This is a new Sandvik Coromant CoroTap 100 spiral flute machine tap, part number T100-KM105AA-M12, catalog order code 3RT0721470, for cutting M12 threads to a 6HX tolerance class per DIN/ANSI standards. The CoroTap 100 series is designed for through-hole tapping in steel, cast iron, and similar short-chipping materials, using a spiral flute geometry to evacuate chips upward out of the hole during the cut. The D210 designation indicates an overall length of 210 mm, and the KM105AA shank is a cylindrical shank with internal coolant supply through the tap body, enabling high-pressure through-coolant delivery directly to the cutting zone for improved tool life and chip control at elevated spindle speeds in CNC machining centers. The tap features a black oxide/steam-oxide surface treatment visible in the photos, consistent with Sandvik's standard finish for this series, which reduces friction and provides corrosion resistance during storage and use.
