Jewelers and Engravers:

• Polishing and shaping of carbide & high speed steel gravers.

Mold & Die Applications:

• Use in an Ultrasonic Handpiece for fast deburring and blending.
• 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)
• Polishing ribs and other hard to reach areas.

About Degussit Ruby Stones:
Made in Germany from pure, sintered crystals of synthetic ruby. 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.

In addition, since Degussit Ruby Stones and Files feature outstanding resistance to wear, they are more economical to use than other comparable tools.
