The Hoffmann Group (Knoxville, TN) has systematically updated the Garant Master product line since introducing the cutting tools in 2015. Designed to produce through and blind hole threads in stainless and high-alloy steels with a tolerance of 6GX, the Garant Master Tap INOX tap is available for thread diameters from M1.6 to M24 and with longer lengths for increased reach. It’s also available for UNC and UNF inch diameters from No. 2 to 1-inch standards in addition to the thread standards M, MF, and G (BSPP).
Like the rest of the Garant Master Tap product range, the INOX’s cutting edge geometry provides evenly turned chips that are ejected in a targeted way due to the optimized flutes. The backs of the teeth are designed to shear off the chips, polish the chip roots, and prevent loose or twisted swarf from forming. Rounded cutting edges help the teeth resist fracture, and the tool wears evenly. A wear-resistant HSS-E-PM tool material and multiple layers of low-friction TiAIN protect against premature wear.
Thanks to the expanded product range, there are now even more tools available to professional users for reliable thread machining in stainless and acid-resistant steels. Users that also often want to machine materials such as different steels, aluminum, brass, and cast iron can alternatively make use of the Garant Master Tap general-purpose tap. It achieves precise results, even in ductile copper alloys, without any axial overcutting and makes frequent tool changes redundant.
