<b>[Product Information]</b><br>
<ul>
<li>Left-hand spiral reamers are good for use in through holes (holes that extend all the way through a workpiece), as they push chips ahead of the tool and into the hole</li>
<li>Spiral reamers are recommended for reaming holes with interruptions, as they prevent damage to the workpiece edge and tool</li>
<li>Round shank tools are cylindrical and should be held in a good-quality toolholder in order to prevent the reamer from slipping in high torque applications, which can cause tool freeze, loss of accuracy, and tool damage</li>
<li>Uncoated (bright) tools have no finish or coating. They are a good choice for general purpose applications</li>
<li>High-speed steel is a common general purpose steel for cutting tools, is compatible with a variety of materials, and tends to be lower in price than cobalt steel or carbide</li>
</ul>
