Miniature Nylox Disc Brush 80SC

The Weiler 85981 is a 3-inch miniature Nylox disc brush built for precision surface finishing. It targets machinists and fabricators who need consistent deburring on flat components, face-milled castings or forgings. The silicon carbide fill with 80 grit rating handles aluminum faces and blending tasks after machining or grinding. Maximum density crimped rectangular filaments deliver uniform contact across the workpiece.

Verify spindle fit and speed limit

Confirm your tool accepts a 3/8-inch center hole before ordering. The brush is rated for 4500 rpm maximum; do not exceed this speed on your grinder or CNC spindle. Ensure the 1-1/4-inch trim length clears your fixture and workpiece geometry. Check that the .100 by .050-inch filament dimensions suit the material hardness and finish specification you require.

Precision cup and USA manufacture

A machined aluminum cup holds the crimped rectangular fill securely during high-speed operation. This construction resists vibration and maintains filament alignment for repeatable results. Made in the USA at a facility certified to ISO 9001 standards since 1898 heritage. The medium-grade 80SC abrasive balances cut rate with surface quality for daily shop use.

Questions about this item

What comes in the box and what else do I need to buy?

The box contains one Weiler 85981 miniature Nylox disc brush with a 3 in diameter, 3/8 in centre hole, 1-1/4 in trim length and 80 grit silicon carbide fill. You must supply a compatible power tool that accepts a 3/8 in arbor and can run at or below 4500 rpm.

Which version of the 85981 should I choose for my application?

This model is a single specification: 80SC crimped rectangular fill, maximum density, medium grade. Choose it when you need aggressive deburring of flat machined faces, face-milled castings or forgings, or blending of grinding marks on aluminium and similar metals.

What does the 4500 rpm maximum mean when the brush is on my machine?

It is the absolute speed limit for safe operation. Run the brush at or below 4500 rpm on a tool with a 3/8 in arbor; exceeding this speed can cause filament failure and unsafe conditions.
