<b>[Product Information]</b><br>
<ul>
<li>Four flutes produce a better finish than fewer flutes</li>
<li>Aluminum titanium nitride (AlTiN) coating lubricates the end mill for high-temperature stability and abrasion resistance, offering better heat resistance than TiN, TiAlN, and TiCN coatings</li>
<li>Carbide can run at higher speeds than high-speed steel, resisting abrasion and high cutting temperatures</li>
<li>Ball nose end mills (also called ball end) create contoured surfaces</li>
<li>Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling</li>
</ul>
