Ronix RH-9940 mounts to M14 spindles for aggressive rust removal and surface cleaning. Brass-coated 0.3mm steel wires sustain structural integrity at 12,500 RPM. Under high rotation, the crimped structure strips paint and weld spatter from metal workpieces without damaging the base material.
Key Features
- Brass-Coated Wire: 0.3mm crimped steel bristles resist corrosion and stop wire snapping. High-elasticity metal maintains shape during polishing.
- 12,500 RPM Rating: Safety-rated for high-speed operation on 4-inch angle grinders. Wires won't fly off during intense cleaning.
- M14 Arbor Thread: M14 x 2 sizing fits standard angle grinder spindle threads. Direct mounting prevents wobbling during heavy vibration.
- 75mm Cup Diameter: Compact 75mm size cleans tight corners and flat metal. Smaller profile reduces torque strain on motors.
