10-32 GH3 2 FLUTE SPIRAL FLUTE BOTTOM TAP HPT High Performance Tap Overall Length 2-3/8" Thread Length 23/64" Neck Length 17/32" For Use With Aluminum Bright Finish Powder Metallurgy High Speed Steel Spiral Flute Taps are 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. 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 Design enhances 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.
