PROMAX Coatings
We coat all of our PROMAX Premium and Design-Rite XL products are manufactured in our very own High-Performance Coating Center. Having the entire coating process In-house enables us to ensure the highest coating quality. Our coating center is supported by the R&D department of our sister company in Germany. With their help, we are able to bring the latest European technology to the US market.

PROMAX PowerLayer
We are proud to announce that we have successfully launched our new coating PROMAX PowerLayer. This technology is a game-changer for our PROMAX Premium products. Internal tests have shown that tool life compared to AlTiN can be improved by up to 100%. In combination with our new 4-Flute series US007 and our 5-Flute series US556, we now offer the highest performance end mills on the US market. The PROMAX PowerLayer coating works in all steels, high temparature alloys and titanium.


 
 
PROMAX AlTiN
Aluminium Titanium Nitride (AlTiN). Also branded as TAliN by other manufacturers, AlTiN is the classic high-performance coating on the US market. Our PROMAX AlTiN is able to outperform similar coatings through our consistency of coating thickness. In our In-house coating center we control the distribution of tools inside the coating machines, which determines the coating quality. Our PROMAX AlTiN is extremely heat resistant which shows great results when cutting Nickel based Alloys, Stainless Steel, Hardened Steels, Tool Steels and Titanium.


PROMAX ZrN
Zirconium Nitride (ZrN). This monolayer coating effectively reduces built-up edges when machining aluminum and titanium alloys. While usually recommended when machining medical grade materials and in other high heat resistant applications, it is also for use in machining steels, alloyed steels, superalloys, Aluminum > 12%  Si, Aluminum < 12% Si, copper, bronze, brass and plastics. Our PROMAX ZrN is able to outperform similar coatings available on the US market through our consistency of coating thickness. In our In-house coating center we control the distribution of tools inside the coating machines, which determines the coating quality.


 
nACRo®
Our nACRo® follows the coating structure of the original nACRo® coating developed by PLATIT, a swiss developer of coatings and coating machines. nACRo® has a nanocomposite structure that has increased hardness for scratch and higher heat resistance. This coating excels in “tough” difficult to cut materials including Steels, Hardened Steels, Alloyed Steels, and Superalloys.
