Spiral Point Taps are designed for efficient tapping of thru holes and blind holes with adequate depth for chip accumulation at the bottom of the hole. The shearing action of the point provides freer cutting action and ejects the chips ahead of the tap, eliminating chip evacuation problems and chip damage to the threads. Shallower flutes also result in greater tap strength, allowing for higher cutting speeds.
3-5 Thread chamfer is the most common chamfer used for tapping applications in thru holes and blind holes with sufficient bottom clearance.
Recommended for all types of aluminum alloys.
CrN Coating especially recommended for high-silicon aluminum alloys.
