Tru-maxx 620140 Type 27 Grinding Wheel 7in 24 Grit

Product Description

The TRU-MAXX 620140 is a Type 27 depressed center grinding wheel designed for use with angle grinders in heavy-duty material removal applications. The wheel measures 7 inches in diameter with a 1/4-inch thickness and accepts a 7/8-inch arbor connection. It is manufactured with aluminum oxide abrasive bonded in a resinoid bond matrix, delivering a coarse 24-grit cut suitable for aggressive stock removal on ferrous metals and weld grinding. Rated to a maximum of 8,600 RPM, the wheel meets standard operating speeds for most 7-inch angle grinders. Fabricators, pipefitters, ironworkers, and general maintenance mechanics are the typical end users for this type of abrasive.

This wheel is suited for surface grinding, weld blending, and deburring tasks on structural steel, pipe, and plate in both shop and field environments. The Type 27 raised-hub profile positions the abrasive face at a slight angle relative to the hub, allowing flat surface contact at low grinding angles. It is commonly used in fabrication shops, construction sites, and maintenance facilities where fast, coarse material removal is the primary objective. The 7/8-inch arbor hole fits standard angle grinder spindles in the 7-inch class.

Installation Notes

Mounting and wheel changes should be performed by a qualified operator with the grinder fully powered down and unplugged or lockout-tagged per applicable safety procedures. Inspect the wheel for cracks or damage before mounting and never exceed the marked maximum RPM rating. Ensure the guard is properly installed before operation. Abrasive wheel use is subject to ANSI B7.1 safety standards and applicable workplace safety regulations.
