💡 What is an ER11 collet set used for in precision milling setups?

A handy explanation for common questions:

• It securely clamps small-diameter tools (1/16" to 1/4", 1.59-6.35 mm) in CNC mills and small machines.
• Low TIR minimizes runout for cleaner, more accurate cuts and longer tool life.
• Using a coated PowerCOAT nut helps ensure repeatable torque and consistent grip.
