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

Does an excellent job honing cylinder walls. Makes it easy to get a perfect cross thatched finish. For this price it is a very good tool.

Works as it should, does the job. Its not perfect lol, its a dingle hone, so dont expect machine level results. But if youve got a thin bit of surface rust, or youre just a cheap slop like myself who needed to hone the cylinders in my junky rally car. Its great.

Fast, easy to work, very little mess to clean up

Easy to use and did the job perfectly. Will be getting more when I need them.

There is nothing to dislike about this hone. It does exactly what it is suppose to do. Been using these hones on motorcycle cylinders for years and they work great everytime.

Worked great for a stock bore 5.3/4.8 vortec

Worked nicely for my situation. Little bit pricey though.

Buy exact fit to the .10 or one .10 larger Working on a 22r Toyota stock bore 3.6. This hone did its job with a nice cross hatch. However, the hone just barely hit the bore walls. Maybe this is by design but I feel I should have gotten the 3.75 bore hone as my bore size is 3.6 If your bore is 3.5 then you would be fine. The hone would have a bit of pressure on the bore walls. If you plan on honing a 22r look for the next size up. The balls on the hone wore down Farley fast making flat spots on most the balls. So when you use this you do not want to hone one bore at a time. Make like 2 passes per bore to break in the hone tell you have broke the glazing off the bore walls and broke in the hone, then work on your cross hatch pattern. Over all I like this hone and its ease of use but the fact that I most likely will not be able to use it again, I may get one more use from it in 5-8 years witch would pay for it self then but a stone hone would be more cost effective. If you build the same 3.5 size bore engine all the time this hone would be ideal. Cause you can just grab put in drill and hone (adding cutting oil).

Got the hone oil a must to keep it wet. My option.

Works excellent may seem to big or tight but its supposed be that this is for a 3in cylinder bore
