BIHUI B-Speedy Diamond Blade — Fast Cuts, Clean Edges, Less Dust When you're cutting dense porcelain and hard ceramic all day, you need a blade that's quick without tearing up the edge. The BIHUI B-Speedy is built for exactly that. Its full-height turbo mesh diamond rim bites fast and clears material efficiently, while the ultra-thin 1.2 mm profile means a narrower kerf, less dust in the air, and less drag on your grinder. A special hardened-steel body keeps the blade flat and stable at speed, and the self-cooling design helps it shrug off heat on long, continuous cuts — so you get clean, chip-reduced edges on porcelain, ceramic, hard tile, and tile slabs, wet or dry. The B-Speedy comes in more than one size so you can match the blade to the tool and the task. The 4.5" (115 mm) and 5" (125 mm) versions ride a 7/8" (22.23 mm) arbor with a 55 mm reinforced double flange for stability in a standard angle grinder — ideal for straight cuts, plunge cuts, and trimming larger tile. The compact 3" version is sized specifically for the BIHUI Mini Cordless Angle Grinder 3" Diameter (SKU AGMN3M). Paired with that cordless mini grinder, the 3" B-Speedy becomes a nimble detail tool — perfect for cutting outlet openings, trimming inside niches, notching around pipes and valves, and dialing in close-quarters cuts where a full-size grinder simply won't fit. Why Tile Pros Choose It Cuts faster: Turbo mesh rim and thin kerf move through hard porcelain quicker than conventional blades Cleaner edges: Minimal chipping means less touch-up and fewer wasted tiles Less dust: The ultra-thin 1.2 mm blade throws off noticeably less dust Wet or dry: One blade covers both setups — saw tray or freehand grinder Built to last: Hardened special-steel body and reinforced core stay true under daily use Stays cooler: Self-cooling design resists heat glazing on long cuts Right size for the job: 3" for the cordless mini grinder, 4.5" and 5" for standard grinders Won't quit before you do: The kind of blade that lives in the truck for months, not days Pro tip: Running the 3" B-Speedy on the BIHUI Mini Cordless Angle Grinder? Let the blade do the work — light, steady passes give you the cleanest edge and the longest blade life, and a quick pass on a dressing stone will wake the diamonds back up if the cut ever starts to slow.
