Tru-maxx 66253269900 Surface Grinding Wheel 8in 60 Grit

Product Description

The TRU-MAXX 66253269900 is a Type 1 surface grinding wheel designed for bench and pedestal grinder applications. It measures 8 inches in diameter and 1/2 inch thick, with a 1-1/4 inch arbor hole. The wheel is constructed from aluminum oxide abrasive, rated at 60 grit with a G hardness code, placing it in the soft hardness range. A coarse cutting action makes it well suited for aggressive stock removal on ferrous metals. Maximum operating speed is 3600 RPM. Weight is 1.78 pounds. Machinists, tool and die workers, and maintenance technicians are the typical end users.

This wheel fits standard 8-inch bench grinders and pedestal grinders used in machine shops, maintenance facilities, and fabrication environments. The porous, ruby-colored aluminum oxide bond is a common choice for general-purpose grinding of carbon steel, alloy steel, and similar ferrous workpieces. The Type 1 flat-wheel profile suits straight surface grinding and tool sharpening setups. No recess is present on either face.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or maintenance technician following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum RPM of 3600. Power down and lock out the grinder before changing wheels. Use the correct flanges and tighten the arbor nut only to snug, avoiding overtightening that can crack the wheel.
