Norton 66252809608 Type 11 Grinding Wheel 6 in 16 Grit

Product Description

The NORTON 66252809608 is a Type 11 snagging grinding wheel engineered for aggressive material removal on metal and masonry surfaces. Built with a dual-abrasive blend of aluminum oxide and silicon carbide, this wheel carries a 16 grit rating for very coarse stock removal and a Q hardness code indicating a hard resinoid bond. The wheel measures 6 inches in diameter, 2 inches in overall thickness, and runs at a maximum of 6,000 RPM. Sold under the Gemini trade name, it is designed for foundry snagging, weld dressing, and heavy flash removal tasks handled by metalworking and fabrication professionals.

This wheel fits Type 11 flange-mounted angle grinders and snagging grinders used in industrial and manufacturing environments. The 5/8-11 hub thread and 4-3/4 inch hub diameter match standard arbor configurations common to bench and pedestal-style snagging machines. Typical applications include casting cleanup, weld bead removal, and scale grinding on ferrous and non-ferrous workpieces. The hard bond sustains wheel life under continuous heavy-pressure operation, making it well suited for production-floor use rather than light occasional grinding.

Key Features

• Dual abrasive blend: aluminum oxide and silicon carbide for aggressive cut on varied materials
• 16 grit, very coarse — maximizes material removal rate per pass
• Q hardness (hard resinoid bond) sustains wheel integrity under high-pressure snagging loads
• Type 11 cup geometry fits standard flange arbor snagging grinder setups
• 5/8-11 hub thread for secure, vibration-resistant mounting
• 6,000 max RPM rating clearly marked for operator safety compliance

Compatibility

Designed for use with Type 11 snagging grinders accepting a 5/8-11 hub thread and a 4-3/4 inch hub diameter, as specified by the manufacturer for this wheel geometry.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 standards. Always power down and disconnect the grinder before mounting or removing a wheel, and inspect the wheel for cracks or chips before each use. Never exceed the 6,000 max RPM marked on the wheel. Use proper guarding and personal protective equipment including face shield and hearing protection during operation.
