Tru-maxx 66253255171 Bench Pedestal Grinding Wheel 10in

Product Description

The TRU-MAXX 66253255171 is a Type 1 bench and pedestal grinding wheel designed for use on standard bench grinders and pedestal grinders in machine shops, maintenance facilities, and fabrication environments. The wheel measures 10 inches in diameter, 1 inch thick, with a 1-1/4 inch arbor hole and is constructed from aluminum oxide abrasive bonded in a vitrified bond matrix. At a 46 grit, coarse grade rating, it is suited for aggressive stock removal on ferrous metals. The wheel carries a maximum operating speed of 3250 RPM and weighs 7.86 pounds. It is typically mounted and dressed by machinists, tool and die workers, and maintenance technicians performing edge work, deburring, or tool sharpening.

This grinding wheel fits bench grinder and pedestal grinder applications where a coarse, fast-cutting wheel is required. The aluminum oxide abrasive and vitrified bond make it appropriate for grinding carbon steel, alloy steel, and similar ferrous workpieces. The Gray wheel color and semi-friable grain structure allow the wheel to self-dress during use, maintaining a reasonably open cutting face. No reducer bushings are included, so the arbor bore must match the spindle or a separately sourced bushing set must be used. Typical use cases include tool sharpening, surface conditioning, and rough stock removal in shop maintenance settings.

Key Features

• 10 inch diameter Type 1 flat wheel profile for standard bench and pedestal grinder spindles
• 46 grit coarse grade for aggressive material removal on ferrous metals
• Aluminum oxide abrasive with vitrified bond for durability and consistent cut rate
• Semi-friable grain structure supports self-dressing action during use
• Wheel hardness grade P with grain structure 5 for a medium-hard, controlled wheel wear rate
• Rated to 3250 RPM maximum operating speed

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for bench grinders and pedestal grinders accepting a 10 inch diameter, 1 inch wide, Type 1 wheel with a 1-1/4 inch arbor bore. No bushing is included; confirm spindle bore diameter before installation.

Installation Notes

Grinding wheel installation should be performed by a qualified technician following ANSI B11.9 and applicable OSHA standards for abrasive wheel machinery. Always power down and lock out the grinder before mounting or removing a wheel. Perform a ring test by tapping the wheel lightly with a non-metallic mallet and listening for a clear tone before mounting; a dull thud may indicate a cracked wheel that must not be used. Do not exceed the 3250 RPM maximum speed rating stamped on the wheel, and always install the correct flanges and blotters as specified by the grinder manufacturer.
