The Dormer A520 is a 27/64 in (10.72 mm) HSS stub-length (screw-machine) drill bit conforming to DIN 1897, manufactured in England and featuring Dormer's ADX (Advanced) TiN (Titanium Nitride) coating — a gold-colored physical vapor deposition finish that increases surface hardness, reduces friction, and extends tool life compared to uncoated HSS. The stub/screw-machine flute length provides enhanced rigidity and reduced deflection relative to jobber-length equivalents, making this drill particularly suited for CNC machining centers, drill presses, and automatic screw machines drilling steel, cast iron, aluminum, and other general-purpose metals. New in original Dormer red plastic case with yellow label confirming HSS ADX Stub Drill, DIN 1897, England, FA00 date code, and UPC 7320760171455. The straight round shank is compatible with standard drill chucks and collet holders accepting 27/64 in shanks.
