change pad holders. The opposite end is a true 1/8" shank that chucks cleanly into any 1/8" collet or keyless chuck. The result is a solid, secure connection that translates rotary power to your disc pad holder with minimal wobble or runout. Applications span the full range of surface prep and finishing work: rust and paint removal with surface conditioning discs, weld blending, edge deburring, gasket surface prep, and precision detail finishing in tight access areas where a full-size grinder won't fit. The smaller tool profile made possible by the 1/8" shank connection lets you work in corners, channels, and confined geometries that larger tooling can't reach. Built to the same dimensional standards as the Quick Change system itself, the E-11 threads in securely without slop or play. If you run Type R or Type S discs across multiple tool platforms, this adapter keeps your consumable inventory unified and your tooling costs down. One adapter per pack.
