A deeper look at precision toolholders
Although toolholders are known to be critical components in the precision machining process, the unique details that differentiate a "standard" toolholder from one that is designed for more precise, high speed work can be subtle. Like the parts they are used to create, precision toolholders are machined to exacting tolerances to create the optimum fit within the spindle, concentricity and balance. The more precise the work, the more these factors come into play.
