Tru-maxx 66253255260 Grinding Wheel 10in 36 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253255260 is a Type 1 bench and pedestal grinding wheel designed for aggressive stock removal on ferrous metals and general shop use. It measures 10 inches in diameter, 1-1/2 inches thick, with a 1-inch arbor hole. The wheel uses aluminum oxide abrasive at 36 grit for coarse, fast cutting action. A vitrified bond holds the grain structure together, providing consistent performance and easy dressing. At P hardness (medium hardness rating) with a grain structure of 5 and semi-friable abrasive, this wheel self-sharpens during use and maintains a free-cutting action. The maximum rated speed is 3250 RPM. It weighs 6.32 pounds and ships as a single unit.

This grinding wheel suits bench grinders and pedestal grinders found in machine shops, fabrication facilities, maintenance departments, and tool rooms. The 36 grit coarse grade makes it appropriate for rapid material removal, deburring, shaping, and rough sharpening of tools and workpieces. The gray aluminum oxide composition handles general-purpose grinding on carbon steel, alloy steel, and similar ferrous materials. No bushing is included, so verify arbor compatibility before installation.

Compatibility

Designed as a replacement or spare for bench grinders and pedestal grinders accepting a 10-inch diameter, 1-inch arbor hole, Type 1 straight wheel. Verify that the grinder spindle speed does not exceed 3250 RPM before mounting.

Installation Notes

Installation should be performed by a qualified technician following ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels. 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 force a wheel onto a spindle or alter the arbor hole. Use proper flanges and a blotter on each side of the wheel as required by the grinder manufacturer.
