Description

Features

Back To Top
    • Reduce neck design and shorter thread length for increased coolant flow to the cutting edge, enhanced chip evacuation and reduced contact between tap and workpiece
    • For tapping a wide range of materials up to 28Rc hardness
    • Steam oxide over nitride increases wear resistance, reduces friction, reduces galling and chip welding, improves chip flow and increases tap lubricant retention
    • The spiral flutes draw the chips out of the hole
    • 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
