Milwaukee 4" Carbon Steel Knot Wire Cup Brush 5/8"-11 48-52-1350
AGGRESSIVE MATERIAL REMOVAL FOR PROFESSIONAL METAL FINISHING
High-torque grinding applications demand an accessory that can withstand extreme heat and friction without premature wire fatigue. This knot wire cup brush is engineered with Hyperwire™ construction, specifically designed to maximize surface contact and material removal rates on structural steel and heavy castings. When mounted to a 7-inch large angle grinder, the precision-balanced design minimizes spindle vibration, protecting the tool's motor and gear set while reducing operator fatigue during prolonged cleaning or scale removal tasks. The high-grade carbon steel construction ensures the knots maintain their integrity under heavy load, providing a consistent finish across large surface areas.
- / Hyperwire™ Construction delivers significantly faster material removal and extended accessory life in high-abrasion environments.
- / Precision-engineered balance reduces tool vibration, ensuring smoother operation and protecting the internal components of your 7" grinder.
- / Heavy-duty knot wire design provides the aggressive scrubbing action required for removing heavy rust, scale, and weld spatter.
- / Universal 5/8"-11 threaded spindle ensures a secure fitment on all standard large-angle grinders.
