<b>[Product Information]</b><br>
<ul>
<li>Three flutes provide better chip-carrying capacity than four flutes and a finer finish than two, reducing the need for a second finishing cut in some applications</li>
<li>Titanium nitride (TiN) is a general-purpose coating that combines high-temperature resistance and increased hardness compared to uncoated end mills</li>
<li>High-speed steel is compatible with a variety of materials</li>
<li>Square nose end mills (also called square end) create sharp, unrounded cuts</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>
