Tru-maxx 66253292493 Surface Grinding Wheel 80 Grit 10 in

Product Description

The TRU-MAXX 66253292493 is a Type 1 straight surface grinding wheel designed for bench and surface grinders in metalworking and fabrication environments. It measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond and carries a medium grade with an 80 grit and K hardness code. Rated to a maximum of 3,250 RPM, it is suited for precision surface grinding of ferrous metals. Machinists, tool and die makers, and general metalworking shops are the primary users of this wheel.

This wheel fits standard surface grinders and bench grinders equipped with a 3-inch arbor and accommodating a 10-inch diameter wheel. The Type 1 straight configuration makes it appropriate for flat surface grinding operations on steel and other ferrous workpieces. The 80 grit and medium grade combination balances stock removal with surface finish quality, making it a practical choice for general-purpose precision grinding work in job shops and production environments.

Key Features

• 80 grit, K hardness code, medium grade for balanced material removal and surface finish
• Type 1 straight wheel profile for flat surface grinding applications
• 3-inch arbor hole fits standard surface and bench grinder spindles
• Maximum rated speed of 3,250 RPM
• Semi-friable grain with grain structure 5 for self-sharpening behavior under moderate load
• Non-porous, no recess, non-tapered construction for straightforward mounting

Compatibility

Designed as a direct-fit replacement or standard-use grinding wheel for surface grinders and bench grinders equipped with a 3-inch arbor and a 10-inch wheel capacity.

Installation Notes

Grinding wheel installation and dressing should be performed by a qualified machinist or shop 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. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum rated spindle speed of 3,250 RPM. Use the correct flanges and blotters for proper clamping, and stand clear during the initial run-up period after mounting.
