The Hoffmann Group, a leading system partner for quality tools, has expanded its GARANT Master Tap product range to include additional high-performance taps for reliable thread tapping in stainless and high-alloy steels. The GARANT Master Tap INOX tap 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 (BSPP). These new tools are available now from our eShop www.hoffmann-group.com and can be ordered using the 2020/2021 catalog which launched August 1.
The GARANT Master Tap INOX is suitable for producing through and blind hole threads with a tolerance of 6GX. As with all tools from the GARANT Master Tap product range, it provides top process reliability, performance capability, and a long working life because a special 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 specially designed to 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 HSS-E-PM tool material and low-friction TiAIN multi-layer anti-friction layer 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 achievesprecise results, even in ductile copper alloys, without any axial overcutting and makes frequent tool changes redundant.
The Hoffmann Group debuted the GARANT Master product range in 2015 to make high-performance cutting with particularly powerful and reliable tools even more productive. The product range has been systematically expanded since then and now offers state-of-the-art high-performance tools for every application.

- alloys
alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- copper alloys
copper alloys
Copper containing specified quantities of alloying elements added to obtain the necessary mechanical and physical properties. The most common copper alloys are divided into six groups, and each group contains one of the following major alloying elements: brasses—major alloying element is zinc; phosphor bronzes—major alloying element is tin; aluminum bronzes—major alloying element is aluminum; silicon bronzes—major alloying element is silicon; copper-nickels and nickel-silvers—major alloying element is nickel; and dilute-copper or high-copper alloys, which contain small amounts of various elements such as beryllium, cadmium, chromium or iron.
- flutes
flutes
Grooves and spaces in the body of a tool that permit chip removal from, and cutting-fluid application to, the point of cut.
- swarf
swarf
Metal fines and grinding wheel particles generated during grinding.
- tap
tap
Cylindrical tool that cuts internal threads and has flutes to remove chips and carry tapping fluid to the point of cut. Normally used on a drill press or tapping machine but also may be operated manually. See tapping.
- tapping
tapping
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
- tolerance
tolerance
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
