1/4" - 20 2-Flute, H5 Series/List # 2093S Spiral Flute Tap MT3360784

HPT†- High Performance Tap - Aluminum Recommended for all types of aluminum alloys. CrN coating especially recommended for high-silicon aluminum alloys. Spiral Flute Tapsare designed to lift the chips out of the hole in blind hole tapping, eliminating chip evacuation problems which can result in damaged threads and broken taps. They will also bridge openings, keyways and other interruptions in the tapped hole. Semi-Interrupted Thread(3-Flute taps only) 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 greater number of teeth. CNC Reduced Neck Designenhances chip evacuation and cutting fluid flow to the cutting teeth for reduced friction, heat and galling. Also reduces contact between the tap the work piece.
