• Spiral point taps are designed for machine tapping in through holes in a wide variety of materials
• The point ejects the chips ahead of the tap, eliminating chip disposal problems and thread damage
• Shallower flutes also result in greater tap core strength allowing for higher cutting speeds
• Plug style (3 to 5 thread chamfer) is the most common chamfer used for tapping applications in through holes and blind holes with sufficient bottom clearance
• 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 workpiece
• Steam oxide over nitride features a hard abrasive resistant nitride base for enhanced tool life in abrasive materials including cast iron
• Steam oxide surface treatment reduces friction, loading and galling, helps retain cutting fluids, improves thread quality and extends tool life
