Ruby Stones - 100mm

Gesswein Ruby Stones are made by Friatec-Degussit from pure, sintered crystals of synthetic ruby. No bonding material is used, so these stones are extremely hard and resistant to changes in shape. This is particularly important for quality precision grinding and finishing. Keep in mind, these stones cannot be classified in terms of "grit" but only in terms of "fine" "medium" and "coarse". 

Due to their outstanding resistance to wear, they are more economical to use than other comparable tools.

Use dry or with Gesswein Stoning Oil to grind, touch up or debur steel and carbide parts. Ruby stones are also recommended for use on materials such as glass, quartz and porcelain.

Ruby Stones are the ideal choice for deburring, blending, dressing, and fine polishing of molds & dies made of hard metals such as hardened tool steel, carbide and surgical stainless steel. Jewelers use them for sharpening of carbide and high speed steel engravers and other tools.

Medical Instruments: Fine polishing of surgical stainless steel instruments.

Jewelers and Engravers: Polishing and shaping of carbide & high speed steel gravers.
