Hoffman Group Expands Garant Master Tap Line

The Hoffmann Group has expanded its Garant Master Tap product range to include additional thread taps in stainless and high-alloy steels. The Garant Master Tap Inox is now available for thread diameters from M1.6 to M24 and with longer lengths for increased reach. It is also available for UNC and UNF inch diameters from No. 2 to 1" standards in addition to the thread standards M, MF, and G (British standard pipe). 

The Garant Master Tap Inox is suitable for producing through and blind hole threads with a tolerance of 6 GX. It is said to provide process reliability, performance capability and a long working life due to its cutting edge geometry, which provides evenly turned chips ejected in a targeted way. The backs of the teeth shear off the chips, polish the chip roots and prevent loose or twisted swarf from forming.

The cutting edges of the Garant Master Tap Inox have also been rounded off to ensure reliable thread machining in stainless and high-alloy steels. As a result, the teeth resist fracture and the tool wears evenly. A wear-resistant powder metallurgy high strength, cobalt-alloy steel (HSS-E-PM) tool material and low-friction TiAlN layer protect against premature wear.

For users that also want to machine different steels, aluminum, brass and cast iron, there is the general-purpose Garant Master Tap, designed to achieve precise results, even in ductile copper alloys, without any axial overcutting and to make frequent tool changes redundant.
