Norton 66260288676 Type 11V9 Diamond Grinding Wheel 180 Grit

Product Description

The NORTON 66260288676 is a Type 11V9 diamond grinding wheel designed for precision tool grinding and sharpening applications. Built with a synthetic diamond (SD) abrasive at 180 grit and a Very Fine grade, it is suited for controlled material removal on carbide, ceramic, and hard-alloy tooling. The resinoid bond holds abrasive concentration at 100, delivering consistent cut quality throughout the wheel life. At 5 inches in diameter and 1-3/4 inches overall thickness, this wheel fits standard tool and cutter grinder spindles. It is compatible with both wet and dry operation, giving technicians flexibility based on the material and machine setup. Specification code SD180-R100B99-1/16 identifies the exact formulation for cross-referencing or replacement ordering.

This wheel is used primarily in tool room and production grinding environments where carbide-tipped cutting tools, end mills, drill bits, or similar hard-material workpieces require resharpening or profile grinding. The Type 11V9 cup geometry with a 70-degree face angle is optimized for face and clearance grinding on tool and cutter grinders. The 1/4-inch hole bore fits common spindle arbor configurations found on bench-mounted and automated grinding machines. Both wet coolant and dry-run setups are supported, making it a versatile choice across different shop configurations.

Installation Notes

Installation should be performed by a qualified tool room technician or machinist familiar with grinding wheel mounting procedures. Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B11.9 guidelines. Never exceed the maximum operating speed marked on the wheel or machine guard.
