Is R8-ER16 balanced for high spindle speed?

Q: Is R8-ER16 balanced for high spindle speed?

Short answer: Balance grade is a property of the specific holder you buy, not of the code `R8-ER16`. Ask for the balance grade and the rpm it is rated at; **not published here**. A G2.5-rated holder and an unrated one share the same code. This is the most common mistake when substituting holders.
