3M 7100305443 Type 27 Grinding Wheel 4 in 36 Grit

Product Description

The 3M 7100305443 is a Type 27 depressed-center grinding wheel designed for use with right-angle grinders in metal cutting and grinding applications. Built with a precision shaped ceramic abrasive grain and a resinoid bond, this wheel delivers consistent stock removal and long wheel life under sustained load. At 4 inches in diameter and 5/32 inches thick with a 5/8-inch arbor hole, it fits compact angle grinders commonly used in fabrication, maintenance, and industrial metalworking. The reinforced construction supports operation up to 15,300 RPM. It is suited for professional tradespeople working with ferrous and hard metals who need a reliable, aggressive-cutting wheel.

This wheel is intended for cutting and surface grinding applications in fabrication shops, manufacturing facilities, and field maintenance environments. The Type 27 depressed-center profile provides clearance for flush and near-flush grinding on flat stock, weld seams, and structural members. It mounts via an arbor connection standard to right-angle grinders. The 36-grit ceramic abrasive makes it a coarse-cutting option suited for rapid material removal rather than finishing work.

Key Features

• Precision shaped ceramic abrasive grain for aggressive, consistent cutting action
• Type 27 depressed-center profile for flush and near-flush grinding clearance
• Resinoid bond with reinforced construction rated to 15,300 RPM
• 4-inch diameter and 5/8-inch arbor hole fits standard compact right-angle grinders
• 36 grit coarse abrasive suited for rapid stock removal on hard metals
• Lightweight at 0.183 pounds, reducing fatigue during extended use

Compatibility

Designed for use with right-angle grinders accepting a 5/8-inch arbor mount. Intended for cutting and grinding applications on metal stock and weld surfaces.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's guard and flange requirements. Always power down and disconnect the grinder before mounting or removing the wheel. Verify the grinder's rated RPM meets or exceeds the wheel's 15,300 RPM maximum before use. Inspect the wheel for cracks or damage before each use and never exceed the rated maximum RPM.
