For holes over 1/4, the three percent works well in holding size for reams within .0002 to .0005, which often becomes a tool sharpening issue at ...

    Getting reaming right | Cutting Tool Engineering

    01.06.2010· When too much stock remains for reaming after drilling, end users have the option of reaming twice. Monster Tool's Lynberg suggests first applying a smaller reamer followed by a reamer of the required size. "Drilling to open up a hole usually causes drill failure due to unequal and uneven stress along the drill's cutting edge and is not recommended," he said. Lynberg added that plunge ...
