In addition, since Gesswein Ruby Stones have an 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.
All are 100mm (4") long, medium grit in a variety of shapes & sizes.
*All dimensions have tolerance of ±0.1mm.
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.
Mold & Die Uses:
- Deburring ejector pin holes.
- General deburring and edge breaking on mold steel and carbide.
- Blending a surface where a straight edge meets a radius.
- Polishing highly detailed areas on dies (after dressing Ruby Stone to a fine point).
- Ruby Midget Files (see "Related Products" below) can be used in an Ultrasonic Handpiece for fast deburring and blending in ribs and other hard to reach areas. Ruby Stones cut faster than our very popular Super Ceramic Stones.
- Fine polishing of surgical stainless steel instruments.
- Polishing and shaping of carbide & high speed steel gravers.
Because Degussit DD57 is a homogenous ceramic material which is bondfree, these stones cannot be classified in terms of "grit" but only in terms of the average grain size. The average grain size of types "fine" and "medium" is about 10µ. Type "coarse" has two average grain sizes at about 10µ and 100µ.
No bonding material is used, so these stones and files are extremely hard and resistant to changes in shape. This is particularly important for quality precision grinding and finishing.
