Onyx spiral point tap, general purpose, series: 2101, imperial, UNC, 3/8-16, plug chamfer, 3 flutes, HSS, black steam oxide over nitride, right hand cutting, 3/4 in thread length, 2-15/16 in overall length, materials up to 28RC hardness material application, H3 thread limit, yes through coolant.
Features
- 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
