Seco Tool’s Niagara Cutter subsidiary has added two new six-flute tools to its line of multi-flute end mills for high-speed milling and peel milling applications. Able to take larger radial depths of cut than the seven- and nine-flute tools in the line, the S638 and S638R are said to produce higher metal removal rates, reduced cycle times and increased throughput.

The end mills feature an aluminum titanium nitride coating, enabling them to achieve long, predictable tool life in milling applications that involve high temperatures and abrasive workpiece materials, such as titanium and pH stainless steels. The eccentric OD relief provides a stronger cutting edge, further adding to increased tool life. Variable indexing also reduces harmonics for smooth cutting and high surface finishes.

The end mills are available in diameters ranging from 0.375" to 1" with as much as 2.5 times the diameter of flute length.
