Cherry Oilstone, Square, Fine Grit, 150x50x25

This is a new item. I received it as a gift from a friend but am selling it because I don't have the opportunity to use it.

This is an oil stone that is used by soaking it with oil such as kerosene or grinding oil.
It is made of A grit and has a wide range of grit sizes, high stone strength, and is resistant to shape deformation.
Ideal for removing gasket residue from cylinders (cast iron) and deburring.
