ER32 → The collet size/type (clamping range ~2mm to 20mm, used with ER32 collet chucks).
-
AA → Accuracy grade (AA = High Precision, usually better runout than standard A grade).
-
0.008 → Indicates runout tolerance (0.008 mm = 8 microns). This is very precise, used for high-speed machining, milling, drilling, tapping, and toolholding.
These are High Precision ER32 Collets (AA grade, 0.008 mm runout), designed for CNC machines, tool holders, and milling applications where accuracy and repeatability are critical.
