TiNox-Cut is a new series of end mills from Emuge Corp. that the company says were developed to provide exceptional tool life when machining challenging materials.

They offer a dependable cutting solution for nickel alloys like Inconel and Stellite, all grades of titanium, and tough stainless steels like Super Duplex - materials used extensively in the aerospace, power generation, medical, chemical and food industries, among others.

"The demand for parts and components machined from these materials is on the rise, but the same special properties, like high heat, chemical and abrasion resistance, that make these materials desirable for use in extreme service applications, also make them difficult to machine,” says Stephen Jean, Emuge's milling products manager. "Typically, these materials burn up cutting tools. Now, with TiNox-Cut End Mills, Emuge has something to combat this.”

The new end mills feature a high heat-resistant, lubricious coating and an optimized cutting edge design. This provides long tool life by minimizing friction and efficiently evacuating chips, which is especially important in tough, long-chipping materials. In addition, the tools are made from an extra-tough carbide grade to maximize wear resistance.

For maximum effective cutting lengths, the end mills feature reduced neck diameters.  Offering superior machining repeatability and safety, they combine a tight, h5 shank tolerance with a specially roughened surface finish to maximize tool holder clamping potential.

They're well suited for both roughing and finishing operations and consist of three designs:  two four-flute variations for both roughing and finishing, and a five-flute extra long finishing tool. 

The cutting tools are available with flat ends or with a selection of corner radii. For even more efficient chip evacuation, TiNox four-flute end mills are available with internal coolant / lubricant capability. The roughing/finishing versions are available with a serrated profile for effective chip breaking during roughing operations.

The five-flute finishing end mills are also available with various corner radii, and feature length-to-cutting diameter ratios of three times D and four times D. The five-flute design offers added stability and minimal deflection in long reach applications. 

The end mills range in diameter from 6 mm – 20 mm, depending on the design.
