3" Twist Knot Wire Cup Brush M14x2

Small footprint, serious cutting power — this 3" (75mm) twist knot wire cup brush is built for detailed metal prep work where a larger wheel just won't fit. The tightly twisted wire knots hold together far better than standard crimped wires, letting you strip rust, flaking paint, and weld residue without the brush wearing down or fraying apart mid-job.

Its compact 3" size makes it a natural fit for tighter spaces, edges, and detail work that a bigger 4" or 5" brush would struggle to access — think corners, small brackets, pipe fittings, and narrow welded seams. Despite the smaller diameter, it's rated to a high 12500rpm, so you're not sacrificing cutting speed for size. The M14x2 arbor thread means it mounts straight onto standard angle grinders with no adapter needed.

This is the brush to reach for when you need precision along with power — cleaning up small parts, prepping hardware before painting, or getting into corners a full-size cup brush can't touch.

Where it works best:
Detail rust and corrosion removal on smaller parts and brackets, cleaning welded joints and tight corners, paint and coating removal in confined spaces, general metal prep on hardware and fittings.

Key Features:

• ✅ Compact 3" (75mm) diameter for tight spaces and detail work
• ✅ Twisted knot wire construction resists fraying under pressure
• ✅ M14x2 arbor fits standard angle grinders
• ✅ High maximum speed rating of 12500rpm
• ✅ Strips rust, paint, and weld residue effectively
• ✅ Ideal for small parts, brackets, and hard-to-reach areas

If your work involves smaller components, tight corners, or detail prep rather than wide flat surfaces, this compact cup brush gives you the reach and speed to get it done properly.
