Tru-maxx 66253255251 Grinding Wheel 10in 80 Grit

Product Description

The TRU-MAXX 66253255251 is a Type 1 bench and pedestal grinding wheel designed for material removal and tool sharpening on standard bench grinders and pedestal grinders. It measures 10 inches in diameter, 1 inch thick, with a 1-1/4 inch arbor hole. The abrasive material is aluminum oxide with an 80-grit medium grade, making it well suited for general-purpose ferrous metal grinding. The vitrified bond provides consistent grain exposure and thermal stability during extended use. Rated at a maximum of 3250 RPM, this wheel is appropriate for fixed-speed bench and pedestal grinder applications in shops, maintenance facilities, and trade environments. No bushing is included.

This grinding wheel is used in metalworking, maintenance, and fabrication settings where controlled stock removal on steel, iron, and similar ferrous materials is required. It is commonly installed on bench grinders and pedestal grinders in HVAC shops, plumbing and pipefitting facilities, electrical contractors shops, and general industrial maintenance operations. The 80-grit medium grade handles tool dressing, edge shaping, and weld cleanup without excessive heat buildup at the workpiece.

Compatibility

Designed as an OEM-style replacement or standard fitment for bench grinders and pedestal grinders accepting a 10 inch diameter, 1 inch wide, Type 1 straight wheel with a 1-1/4 inch arbor hole. Specification code 27A80P5V13 identifies this wheel for cross-reference purposes.

Installation Notes

Grinding wheel installation should be performed by a qualified technician following ANSI B11.9 and applicable OSHA standards for abrasive wheel machinery. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting and perform a ring test as specified by the wheel manufacturer. Never exceed the maximum RPM stamped on the wheel, and ensure flanges and the arbor bore are clean and properly seated before operation.
