Dewalt DW8831 Zirconia Grinding Wheel 9x1/8x5/8-11

Product Description

The DEWALT DW8831 is a zirconia bonded abrasive grinding wheel designed for heavy-duty material removal on angle grinders. The 9-inch diameter wheel measures 9 inches x 1/8 inches in diameter and thickness, with a 5/8 inches-11 threaded arbor mount for secure attachment to compatible angle grinders. Zirconia alumina abrasive grain delivers aggressive stock removal and extended wheel life compared to standard aluminum oxide wheels. This wheel is sold individually and weighs 1.02 pounds. It is suited for trades professionals who need consistent, controlled grinding performance on the job site or in the shop.

The DW8831 is used for grinding and surface preparation on ferrous metals including structural steel, weld seams, and fabricated components. The 1/8-inch thickness makes it appropriate for general grinding tasks rather than cutting, providing lateral stability during aggressive passes. Typical applications include weld grinding, deburring, and stock removal in fabrication, mechanical, and maintenance settings. This wheel is commonly used by pipefitters, ironworkers, millwrights, and general maintenance technicians working with carbon steel and similar ferrous materials.

Key Features

• Zirconia alumina abrasive grain for aggressive material removal and extended service life
• 9-inch diameter provides a large grinding surface for faster coverage on flat and curved workpieces
• 1/8-inch wheel thickness delivers lateral stability for general-purpose grinding passes
• 5/8 inches-11 threaded arbor hub fits standard large angle grinder spindles
• Bonded abrasive construction for consistent grain exposure throughout wheel life

Compatibility

Designed as an OEM-style replacement grinding wheel for large 9-inch angle grinders with a 5/8 inches-11 threaded spindle.

Installation Notes

Grinding wheel installation and replacement should be performed by a qualified technician following the angle grinder manufacturer's instructions and applicable ANSI B7.1 safety standards. Always power down and unplug or de-energize the grinder before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and never operate above the maximum RPM marked on the wheel. Wear appropriate PPE including a face shield and gloves during installation and operation.
