Tru-maxx 66253269715 Grinding Wheel 7in 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253269715 is a Type 1 bench and pedestal grinding wheel designed for material removal, tool sharpening, and edge dressing on stationary grinders. It measures 7 inches in diameter, 3/4 inches thick, with a 1-inch arbor hole. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond, rated at a medium grade and grit 60. With a grain structure of 6 and semi-friable abrasive, it cuts aggressively while resisting loading. Maximum operating speed is 3600 RPM. Weighing 3.79 pounds, it fits standard bench and pedestal grinder setups commonly found in machine shops, maintenance facilities, and fabrication environments.

This wheel is suited for general-purpose grinding of ferrous metals including steel and cast iron. It is used in maintenance, repair, and operations settings where tool reconditioning, deburring, and surface shaping are routine tasks. The 60-grit medium grade makes it appropriate for stock removal where a moderately smooth finish is acceptable. Licensed machinists, maintenance technicians, and metalworking tradespeople are the primary installers and operators. No bushing is included, so confirm arbor bore compatibility with the host machine before mounting.

Key Features

• 60 grit, medium grade aluminum oxide abrasive for general-purpose ferrous metal grinding
• Vitrified bond with grain structure 6 provides consistent stock removal and wheel integrity
• Semi-friable abrasive resists glazing and maintains cutting action over the wheel life
• Type 1 straight wheel geometry fits standard bench and pedestal grinder flanges
• 3600 RPM maximum speed rating compatible with common 7-inch bench grinder spindles
• Non-porous construction; wheel color gray; specification code 27A60O6V13

Compatibility

Designed as an OEM-style replacement or standard service wheel for bench and pedestal grinders accepting a 7-inch diameter, 3/4-inch wide, Type 1 straight wheel with a 1-inch arbor bore. No bushing is included; reducers must be sourced separately if the machine spindle bore differs.

Installation Notes

Always power down and lockout the grinder before removing or mounting a grinding wheel. Inspect the wheel visually and perform a ring test before installation to check for cracks or damage. Mount using properly sized flanges that cover at least one-third of the wheel diameter, and never exceed the 3600 RPM maximum speed rating marked on the wheel. Wheel dressing with a diamond dresser or star dresser is recommended after mounting to true the face and expose fresh abrasive.
