Weiler 59931 Grinding Disc 4.5 Inches 24 Grit Zirconia

Product Description

The WEILER 59931 is a 4.5-inch recess flat depressed center grinding disc engineered for aggressive material removal on steel and stainless steel. It combines self-sharpening zirconia alumina and ceramic alumina grains to deliver a fast, consistent cut rate throughout the life of the disc. The superior grain blend minimizes shedding, which extends disc life and promotes cooler grinding temperatures. This disc is suited for grinding, blending, and finishing applications and is installed by metal fabricators, welders, and ironworkers using a 5/8-11 UNC threaded angle grinder.

This disc is designed for use on steel and stainless steel in both fabrication shop and field environments. At 4.5 inches in diameter with a 24Z grit, it is well matched to heavy stock removal and weld blending where a fast cut rate and long disc life are priorities. The cool-grinding characteristic makes it appropriate for heat-sensitive stainless steel work where discoloration and material distortion must be minimized.

Key Features

• Blend of self-sharpening zirconia alumina and ceramic alumina grains for fast, consistent cut rate
• Superior disc design minimizes grain shedding to extend service life
• Cool grinding action reduces heat buildup on steel and stainless steel
• 24Z grit rating suited for aggressive grinding and weld blending
• 5/8-11 UNC arbor fits standard angle grinders
• Applicable for grinding, blending, and finishing operations

Compatibility

Designed as an OEM-style replacement or direct-fit disc for angle grinders with a 5/8-11 UNC spindle thread accepting 4.5-inch depressed center grinding discs.

Installation Notes

Installation is performed by metal fabricators, welders, or qualified tradespeople using a compatible angle grinder. Before mounting the disc, ensure the grinder is fully powered down and the power source is disconnected. Inspect the disc for cracks or damage before each use and confirm the grinder RPM rating meets or exceeds the disc RPM rating. Always use the appropriate guard and personal protective equipment per ANSI B7.1 and applicable OSHA standards.
