HOMO FABER 12 Pack Wire Wheel Brushes for Angle Grinder, 4-1/2", 5/8"-11

Key features

• 1. Get 3x 4" knotted wire wheels, 3x 4" crimped wire wheels, 3x 3" knotted cup brushes and 3x 3" crimped cup brushes in one set — three sizes and two wire types, so you can switch between heavy rust removal and light surface finishing without buying separate brushes. Each wheel is separate packaged and sorted by size and type. Fits 4-1/2" angle grinders with a 5/8"-11 arbor.
• 2. Standard 5/8"-11 UNC threaded arbor threads directly onto most 4-1/2" angle grinders by hand — no adapters, no special tools. The threaded mount seats flat against the spindle for a wobble-free fit, so the brush runs true at speed instead of chattering against the workpiece.
• 3. 0.020" knotted wire and 0.014" crimped wire are locked in place by a thickened double holding plate for strong wire retention, keeping each brush balanced up to 12,500 RPM. This structure reduces wire breakage and fly-off during heavy pressure work, so the brush holds its shape through repeated rust and weld cleaning jobs. Under moderate rust removal, a knotted wheel typically covers a large area before the wire tips round off.
• 4. Built for auto body repair, welding shops and metal fabrication: strip rust from truck frames, large flat panels and heavy steel plate, remove weld slag and spatter, clean scale before painting, and prep bare metal for powder coating. The 4" wheels handle flat surfaces and edges, while the 3" cup brushes for angle grinders reach into corners and tight welds.
• 5. Confirm your grinder: this set fits 4-1/2" angle grinders with a 5/8"-11 threaded arbor. Not for M14 metric spindles — 5/8"-11 UNC only. Carbon steel wire is not recommended for stainless steel, to avoid cross-contamination. Let the wires do the work and avoid heavy downward pressure to extend brush life. Always wear safety goggles and gloves, and keep the grinder under 12,500 RPM. Store brushes in a dry place between jobs.
