Tru-maxx T1-7W33946-T Surface Grinding Wheel 100 Grit

Product Description

The TRU-MAXX T1-7W33946-T is a Type 1 surface grinding wheel designed for precision stock removal and surface finishing on ferrous and hard materials. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and good form retention under steady grinding pressure. The wheel measures 7 inches in diameter, 1-1/4 inches bore, and 1/4 inch thick. At 100 grit with an L hardness rating, it falls in the fine-grade range — suited for finishing passes where surface finish quality matters as much as material removal rate. Rated to 3,600 RPM maximum. Weight is 1 pound.

This wheel is intended for use on surface grinders in job shop, maintenance, and manufacturing environments. The no-recess flat face profile is standard for Type 1 straight wheel applications on horizontal-spindle surface grinders. Machinists, tool and die makers, and maintenance technicians use this wheel for finishing flat surfaces on steel, cast iron, and similar ferrous workpieces. It is sold individually.

Key Features

• Aluminum oxide abrasive — well-suited for grinding steel and ferrous metals
• Vitrified bond provides good form retention and consistent cut throughout wheel life
• 100 grit fine grade for finishing passes and tight surface finish requirements
• L hardness rating balances wheel wear against workpiece surface finish
• No-recess flat face profile standard for horizontal-spindle surface grinders
• 3,600 RPM maximum speed rating

Compatibility

Designed as an OEM-style replacement or direct-use wheel for horizontal-spindle surface grinders accepting a 7-inch diameter, 1-1/4-inch bore, 1/4-inch thick Type 1 straight wheel.

Installation Notes

Surface grinding wheels must be installed and dressed by a qualified machinist or grinding equipment operator following ANSI B11.22 and OSHA 29 CFR 1910.215 guarding requirements. Always perform a ring test before mounting and verify the spindle RPM rating does not exceed the wheel maximum of 3,600 RPM. Mount the wheel using proper flanges and blotters; never exceed recommended flange diameter ratios. Guard the wheel fully before powering on the machine.
