Spiral Point

High Speed Steel Spiral Point Taps/ Straight Flute - Used for hand and machine tapping in both thru or blind holes in a wide variety of materials. Spiral point taps have the same general physical dimensions as standard hand taps. The point ejects the chip ahead of the tap, eliminating disposal problems and thread damage. Ideal for production tapping of through holes. Typically, this type of tap has a shallower flute passage than conventional taps. This gives the spiral point tap more cross-sectional area, which means greater strength, allows higher tapping speeds, and requires less power to drive. NOTE: When tapping in blind holes, clearance at bottom of hole for chip disposal is critical. If You do not have space at bottom of hole, chip{s} will pack and may cause the tap to break.
