Rigid Tapping--Sometimes You Need A Little Float

One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.'

Another Way To Square—Or Is It Perpendicular?—It Up

There are a number of tools available for shop personnel to evaluate the right angle relationship between two surfaces. The basic machinist square has a number of variations, the most common being the hardened steel square used to check right angles and set up milling and drilling machines.
