> 3 dayUsed this for refinishing a plow piston cylinder. A lot of people complaining about the price but this is much cheaper than any other available option, whether sending out to get machined or buying and actual hone setup for at home.

> 3 dayThis is a great upgrade over regular 3 blade hones, especially for those that dont have much experience with regular hones. This hone is very easy to use and works very well, make sure you use a good lubricant while you hone, 10w30 oil is what I used. The one major downside to this and any other ball hone, over a regular hone, is that you can only use this hone for the specific size cylinders. Where 3 blade hones can be used for several different size cylinder bores. Other than that I would highly recommend this hone, it worked flawlessly for me.

> 3 dayExactly what you need to prep a new Nikasil cylinder for new rings. This will remove material quickly, which is what you need to set in a nice hash pattern in Nikasil. However, you only need a slow speed (low gear on most drills) and only 3 or 4 oscillating strokes. Good luck.

Greater than one weekI have personally relied on products from this company for a very long time in a professional setting. As far as ball Hones go Flex-Hone is the best and has been. The quality is top notch and the number of sizes they make are unequalled by any other company

> 3 dayPurchased 76mm for honing an old ATV cylinder. Some WD40 and several passes later the bore is cleaned up and has a nice surface for the new piston rings to seal in. Cleanup is easy with carb or brake cleaner. Make sure to get the right size hone for your bore!
