Innoform–Steel-M Forming Taps

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

For unsurpassed performance, Innoform–Steel-M taps feature innovative polygon geometry for low torque and longer life. A special powdered metal substrate and new TiN-66 coating with increased hardness reduces friction and extends tool life. And increased lubrication grooves in Innoform taps provide excellent process reliability. Innoform–Steel-M 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.

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.

  • hardness

    hardness

    Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.

  • nitriding

    nitriding

    Introducing nitrogen into the surface layer of a solid ferrous alloy. This is done to increase hardness, wear resistance and fatigue strength.

  • through-hole

    through-hole

    Hole or cavity cut in a solid shape that connects with other holes or extends all the way through the workpiece.
