3M 7100305443 Cut and Grind Wheel 4 in 36+ Grit

Product Description

The 3M 7100305443 is a Cubitrona 3 Cut and Grind Wheel engineered for trade professionals who need a single abrasive tool capable of both cutting and grinding. Built with 3M Re-Engineered Precision Shaped Ceramic Grain, the wheel continuously fractures during use to expose sharp cutting points, which keeps the wheel running cool and wearing evenly. Rated at 36 plus grit, it delivers aggressive material removal on stainless steel and mild steel. The rigid, resin-bonded, reinforced construction holds up through gouging, cutting, and surface grinding without requiring excessive operator pressure.

This wheel is suited for fabrication shops, maintenance facilities, and field service environments where both cutting and grinding operations are performed on ferrous metals. It is appropriate for stainless steel work where heat management matters, as the self-fracturing grain reduces heat buildup at the contact surface. The 4-inch diameter fits standard 4-inch angle grinders common in HVAC, plumbing, and general mechanical trades. Sold in a minimum quantity of 2 per order.

Installation Notes

Wheel installation and replacement should be performed by a qualified technician familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always power down and disconnect the grinder before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and never exceed the maximum RPM rating marked on the wheel. Use appropriate eye protection, hearing protection, and gloves during operation.
