Q: Wish one is best for a cylinder wall that is 75mm (2.95 inch) ?

For the cylinder wall bore size of 2.95", the 3" Flex-Hone is the correct choice., Enter this ASIN # B002N3AA2A in the Amazon search bar for the correct hone.

Q: Hello, my cylinder bore is 3 1/8" what size tool do i need to purchase thank you.

For a 3.125" bore, your application will require the 3-1/4" (3.250") diameter Flex-hone. The 3-1/4" will work perfectly in the 3-1/8" bore as the 3-1/4" Flex-hones working range is down to 3.000". Thank you for the inquiry.

Q: Can i use this to hone out an old cast iron pipe? it's about 3 3/4" now and i want it at 4" id. thanks

This hone is not coarse enough to remove that much material. It would take forever and the hone would wear out first. You would need a lathe to remove that amount of thickness.

Q: I see that it says tool is oversized. For a cylinder bore of 3.66, should I be getting the 3.75 or the 3.50 model?

1I bought a 4.50 and used it on a 3.55 bore with no problem I didn't hone as much as instruction said for large bore, hatch marks were beautiful so go bigger and you can use it over a broad area of bores.
