Tru-maxx 66253269897 Surface Grinding Wheel 46 Grit

Product Description

The TRU-MAXX 66253269897 is a Type 1 straight surface grinding wheel designed for precision material removal on surface grinders. It measures 10 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole. The wheel is made from aluminum oxide abrasive, rated at 46 grit coarse grade with a J hardness code, placing it in the medium hardness range. Maximum operating speed is 3250 RPM. This wheel is suited for machinists, tool and die shops, and metalworking operations that require consistent stock removal on ferrous metals using horizontal or vertical spindle surface grinders.

This wheel is a standard fit for surface grinding applications involving steel and other ferrous workpieces. The coarse 46 grit rating makes it well suited for aggressive stock removal passes rather than fine finishing work. The non-porous, non-tapered, no-recess Type 1 flat wheel profile is the most common configuration used on reciprocating surface grinder tables in job shops, maintenance facilities, and production grinding cells.
