DEGUSSIT® Ruby® Stones, 4" RoundGesswein Ruby Stones and Files 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. 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

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, coarse 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.
These fine grinding stones are made of Degussit DD57 (sintered ruby) which is a homogenous mixed-crystal material. The main element is aluminum oxide. The characteristic red colour is the result of an admixture of chromium oxide.
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.

Affordable and classy
Size: Medium, Color: Light Brown, Size: Medium, Color: Light Brown
I have five stars even if the best was a little short. I have a tall boy and the rest is totally worth the money. Fit was as marked aside from vest which is higher on the chest than necessary. It was comfortable for him and durable. Gonna keep for any need in the future. He wore it to prom and it was awesome.

3 piece suit at a great price
Size: Small, Color: Black
My son needed a suit, and these worked out great. It looks nice. Don't just assume the size, go by their size chart. I was going to order him a medium, by the chart recommended a small, and it fit perfect. The material doesn't look like an expensive suit but it worked out great for him.

10/10 Great suit , great price
Size: X-Small, Color: Red, Size: X-Small, Color: Red
Absolutely stunning for the price. Very flexible and good fit. I wish the XS was just a bit smaller but it's good. Middle of the ground with thickness it's not a cheap thing costume feel but it's not your typical heavy suit. Which I much prefer. It's lightweight but not cheap. For the price you can't ask for a better suit. I was thinking it was more of a one time use, but it's a very good long term suit. Feels very well and allows great mobility. I featherweight conceal carry and it's very easy to hide my pistol in the suit because of its flexibility. 10/10 would definitely recommend
