The Hoffmann Group has added the MasterTap high-performance tap to its Garant Master tool series. This product is the result of a development concept for the design of universal taps, achieving high process reliability and efficiency in a wider range of materials including steel, stainless steel, aluminum, brass and cast iron.

The key to MasterTap’s versatility is its effective chip removal enabled by a new cutting edge geometry as well as optimized flutes. These features are said to consistently eliminate winding chips and loose swarf.

When reversing in blind-hole machining, the Garant MasterTap promotes reliability by shearing off chips and smoothing the chip roots with a specially-designed tooth back. The tool excels in particular when machining high-strength steel materials thanks to its rounded cutting edges, according to the company. This rounding also insures defined and continuous wear behavior without breakouts and thus a longer service life.

The tool’s HSS-E-PM cutting material and AlTiX coating help it to achieve high performance and longevity. The ultra-smooth coating protects against premature wear and enables high cutting speeds, even in aluminum-wrought alloys, because the low friction values ​​prevent material sticking and thread corrosion. Thanks to its special guide thread, the tool achieves precise results without axial slicing even in ductile copper alloys.
