Abstract
This invention relates to a solution and process for chemically resharpening smoothing, forming, and cutting tools such as files, jigsaw blades, hacksaw blades, coping saw blades, bandsaw blades, and the like. The solution contains preferred concentrations of phosphoric acid, anionic and nonionic surfactants including ethyl alcohol and distilled water. The tools are immersed in the solution for a period of 2 to 5 hours depending upon the wear to the tools, after which the tools are removed, wiped, and allowed to air dry to allow a rust resistant coating from the solution to adhere to the tools.
Claims4
A process to chemically resharpen or sharpen forming, smoothing, and cutting tools which comprises:
- providing an aqueous solution of from about 1% to 20% by volume of anionic and nonionic surfactant with ethyl alcohol, phosphoric acid of from about 5% to 92% by volume, and distilled water in a volume sufficient for the balance of said solution;
- completely immersing said tools in said solution;
- subsequently removing said tools from said solution;
- drying said tools;
- and
- allowing a rust resistant coating of said solution to adhere to said tools.
