5/16 - 18 Dia. - GH4 - 4 FL - Premium HSS - TiAlN - Bottoming Thread Forming Tap Series/List #2106T MT4261724

HPT†- High Performance Tap - Thread Froming - DIN Length Recommended for a wide variety of ductile materials up to 28Rc hardness. Thread Formingtaps cold form rather than cut the threads. Advantages include no chips to dispose of, stronger high qaulity threads, increased tapping speeds, longer tap life and reduced tap breakage. DIN Length -longer than standard USCTI length - provides extra reach in tapping applications. ANSI Shank- made to standard Anmerican dimensions - fits standard tap holders. Lube Groovesprovide a path for lubrication and act as vents to relieve pressure in blind hole tapping. Plug†Style(4 threads tapered) for through holes and blind holes with adequate depth. The longe taper lead is easier starting, requires less torque, produces less burr above teh mouth of the tapped hole and increase tool life. Bottoming Style(2 threads tapered) for blind holes. 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.
