FLEX-HONE RMFH60Z25 Brake Rotor Hone, 2-1/2" Diameter, 60 Grit Zirconia Alumina
The Brush Research RMFH60Z25 Flex-Hone is a coarse-grade brake rotor and flywheel finishing tool featuring a 2-1/2" diameter and 60 grit zirconia alumina abrasive. Designed for heavy-duty resurfacing tasks—such as removing glazing, corrosion, or poor machining marks—it produces a non-directional, plateau-style finish that enhances brake pad seating and reduces noise and vibration.
- Features:
- Patented Flex-Hone® technology creates a non-directional “basket-weave” pattern—specifically engineered to lower harmonic vibrations and eliminate brake noise.
- Coarse 60 grit zirconia alumina abrasive effectively removes torn, folded, or glazed metal from rotors and flywheels.
- 2-1/2" diameter size fits most standard automotive brake rotors and clutch plates.
- Durable construction enables resurfacing of multiple rotors, outperforming conventional abrasive pads.
- Made in the USA by Brush Research Manufacturing, ensuring premium quality and consistency.

The FLEX-HONE RMFH60Z25 can also be referred to as coarse rotor hone, 2-1/2" rotor hone, zirconia alumina flex-hone, non-directional rotor brush, and brake surface conditioner.
Brush Research Manufacturing has been at the forefront of surface finishing innovation for over 60 years. Their rotor-specific Flex-Hone tools are trusted in professional automotive and service settings to provide consistent, high-quality finishes that improve braking performance and customer satisfaction.
Q: When should I choose the coarse 60 grit version?
A: Use 60 grit when resurfacing heavily glazed or poorly turned rotors, heavy-duty vehicles, or flywheels to remove aggressive material and prepare the surface for pad seating.
Q: Can I use it with a handheld drill?
A: Yes—use a variable-speed drill or brake lathe at 300–600 RPM (max 1,000 RPM), with light pressure and dry operation in timed intervals.
Q: How does this compare to 120 or 240 grit?
A: The 60 grit is coarser and more aggressive, ideal for heavy-duty material removal; 120 and 240 grits are finer for standard pad seating or aesthetic finishes.
Q: How many rotors can I expect to hone?
A: It outlasts abrasive pads, allowing multiple rotors per tool; tool life depends on rotor condition and usage method.
Q: Is lubricant required during use?
A: No—this tool is designed for dry use only. Follow the specified timed intervals to avoid overheating and bond damage.
