3M bristle disc selection guide

Practical information from The Sandpaper People for professional shops and production teams.

Start with the job

Record the base material, coating or residue to remove, area to reach and required finish. Include your current product number when replacing an existing abrasive.

Match the disc and tool

Confirm the diameter, centre hole or attachment, brush assembly and required accessories. A replacement radial disc and a complete brush assembly are different products. Check the exact item supplied.

Check operating limits

Use the product and accessory instructions to confirm operating limits. Do not select a speed by colour or diameter alone. Follow the manufacturer instructions and your workplace safety procedures.

Check grade and ordering unit

Confirm the exact grade and stock number, selling unit, minimum quantity and order increment. Test a proposed replacement on a suitable sample before changing a production process.
