Anyone tried these stones for polishing bevels?

[Case_D]

I was looking over Congress Tools' website to get some stones for polishing bevels. I know everyone talks about using their EDM stones, but I was looking at all the options. I saw they offer a stone they call Diamond Ultra Stone. Has anyone tried these? I tend to use high wear resistant steels, so it peaked my interest. I'm tired of filling my trashcan with sandpaper.

Description from website:

The latest development in metal finishing and polishing is the DIAMOND ULTRA STONE. Similar in composition to the Ultrafine Ceramic Stone, the Diamond Ultra Stone features a matrix of diamond grit throughout the stone. This produces a more aggressive cutting stone and is available in 200, 400, and 600 grit.

The Diamond Ultra Stone is particularly effective when used in ultrasonic polishing, and will also produce great results in reciprocators or even when used by hand. These stones are very snap resistant and are recommended for use on all tool steels, carbide and other hardened or heat treated metals.


Thanks for any tips. I really appreciate y'all

Try 3m diamond microfinishing film for wear resistant steels. Expensive but cheaper than your time and way less frustrating than regular sandpaper

When you start to use them ? I mean in which stage of process ? After what ?

if you want to hand sand wear resistant steels.... belt grind to whatever u can, usually 220 grit and then hand sand with the 3m film.

Normal abrasives don’t work with z wear after 180 or so and the diamond film bites
