Weiler 56464 Type 27 Grinding Wheel 4.5in Aluminum Oxide 24G

Product Description

The WEILER 56464 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with aluminum oxide abrasive and a coarse 24 grit rating, it cuts quickly through welds, castings, and rough stock. The resinoid bond holds the abrasive grain firmly under load, while the R hardness rating balances wheel life against cut rate. At 4.5 inches in diameter and 0.25 inches thick, this wheel mounts on a standard 7/8 inch arbor and fits most right-angle grinders in the 4.5 inch class. It is installed and used by metal fabricators, ironworkers, pipefitters, and maintenance machinists.

This grinding wheel is suited for heavy stock removal, weld grinding, and surface conditioning on ferrous metals. The Type 27 depressed center profile keeps the grinding face slightly raised from the workpiece, giving the operator better clearance and control during flat or beveled surface work. It is a common choice on jobsites and in fabrication shops where high material removal rate on mild steel, stainless, or cast iron is the priority. The coarse grit and resinoid bond make it better suited to rough grinding than finishing passes.

Key Features

• Type 27 depressed center profile for improved clearance and flat-surface grinding control
• Aluminum oxide abrasive with 24 grit coarse grade for fast, aggressive stock removal
• Resinoid bond construction maintains grain integrity under continuous load
• R hardness code balances wheel longevity with cutting efficiency
• 7/8 inch arbor hole fits standard right-angle grinders in the 4.5 inch class
• Lightweight at 0.2 pounds, minimizing added tool weight during extended use

Compatibility

Designed as a direct-fit replacement for 4.5 inch Type 27 depressed center grinding wheels with a 7/8 inch arbor hole, compatible with right-angle grinders accepting that wheel diameter and arbor size.

Installation Notes

Grinding wheels must be installed and changed by trained personnel following ANSI B7.1 safety standards for abrasive wheel use. Inspect the wheel for cracks or chips before mounting and never operate above the rated RPM marked on the wheel. Power down and disconnect the grinder from its power source before changing wheels. Always use the appropriate guard for Type 27 wheels as required by OSHA and tool manufacturer guidelines.
