Spiral Flute Taps are designed to lift chips out of the hole in tapping blind holes, removing chips that can damage threads and break taps. They can also bridge cross-holes, keyways and other interruptions in the holes.
for a wide range of materials up to 28Rc
Semi-Bottoming Style (2-3 thread chamfer) allows threading close to the bottom of blind holes but cuts more efficiently than standard bottoming taps due to a slightly longer chamfer which distributes the cutting load over a greater number of teeth.
CNC Reduced Neck Design enhances chip evacuation and cutting fluid flow to the cutting teeth for reduced friction, heat and galling. Also reduces contact between the tap and the work piece.
