Tru-maxx 66253269674 Surface Grinding Wheel 46 Grit 10 in

Product Description

The TRU-MAXX 66253269674 is a Type 1 surface grinding wheel designed for flat and surface grinding operations on ferrous metals and tool steels. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal and a controlled finish. The wheel measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole. At 46 grit with an H hardness rating, it falls in the coarse-grade range, making it well suited for aggressive material removal where surface finish is secondary to throughput. This wheel is rated to a maximum of 2,480 RPM and weighs 5 pounds.

This grinding wheel is used in surface grinding machines common to machine shops, tool rooms, and maintenance facilities. The Type 1 straight-wheel profile mounts on horizontal-spindle surface grinders. The coarse 46-grit specification makes it a practical choice for rapid stock removal on steel workpieces, weld dressing, and tool reconditioning. The vitrified bond resists heat buildup and allows the wheel to break down at a controlled rate, keeping cutting action consistent through the wheel life. It is a non-recessed wheel with no porous structure, suited for standard wet or dry surface grinding setups.

Key Features

• Type 1 straight-wheel profile for horizontal-spindle surface grinders
• Aluminum oxide abrasive with semi-friable grain structure for self-sharpening action
• Vitrified bond provides rigidity and resistance to oils, water, and common grinding fluids
• 46 grit coarse grade for aggressive stock removal
• H hardness (soft rating) allows the wheel to release dull grains, reducing glazing
• Rated to 2,480 RPM maximum operating speed

Compatibility

Designed as an OEM-style replacement or standard consumable for horizontal-spindle surface grinders accepting a Type 1 wheel with a 3-inch arbor hole, 10-inch diameter, and 1-inch face width.

Installation Notes

Surface grinding wheels must be installed by a qualified machinist or grinding machine operator following ANSI B11.9 and applicable OSHA grinding safety standards. Always perform a ring test before mounting to check for cracks, and confirm the machine spindle speed does not exceed the 2,480 RPM maximum rating stamped on the wheel. Mount with proper flanges and blotters and guard in place before powering on. Never exceed the rated speed or use a wheel that shows visible damage.
