Weiler 85794 Silicon Carbide Crimped Disc Brush 180 Grit

Product Description

The WEILER 85794 is a 3.5-inch silicon carbide crimped disc brush designed for surface finishing, deburring, and light material removal on hard surfaces. It runs on a plain hole connector and features a very fine 180-grit abrasive filament, making it well suited for applications that require a consistent, refined finish rather than aggressive stock removal. The brush carries a maximum speed rating of 2,500 RPM and uses round filaments with a 0.035-inch diameter. It weighs 0.25 pounds and is typically installed by machinists, fabricators, or surface finishing technicians working with bench grinders or rotary finishing equipment.

This disc brush is used in light deburring, surface blending, and finish work on metals, ceramics, and composite materials where silicon carbide abrasive is the appropriate media. The 3.5-inch outside diameter and 1.5-inch trim length make it a practical fit for smaller rotary tools and bench-mounted grinders. The plain hole arbor opening measures 0.875 inches, suiting standard arbor configurations found in common shop equipment. It is sold individually as a single-unit package.

Installation Notes

Installation and replacement should be performed by a qualified technician or machinist following standard shop safety procedures. Always power down and disconnect the grinder or rotary tool before mounting or removing the brush. Confirm the tool spindle speed does not exceed the 2,500 RPM maximum rating marked on this brush. Inspect the arbor and mounting hardware for wear before securing the brush in place.
