Norton 69014192223 Type 12A2 Diamond Grinding Wheel 180 Grit

Product Description

The NORTON 69014192223 is a Type 12A2 superabrasive grinding wheel designed for precision grinding of hard and brittle materials. It features a synthetic diamond (SD) abrasive at 180 grit, placing it in the very fine grade range. The resinoid bond supports both wet and dry operation, making it adaptable to bench grinder and surface grinder setups. At 4 inches in diameter with a 1/4-inch face width and 25-degree face angle, this wheel delivers controlled material removal on carbide tooling, ceramics, and hard steels. Licensed HVAC, machine tool, and maintenance trade professionals specify this wheel for tool and cutter grinding applications.

This wheel is suited for tool room and production grinding environments where a fine finish and dimensional accuracy are required. The Type 12A2 geometry is a standard profile for tool and cutter grinders used in resharpening carbide-tipped cutting tools, ceramic components, and similar hard substrates. Its 1-1/4-inch bore fits common spindle arbors found on bench grinders and dedicated tool grinders. Both wet and dry operation are supported, though wet grinding is preferred for heat-sensitive materials.

Installation Notes

Installation should be performed by a qualified tool room technician or machinist familiar with superabrasive wheel mounting procedures. Power down and lock out the grinder before mounting. Inspect the wheel for cracks or chips before each use and never exceed the rated RPM marked on the wheel. Follow ANSI B7.1 safety standards for abrasive wheel use and mounting.
