That makes it difficult to predict the life of a tool. However, the use of proper reactor conditions and selecting compatible carbide chemistry can help solve this problem and achieve smooth wear patterns. Here are known facts about diamond tools.

Diamond-Coated Tools Can’t Work on Hardened Steel

Diamond is made up of carbon atoms. Some materials such as iron can absorb carbon to form carbides when subjected to extreme heat. When machining materials using diamond-coated tools, friction provides the heat needed to cause the carbon atoms to diffuse into the iron, causing the film to wear out. That way, the diamond tool can’t pay itself due to premature wear and tear.

Diamond-Coated Tools Have a Varied Lifespan

The lifespan of a diamond-coated drilling or cutting tool can vary depending on the material cuts and the geometry of its parts. A diamond-coated drilling tool can last 20 times as long as an iron or carbide tool and can last even longer than that in some cases. Diamond-coated tools don’t need frequent recalibration; thus, they don’t cause interruption.

There Is No Guarantee for a Recoated or Sharpened Diamond Tool

It can take long to sharpen a tool using a diamond wheel since the film is usually a pure diamond. Moreover, the chemistry of a diamond-coated tool is often altered when preparing it for diamond growth. As such, it’s not possible to guarantee the results of a recoated or sharpened tool because users need to manage its chemistry very closely.

Wearing out has been a severe problem with diamond-coated tools. However, it’s still possible to eliminate the issue of diamond peeling off through the use of proper reactor conditions and suitable preparation techniques. Diamond films can last much longer than graphite if peeling off is prevented.
