Weiler 85852 Silicon Carbide Crimped Disc Brush 6 in

Product Description

The WEILER 85852 is a 6-inch silicon carbide crimped disc brush designed for surface conditioning, deburring, and finishing on a wide range of metals and hard materials. It runs at a maximum of 2000 RPM and carries a fine-grade, 120-grit abrasive filament with a round filament shape and a filament diameter of 0.04 inches. The plain hole connector and 7/8-inch arbor hole allow straightforward mounting to compatible spindles. The 1-1/2-inch trim length provides consistent abrasive contact during operation. Machinists, tool-and-die technicians, and fabricators working on automated or manual equipment install this brush type as part of surface-prep and finishing workflows.

This disc brush is suited for use on aluminum, brass, bronze, cast iron, ceramic, copper, high-nickel alloy, soft tile, stainless steel, and steel. It is compatible with CNC machines, milling machines, and automatic machines, making it a practical choice for both production-line and job-shop environments where consistent abrasive action across varied substrates is required. The gray silicon carbide filament resists loading on non-ferrous and harder materials where aluminum oxide would break down more quickly.

Key Features

• 120-grit fine-grade silicon carbide abrasive for controlled stock removal and surface finishing
• 6-inch outside diameter with 1-1/2-inch trim length for consistent brush contact
• Plain hole connector with 7/8-inch arbor hole for quick, secure spindle mounting
• Rated to 2000 RPM maximum for safe use on CNC, milling, and automatic machines
• Round filament shape at 0.04-inch diameter delivers uniform abrasive action across the work surface
• Compatible with a broad material range including stainless steel, cast iron, copper, and ceramic

Compatibility

Designed for use on CNC machines, milling machines, and automatic machines. Suitable for deburring and finishing aluminum, brass, bronze, cast iron, ceramic, copper, high-nickel alloy, soft tile, stainless steel, and steel substrates.

Installation Notes

Installation is performed by machinists or tool technicians familiar with rotary abrasive tooling. Power down and lock out the machine before mounting or removing the brush. Verify the spindle arbor size matches the 7/8-inch arbor hole before installation and confirm operating speed does not exceed 2000 RPM. Inspect the brush for filament damage before each use and never exceed the rated maximum RPM.
