Norton 66254461185 Flap Disc 7 in 60 Grit Zirconia Type 29

Product Description

The NORTON 66254461185 is a 7-inch Type 29 flap disc designed for aggressive grinding and blending on metal surfaces. It uses zirconia alumina abrasive on a cloth backing, which delivers a consistent cut rate and extended disc life compared to standard aluminum oxide options. The angled Type 29 profile increases surface contact during use, making it well-suited for work on flat stock and weld seams. Rated to 8,600 RPM, this medium-grade 60-grit disc is installed on angle grinders fitted with a 7/8-inch arbor. Fabricators, pipefitters, and metalworkers are the primary users of this type of disc.

This flap disc is used in metal fabrication shops, structural steel work, and field welding applications where weld dressing, surface blending, and material removal are performed in a single pass. The 60-grit medium grade removes material efficiently while leaving a finish suitable for inspection or further finishing steps. It is appropriate for ferrous metals including mild steel and stainless steel in both shop and jobsite environments.

Key Features

• Type 29 angled flap configuration for increased surface contact and aggressive stock removal
• Zirconia alumina abrasive for extended service life on metal
• Cloth backing provides flexibility and durability under load
• 60 grit medium grade balances cut rate with surface finish quality
• 8,600 RPM maximum speed rating for use on standard 7-inch angle grinders
• 7/8-inch arbor hole fits common angle grinder spindle sizes

Compatibility

Designed for use on 7-inch angle grinders with a 7/8-inch arbor spindle. Verify that the grinder's no-load RPM does not exceed the 8,600 RPM disc rating before mounting.

Installation Notes

Installation and disc changes must be performed with the grinder unplugged or the power source locked out. Always inspect the disc for cracks or damage before mounting and never use a disc that has been dropped or shows visible defects. Tighten the arbor nut to the grinder manufacturer's specified torque using the correct spanner wrench. ANSI B7.1 and applicable OSHA standards govern safe use of abrasive wheels on portable grinders.
