5" HDII – One Wheel. All Materials. No Swapping.
The 5" HDII (Handi Disc II) is built for tradesmen who don’t have time for wheel changes, flying debris, or tools that can’t keep up. With 46-grit diamond coating on both the face and edge, this disc cuts, grinds, shapes, and bevels everything from steel to concrete without missing a beat.
Skip the fiberglass wheels that wear down fast and blow apart under pressure. The HDII’s solid steel core runs cooler, lasts longer, and keeps you in control—whether you’re grinding welds, cutting rebar, shaping tile, or cleaning up masonry.
