4.5" Ceramic Bristle Disc for Metal Surfaces

The 3M 24241 is a 4.5-inch green bristle disc with a P50 grit rating designed for use on right-angle grinders. Its ceramic bristles target aluminum, brass, bronze, cast iron, stainless steel and steel. The disc mounts via a 5/8 in.-11 threaded hole and is rated for a maximum operating speed of 12,000 RPM.

Suited for Aggressive Blending on Compatible Metals

This disc serves fabricators and metalworkers who need fast material removal and surface blending on the listed alloys using a right-angle grinder. It is not intended for users who require a quick-change mounting system, a finer grit finish, or a brush configuration compatible with tools other than right-angle grinders.

Sustained Performance at Rated Speed

Under continuous operation at up to 12,000 RPM the ceramic bristles maintain their cutting action across aluminum, brass, bronze, cast iron, stainless steel and steel. The fixed threaded-hole mount keeps the disc secure during extended grinding sessions without the vibration that can occur with worn or loose quick-change adapters.

Questions about this item

Will the 5/8 in.-11 threaded hole on the 3M 24241 fit my right-angle grinder spindle?

The disc has a 5/8 in.-11 threaded hole and is listed for right-angle grinders; match your spindle to that thread size before mounting.

Can I run this 4.5 in. ceramic bristle disc at the same 12,000 RPM I use for my older abrasive wheels?

The maximum operating speed is 12,000 RPM; do not exceed that limit even if your older wheels were rated higher.

How do I confirm the 50 grit ceramic bristles are removing material correctly on stainless steel?

Expect a consistent, uniform scratch pattern and steady material removal without loading; the green colour remains visible while the bristles wear evenly.
