HPT†- High Performance Tap - Cast Iron Recommended for all types of gray, ductile and malleable cast iron. Straight Flute Steam Oxide Over Nitride Finishfeatures a hard abrasion resistantNitrided Basefor enchanced tool life in abrasive materials including cast iron.Steam Oxidesurface treatment helps toughen the nitride base, reduces friction, loading and galling, helps retain cutting fluids, improves thread† qualtiy and extends tool life. 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.
