Blastrac Tornado Cup 50/60 Grit
Blastrac Tornado Cup 50/60 Grit is a high-performance diamond cup wheel engineered for concrete polishing, scratch refinement, and edge smoothing on 5-inch angle grinders and surface preparation equipment. With 18 curved “tornado” diamond segments along its outer perimeter, this wheel creates a continuous cutting action that shears down surface imperfections and transitions slabs smoothly into finer polishing grits. The medium-fine 50/60 diamond grit eliminates heavy scratch marks left by aggressive desurfacing tools without gouging or chipping the mineral face.
Built on a lightweight 1.25 lb steel dish featuring large perimeter cooling cutouts, the Tornado cup wheel facilitates rapid dust evacuation and constant airflow across the contact zone to prevent heat buildup and premature segment glazing. Its dish-style design with a center bore mounts securely to standard 5-inch grinder spindles using standard flange nuts. Suitable for both wet and dry processing, this 18-segment wheel delivers balanced rotation, minimal operator vibration, and a clean, consistent scratch profile across concrete, terrazzo, and masonry substrates.
Main Features
- 18 Curved Tornado Segments: Specially angled segment geometry delivers smooth cutting and efficient material evacuation.
- 50/60 Medium-Fine Diamond Grit: Refines coarse tooling scratches and prepares concrete, terrazzo, and masonry for high-grit polishing stages.
- High-Flow Cooling Vents: Large cutouts across the steel body dissipate friction heat and optimize vacuum suction through dust shrouds.
- Balanced 1.25 lb Lightweight Body: Minimizes machine vibration and operator fatigue during detailed edging and surface work.
- Versatile Wet & Dry Operation: Delivers dependable performance connected to dry dust extractors or underwater lubrication.
