Weiler 96241 Flap Disc 40 Grit 4.5 Inch Type 27 Zirconia Alumina

Product Description

The WEILER 96241 is a Type 27 coated flap disc designed for aggressive material removal on steel and stainless steel. Part of the Big Cat series, it features a 40-grit zirconia alumina abrasive bonded to cloth flaps and mounted on a phenolic backing. The 4.5-inch disc is rated to 12,000 RPM and attaches via a standard 7/8-inch arbor hole. It is built for coarse-grade grinding tasks and is a common tool for welders, fabricators, and metalworkers who need fast stock removal and surface conditioning in a single disc.

The WEILER 96241 is suited for flat and beveled grinding applications on ferrous and stainless steel surfaces. Typical uses include weld bead removal, surface preparation before coating or inspection, and deburring on fabricated steel components. The Type 27 flat profile keeps the disc parallel to the workpiece, making it well matched to flat-surface grinding passes on plate, pipe, and structural steel in both shop and field environments.

Key Features

• 40-grit zirconia alumina abrasive for aggressive, coarse-grade stock removal
• Type 27 flat profile for flush grinding on flat and low-angle surfaces
• Phenolic backing provides rigidity and durability under sustained load
• Cloth flap construction delivers consistent cut rate throughout disc life
• Rated to 12,000 RPM for compatibility with standard 4.5-inch angle grinders
• Suitable for steel and stainless steel applications

Compatibility

Designed for use on steel and stainless steel. Fits standard 4.5-inch angle grinders with a 7/8-inch arbor. Rated applications include weld removal and surface preparation.

Installation Notes

Installation is performed by licensed or qualified metalworkers and fabricators using a 4.5-inch angle grinder. Ensure the grinder is unplugged or the power source is de-energized before mounting or removing the disc. Verify the grinder RPM rating meets or exceeds 12,000 RPM before use, and inspect the disc for damage prior to each use. Always use the appropriate guard and personal protective equipment per ANSI B11 and OSHA standards for abrasive wheel operations.
