Silicone Gray Flame-tip Tool - 240 Grit
3/16 inch shank
The diamond dust in this large and long-lasting tool is set in firm silicone and can be used again and again.
The low 240 grit is used to remove the upper layers of hard encrustations on coin surfaces before progressing to more gentle grits. To keep the point sharp, use the tool sideways whenever possible.
Like all of our DD Dremel tools, this works best under running water. Remember to use nearly zero pressure. Go slow and in circular motions as often as possible and at the lowest RPMs.
