Engine Performance Booster
Being a motorsport engineer, the flex hone is my go-to for ensuring peak engine performance. I never skip the step of running the engine with this tool before reassembly, especially when honing isn't fully done. Its precision and efficiency elevate the process, delivering flawless results. I swear by the flex hone for a seamless and effective engine reassembly routine.

Perfect Finish Every Time
Used this to deglaze cylinders on a cast iron engine block. Left a nice crosshatch pattern and removed just enough material without overdoing it. Very forgiving and easy to use with a hand drill. Great tool for anyone doing rebuilds at home. Highly recommend.

Great Hone. Worth It.
Fantastic hone ! Iโm an old guy and hadnโt rebuilt an engine in decades, back then we used 3 stone hones, and nothing wrong with them. What I like about this type hone is the covered surface area is much greater, and the stone pressure is going to be more even over a smaller area. I just finished rebuilding a SBC and this hone is worth the money.
