Weiler 86113 Ceramic Crimped Disc Brush 4 in 120 Grit

Product Description

The WEILER 86113 is a 4-inch ceramic crimped disc brush designed for surface conditioning, deburring, and finishing on a wide range of metals and hard materials. Rated at a maximum of 2500 RPM, it uses ceramic abrasive filaments in a round crimped configuration to deliver consistent, fine-grade cutting action at 120 grit. The drive arbor connector and 1-1/4-inch arbor hole allow straightforward mounting to compatible spindles. With a 1-1/2-inch trim length and a weight of 0.7 pounds, the brush balances durability with controlled material removal. It is intended for installation and use by machinists, fabricators, and tool-room technicians.

This disc brush suits applications 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 appropriate for both production and tool-room environments where repeatable, fine-grade surface finishing is required. The ceramic abrasive construction handles harder alloys and high-nickel materials where conventional abrasives lose cutting efficiency.

Compatibility

Designed for use with CNC machines, milling machines, and automatic machines equipped with drive arbor spindle connections. Suitable for material applications including aluminum, brass, bronze, cast iron, ceramic, copper, high-nickel alloy, soft tile, stainless steel, and steel.

Installation Notes

Installation is performed by machinists or tooling technicians. Always power down and lock out the machine before mounting or removing the brush. Confirm the spindle RPM rating does not exceed the brush maximum of 2500 RPM before operation. Inspect the brush for filament damage or deformation prior to each use and replace if the trim length is worn beyond effective contact.
