The TRU-MAXX RESIN-21 is a Type 11V9 resinoid-bond diamond grinding wheel engineered for precision tool grinding and surface finishing at 150 grit (Very Fine grade). The wheel measures 3.75 inches in diameter and 1.5 inches overall thickness with a 1.25-inch arbor hole. It carries a synthetic diamond (SD) abrasive at 100 concentration, making it well-suited for grinding carbide, ceramic, glass, and other hard or brittle materials. The resinoid bond provides controlled cut action and good surface finish at this grit level. The wheel supports both wet and dry operation, giving the installer flexibility based on the application and available coolant setup.
This wheel is intended for use on tool and cutter grinders in machine shop, toolroom, and industrial maintenance environments. The Type 11V9 flared-cup profile with a 70-degree face angle is a standard configuration for sharpening carbide-tipped cutting tools, end mills, and similar tooling. It is sold individually (package quantity of 1) and is appropriate for professional machinists, tool grinders, and industrial maintenance technicians working with hard-material tooling.
Designed as an OEM-style replacement or aftermarket option for Type 11V9 diamond grinding wheel applications on standard tool and cutter grinders accepting a 1.25-inch arbor hole and a 3.75-inch diameter wheel.
Installation should be performed by a qualified machinist or tool grinder technician familiar with abrasive wheel mounting procedures. Always power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before mounting and never exceed the rated operating speed marked on the wheel or its packaging. When wet operation is selected, verify that coolant lines are clear and flowing before beginning the grind cycle.
