Norton 66253370848 Type 27 Grinding Wheel 9in Ceramic

Product Description

The NORTON 66253370848 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal and fabricated surfaces. Built with ceramic alumina abrasive and a resinoid bond, this wheel delivers a coarse cut suited for weld grinding, surface prep, and stock removal tasks. The 9-inch diameter and 1/4-inch thickness make it a standard choice for large-angle grinders used in heavy fabrication and structural work. At 1.68 pounds, it offers a solid feel without excessive added weight on the tool. Licensed tradespeople and fabricators working in industrial, commercial, and field environments will find this wheel well-suited for sustained grinding operations.

This wheel fits standard large-angle grinders with a 7/8-inch arbor hole. It is used in metal fabrication shops, structural steel work, pipe fitting, and similar trades where fast, coarse grinding is required. The Type 27 profile — a flat center with a depressed hub — positions the grinding surface at an angle to the workpiece, giving the operator clearance for flush and edge grinding without the tool body contacting the material. It is appropriate for both shop and on-site applications.

Key Features

• Ceramic alumina abrasive provides aggressive, coarse-grade stock removal
• Resinoid bond construction supports high-speed grinder use
• Type 27 depressed center profile allows flush and edge grinding clearance
• 7/8-inch arbor hole fits standard large-angle grinder spindles
• 9-inch diameter suits high-material-removal applications on large surfaces
• Non-flexible wheel construction maintains consistent geometry under load

Compatibility

Designed as an OEM-style replacement or direct-use grinding wheel for large-angle grinders accepting a 9-inch diameter, 7/8-inch arbor Type 27 wheel.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheel use. Always power down and disconnect the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting — never use a damaged wheel. Ensure the grinder guard is in place and the spindle speed rating matches or exceeds the wheel's rated maximum RPM before operating.
