Norton 66260300203 Diamond Grinding Wheel 6in 100 Grit

Product Description

The NORTON 66260300203 is a Type 6A2C electroplated diamond grinding wheel designed for precision tool grinding and cutting applications. Built on a 6-inch diameter platform with a 100-grit fine grade diamond abrasive, this wheel delivers controlled material removal on hard, brittle workpiece materials where conventional abrasives fall short. The electroplated bond holds diamond particles in a single layer across the face, providing consistent cutting action and a long service life between dressings. With a 1-1/4-inch arbor hole and a 1-inch face width, it mounts on standard bench grinders and surface grinders used in tool rooms and maintenance shops.

This wheel is suited for grinding carbide tooling, ceramics, glass, and other hard materials in tool and die shops, maintenance facilities, and production environments. The Type 6A2C cup configuration positions the diamond face at the wheel periphery, making it well matched for off-hand sharpening of carbide-tipped cutting tools, drills, and end mills. It is installed by machinists, tool grinders, and maintenance technicians who require a fine-finish grind on high-hardness substrates.

Key Features

• Electroplated diamond bond retains abrasive particles in a single exposed layer for sharp, consistent cut
• 100-grit fine grade produces smooth surface finishes on carbide and ceramic workpieces
• Type 6A2C cup wheel geometry suits tool face and clearance angle grinding
• 6-inch diameter with 1-1/4-inch arbor hole fits common bench and surface grinder spindles
• 1-inch face width allows efficient contact on tool flanks and rake faces
• 7/16-inch overall thickness keeps wheel mass low for reduced spindle load

Compatibility

Designed as an OEM-style replacement or aftermarket option for Type 6A2C cup wheel positions on bench grinders and surface grinders accepting a 1-1/4-inch arbor and a 6-inch diameter wheel.

Installation Notes

Diamond grinding wheels should be installed by a qualified machinist or tool grinder following the grinder manufacturer's mounting instructions. Always power down and lock out the grinder before changing wheels. Inspect the wheel for visible damage before mounting, and confirm that the machine's rated speed meets or exceeds the wheel's maximum operating speed before starting. Do not overtighten the arbor flange nut; secure it snugly to the manufacturer's guidance without deforming the blotter or flange face.
