Brush Research FLEX-HONE Cylinder Hone, GB Series, Silicon Carbide Abrasive, 4-1/8 (105 mm) Diameter, 240 Grit Size

Works very well - easy to use if careful.

Works well as a hone. Keep in mind they dont have much range so you need the correct size, you cant squeeze this into a smaller cylinder. Youre gonna want your drill on slow speed and pretty aggressively stroke it in and out to get a 45 degree crosshatch.

It worked well for my SBC. I thought it should last longer than 1 V8 engine honing. Maybe its not supposed to, I dont know when I was done I noticed the dingle balls were smoothe.

This honing tool worked perfectly and now we’re ready to start the re-assembly of our engine.

I love this hone! It works great and no fuss. I used it on a 6.5 turbo diesel to remove surface rust and bring it back to running order for a rebuild

Good product and it got the job done on a golf cart engine that I was rebuilding but I did have some of the turds come off of it at the end of the hone. Worked very effectivly and once the few turds came off right away didnt have another issue with it. No more than I will be using it I couldnt justify buying an expensive one but I am still very pleased with this product cause it still got the job I bought it for done

Being a hobbyist rebuilder I am very happy with the results of this hone. Makes up for a mulittude of errors on my behalf in skill. I have a Lisle rigid hone and that works really well for the rough work but this made the final a finish factory finish. Seated perfectly

Should be in all tool boxes

I am no expert on cylinder homing, but had no issue using this hone. It worked as expected and my cylinders are now honed. Just a few seconds per cylinder and the job was done. I only needed it for 2 cylinders so I dont know how durable it is, but it seems like it is good quality to me.

deglazed my cylinders, and got it to work with my engine still in the car. only had to shorten it up
