PRomax powerlayer coating

PROMAX PowerLayer technology is a game-changer for PROMAX Premium products. The cutting edge PowerLayer coating was developed by a team of scientists in Promax's R&D facility in Germany. The combination of this high-tech coating with new, innovative geometry makes the US007 Series stand out among the crowd. Internal tests have shown that a tool life compared to AlTiN can be improved by up to 100%. The new Promax Premium 4-Flute Series US007 and the 5-Flute Series US556 End Mills represent the highest performance end mills on the US market.

PRomax series US007 4 FLUTE SOLID CARBIDE UNEQUAL INDEX & VARIABLE HELIX POWERLAYER COATED ROUGHING & FINISHING END MILLS

Designed for high performance milling on wide range of materials, Promax Series US007 End Mills are effective on steel, tool steel, stainless steel, titanium, high temperature alloys, cast iron, copper, brass, & ferrous aircraft and aerospace materials including hard aluminum. These USA-made end mills are available in regular, long, and extra long lengths, with 179 size and radius options, starting at 1/8" cutting diameter up to 1". This series excels with both lower and higher feeds and speeds, and there is no need to change feeds and speeds to make this tool work. Promax encourages you to push the tool to its maximum, and save even more cost in the form of reduced machining time.

The Series US007 was developed in Promax's R&D facility in Germany. An entire team of engineers spent weeks on engineering and testing of this tool, and out of over 20 developed and tested versions, this specific series US007 performed the best and was chosen to be released to the market. The geometry has variable helix, unequal index and a tapered core. The time and investment going into re-inventing this tool is unparalleled in the industry. 

Moreover, this series is proven to outperform competitor USA-made end mills as illustrated below, and the PowerLayer even outperforms Promax's own comparable AlTiN Coated End Mills! The US007 Series is hands down the best 4-flute end mill option (and value) on the market. Outperforming other 4-flute end mills by up to 100% while priced at a comparable or less expensive cost, in 2 years of US customer testing, it could not be beaten once. 

PRomax series US556 5 FLUTE SOLID CARBIDE UNEQUAL INDEX & VARIABLE HELIX POWERLAYER COATED ROUGHING & FINISHING END MILLS

Like the Series US007, the Series US556 End Mills are designed for high performance milling on wide range of materials. Promax Series US556 End Mills are effective on steel, tool steel, stainless steel, high temperature alloys, cast iron & titanium. Edge prep supplied and available in a wide range of sizes and corner radius styles, this balanced tool is a fine example of German engineering and American-made craftsmanship.
