Already available for use on difficult-to-cut materials such as stainless steel, titanium, Inconel and other high-temperature alloys, StarMill has been extended with the arrival of the SED4 UL range of 4-flute extra-reach end mills. The UL extension introduces end mills in 3, 4, 6, 8, 10 and 12 mm diameters with an overall reach from 63 to 92 mm, depending upon the chosen diameter. With a flute length from 10 to 40 mm, this addition to the SED line-up enables manufacturers to access small cavities and difficult-to-reach surfaces.

In addition to the SED4 UL line, TaeguTec has also introduced a complete line of SED4 UR end mills with a corner radius for enhanced tool life and machining performance. The SED4 UL range is available in diameters from 2 to 16 mm with each diameter offering the customer a selection of corner radii. Although the 4 mm diameter tool offers users the choice of a 0.1, 0.2 or 0.5 mm radius, the largest 16 mm end mill is available with a 0.5, 1, 2 or 3 mm corner radius.

All ranges within the SED StarMill portfolio incorporate unequal flute spacing and a high helix that combine to reduce harmonic effects and vibration during high-speed machining. Furthermore, the polished high-helix flutes improve chip evacuation, while the TT5515 grade coating prolongs tool life, even under challenging machining parameters, says TaeguTec.
