In part 11 we read that the accuracy and consistency of hole sizes made by a tungsten carbide reamer is affected by many variables in reaming process, such as reamer design and materials involved, and coolant fluid is recommended since it helps repeatedly maintain the hole size to be as close as possible to reamer diameter.And here we learn about the longevity of a tungsten carbide reamer and the equipments used for it .

Surface finish and longevity

When properly designed and used, reamers can experience an extended service life of up to 30,000 holes. A properly controlled process is also capable of maintaining a consistent size down the entire length of the hole while minimizing the hour-glass effect. Reamed holes may typically have a surface finish of 10 to 25 µin. Ra.

Setup and equipment

Generally, reaming is done using a drill press. However, lathes, machining centers and similar machines can be used as well. The work piece is firmly held in place by either a vise, chuck or fixture while the reamer advances.
