Reaming

 

a method of machining holes by cutting (after drilling and countersink reaming) with a multiblade cutting tool called a reamer. As a result of rough reaming, an allowance of not more than 0.5 mm in diameter is removed, providing surface roughness of class 7 and a precision of class 3. In finish reaming, an allowance of not more than 0.2 mm is removed, providing a surface roughness up to class 9 and a precision up to class 2.

Reaming through a cylinder's chambers will nearly always leave those chambers with sharp edges, so as a final step on any reaming job, you should carefully de-burr both the front and rear edges of the chambers.
Facing the prospect of replacing hundreds of thousands of feet of old AC pipe, project owners and contractors are faced with what they must do to comply with environmental regulations to properly dispose of old AC pipe removed from the ground, pieces of broken pipe removed in slurry during pipe reaming operations, and whether it is permissible to leave broken AC pipe segments in the ground after pipebursting procedures.
The newest motors added to the product line have increased bearing capacity to allow forward and backward reaming with a motor instead of transmitting the torque through the drill pipe.
