<b>[Product Information]</b><br>
<ul>
<li>The combination of Stabilizer flute geometry, carbide substrate, and AlCrN coating make this end mill suitable for use on hard materials such as carbon and tool steels, steel alloys, and cast iron</li>
<li>Stabilizer flute design uses unequal spacing and variable helix angles to minimize tool vibration and remove up to three times more chips per minute than conventional carbide end mills</li>
<li>Aluminum chromium nitride (AlCrN) coating provides good hardness and better resistance to chemical breakdown in high-heat applications than TiAlN, TiCN, and TiN coatings</li>
<li>Four flutes produce a better finish than fewer flutes</li>
<li>Corner radius end mills have cutting edges with rounded corners to reduce chipping and provide longer tool life</li>
