Some notes on using a reamer:

This reamer is manufactured from high speed steel, this is a very hard material.  This allows the tool to maintain a good cutting edge if used properly, however high speed steel is also very brittle.  Any cutting tool is susceptible to heat and chatter, either one will ruin your reamer in short order.  We recommend a maximum of 100 RPM, large amounts of quality cutting oil, and it is extremely important to keep the reamer straight and centered in the hole you are reaming.  Never run your reamer backwards (counter clockwise) this will dull the cutting edges.  If you follow the above guidelines, your reamer will give you years of service.
