Red ring taps for tough materials Why a 15° helix vs a 40° helix?
When tapping high tensile steels or tougher alloys, using a tap with a lower helix Tapping of high tensile materials typically produces high amounts of torque on
angle can sometimes improve tool life. a tool. It is advantageous to note that when the needed thread depth is 1.5 x
diameter or less - a 15° helix tool will withstand higher torque than a 40° helix
High tensile and some high alloy steels can be difficult to tap. Guhring’s red ring while still pulling chips from the hole efficiently.
offering provides you with tools that are designed with these materials in mind.
Both a thicker core diameter and a lower rake angle add strength for these
manufacturing applications.
