Q: What types of vehicles is this hone suitable for?
A: The RMFH120Z25 is ideal for most passenger vehicles and light trucks with rotor sizes near 2-1/2". Always confirm rotor size for compatibility.
Q: Can I use this tool with a handheld drill?
A: Yes, it can be used with a handheld drill or brake lathe, as long as the RPM stays within 300–600 for best results and safety.
Q: What is the benefit of the 120 grit level?
A: 120 grit provides a balanced finish—aggressive enough for surface conditioning, yet fine enough to support fast brake pad seating and smoother stops.
Q: How long does the tool last?
A: With proper lubrication and use, the Flex-Hone tool can resurface multiple rotors. Tool life varies based on usage and material condition.
Q: What lubricant should I use with this hone?
A: Use standard honing oil or other suitable oil-based lubricants to extend tool life and optimize finish quality. Avoid solvents.
