Custom Cup Brushes

When should you choose this brush type?

Choose a cup brush when a broad rotating face needs to work on an accessible surface such as plate, castings, weld areas, or open contours. Choose a wheel brush for narrower edge or profile contact, or an end brush for a confined recess where the cup body blocks access.

What are Cup Brushes?

Cup brushes set wire or abrasive filament into a cup-shaped body so the working ends contact the surface as a broad rotating face. They are used for rust, paint, scale, weld discoloration, deburring, and surface preparation on plate, castings, and accessible contours.

Diameter, cup profile, trim, fill construction, thread or arbor, and customer-supplied tool conditions control coverage and aggression. Straight or crimped fill is more conformable; knotted wire increases cutting action; abrasive nylon offers more controlled conditioning and lower wire-break risk.

What dimensions can I customize?

Head diameter	65–75 mm
Head or working length	25–30 mm
Mounting interface	Threaded Removable

Where is this brush type commonly used?

Start with the job the brush needs to do, then confirm dimensions, contact direction, material, and mounting.

What configurations are available?

Crimped-wire cup

Flexible wire face for general cleaning, light scale, paint, and irregular surface contact.

Knotted-wire cup

Twisted wire bundles for heavier deposits and aggressive preparation on robust metal surfaces.

Abrasive-nylon cup

Grit-bearing filament for controlled deburring, blending, and finish-sensitive conditioning.

Flared cup

An outward working angle increases edge reach and coverage around contours.

Compact straight cup

A more contained face for localized cleaning and smaller tool envelopes.

What material is right for this brush type?

Carbon steel wire

Heavy cleaning on ferrous surfaces where carbon contamination is acceptable.

Stainless steel wire

Corrosion-resistant metallic cleaning and reduced carbon-steel contamination risk.

Brass wire

Softer wire action for suitable parts and lower-aggression surface cleaning.

Silicon carbide or aluminum oxide nylon

Controlled abrasive action selected by grit, filament diameter, and finish target.

Filament materials to compare

What do I need to know before ordering?

Specify the surface material and area, residue, desired finish, cup diameter and profile, thread or arbor, tool and guard clearance, rotation direction, customer-supplied speed, contact angle, and quantity.

Questions this page is asked

Why must a cup brush be checked at running speed for clearance?

The fill can flare beyond the stationary diameter and change its contact band as speed and pressure rise. Verify clearance from guards, shoulders, fixtures and adjacent surfaces at the approved speed, and stop if the brush contacts outside the intended face or becomes unstable.

How should a cup brush be accepted for a finished surface?

Trial the identified brush on representative material with the approved speed, angle, pressure and dwell, then inspect for profile change, staining, embedded wire and coating damage. Retire it for loose or missing fill, severe flare, cracked mounting, cross-material contamination or vibration that remains after cleaning and correct installation.
