Roll Form Taps Ideal For Medium Strength Steels

Emuge Corp. introduces Innoform–Steel-M, a line of HSSE-PM taps designed for forming threads with improved surface quality, while increasing static and dynamic thread strength, in medium strength steels up to 44 HRC.

The taps feature innovative polygon geometry for low torque and longer life. A special powdered metal substrate and TiN-66 coating with increased hardness reduces friction and extends tool life. Increased lubrication grooves provide excellent process reliability. The taps are recommended for forming cold-extension steels; cementation steels; castings; heat-treatable, nitriding and cold work steels; and high-alloyed and hot work steels.

The taps are available in styles for blind or through hole applications in lead taper forms C/2-3 and E/1.5-2 threads, and in solid or coolant-through capability, over 80 models in total. Inch taps are available in UNC and UNF thread sizes, feature 2BX class of fit and DIN length and ANSI shanks, while metric taps feature coarse and fine thread sizes with 6HX class of fit, and DIN length and DIN shanks.
