#4-40 Dia. - Bottoming - GH5 - HSS Dia. - TiN - Thread Forming Tap Series/List #2105G MT3796382

Thread Formingtaps cold form rather than cut the threads. Advantages include no chips to dispose of, stronger higher quality threads, increased tapping speeds, longer tap life and reduced tap breakage. Recommended for a wide variety fo ductile materials. Lube Groovesprovide a path for lubication and act as vents to relieve pressure in blind hole tapping. Titanium Nitride (TiN) Coatingresults in a extremely hard surface with high lubicity for increased tool life, improved thread quality, reduced torque and increased tapping speeds tapping speeds for greater productivity.Country of OriginUSAWarning-Proposition 65- For Californian Users onlyWARNING: This product contains a chemical known to the State of California to cause cancer or Birth defects.
