"I got the 1-1/8" (28.6mm) hone, but I noticed that the outside diameter actually measures 1-1/4" (31.75mm). Am I missing something here?"

They really helped with proper oiling and the piston break-in. After some practice, I managed the honing technique well, and the results were fantastic. I highly recommend this product and the seller!"

"When I was replacing a leaking cartridge in my Moen Positemp shower valve, I needed a flex hone to clean the inside of the valve body. I used this product and it was perfect for cleaning corrosion and scale, leaving a pristine surface for the new cartridge. I've used these hones on engine cylinders for years, so I knew it would work. While they are a bit pricey, it was still less expensive than replacing the whole faucet assembly!"

"I uploaded a before and after picture because it really speaks volumes about the results. This hone works wonders on nikasil without removing material. The bore size remained the same before and after honing. I definitely recommend giving it a try!"

"I recently got a Savage .308, but had issues with the bolt extracting rounds. After using this hone, it worked great! Now it runs fine with 7.62 and .308."

“I decided to rebuild my snowmobile motors for preventative maintenance, replacing pistons and rings. The piston suppliers recommended these ball hones for cylinder prep.

The 320 grit Aluminum Oxide versions worked perfectly for de-glazing and refreshing the crosshatch, ensuring proper cylinder oiling and piston and ring break-in.”

“I used this to remove rust from a motorcycle engine barrel. After I finished, it looked like it was freshly honed. It took about an hour to do two barrels, and I highly recommend this brush. You won't be disappointed!”

"The Dingle Berry Brushes I’ve used for years have provided the best results. I bought this set for various projects, especially for deburring lifter bores. They left a nice oil-holding finish, and overall, this kit is worth the investment!"

“I used this with a drill to clean out my outboard motor tilt tube that had rusted and frozen my steering cable. After driving the rusted cable out, the hone tool worked perfectly to clean the .625 inch bore for my new steering cable installation.”

“I honed a 70mm dirt bike cylinder with this tool. It performed well for a quick top-end rebuild, and I was pleased with the results.”
