⚡ At a Glance
- • Abrasive Action: Heat-resistant nylon filaments with embedded grinding grains, gentle on metal and wood
- • Best for: Light to medium surface preparation, paint roughening and rust removal on uneven surfaces
- • Not ideal for: Heavy stock removal or scale stripping where wire brushes are necessary
Pot-shaped nylon cup brush, 63.5 mm diameter, supplied as a pack of two. Fits common threaded angle grinders and runs up to 8500 RPM when used at recommended lower speeds.
Reliable paint and finish preparation - with heat-resistant nylon filaments and grinding grains
Nylon bristles carry abrasive grains that scour surfaces without the aggressive cutting action of wire. The pot-shaped cup spreads contact across larger, uneven areas for even abrasion at lower speeds.
Roughens old paint and prepares wood or metal for repainting while reducing the risk of gouging. Suitable for tasks like prepping loading areas or barrel staves for refinishing.
Safer metal cleaning - with spark-free nylon abrasives
Nylon-based abrasives generate no sparks and do not corrode, unlike metal wire brushes. Bristles remain dimensionally stable and show minimal loss compared with wire alternatives.
Useful for indoor or wet work where sparks are a hazard, and for cleaning metal components without causing surface damage.
Controlled, quick maintenance - with a pot shape and common thread fit
The 63.5 mm pot design reaches into curves and uneven profiles, while compatibility with 5/8-11 threaded angle grinders, polishers and 1/4 inch drill press threads simplifies attachment. Recommended operation at lower speeds avoids bristle bending.
Makes short work of tasks like whisky barrel stave char removal and routine rust clean-up, letting workshops finish maintenance quickly and predictably.
