Description
The 4 inch 20 grit red teardrop cupwheel is built for fast, aggressive grinding in tight or confined areas. With a smaller footprint than the 4.5″ model, it delivers powerful results where precision matters — like corners, edges, or vertical surfaces.
Engineered with 20 grit diamond segments and a unique teardrop layout, this wheel removes tough coatings, adhesives, and surface imperfections without leaving horseshoe marks. The medium bond balances aggressive performance with consistent wear, making it ideal for soft to medium concrete prep.
This smaller version is compatible with most 4″ grinders and dust shrouds, including Dust Avenger005 Shroud systems. Despite its compact size, the 4 inch 20 grit red teardrop cupwheel offers high productivity and clean results, especially in areas where larger wheels can’t reach.
