The Koronet SUPREME 900X<\/strong> machine tap<\/a> is a premium tool designed for precise internal threading in structural steels, alloy steels and materials that require a stable, repeatable cutting process. Made of high-grade high-speed HSSE<\/strong> steel and equipped with an AlCrN<\/strong> coating, it provides increased wear resistance and high tool life compared to traditional TiN-coated taps. <\/p>\n

\u2022 HSSE steel \u2013 high resistance and stability of operation<\/strong><\/h3>\n

The tap is made of high-speed HSSE steel, combining good impact strength with increased resistance to torsional loads. This ensures that the tool works stably even in materials with greater strength. <\/p>\n

\u2022 Premium coating \u2013 SUPREME 900X AlCrN<\/strong><\/h3>\n

The modern AlCrN-based coating is characterized by:
\u2013 high abrasion resistance,
\u2013 increased thermal stability,
\u2013 limiting chip adhesion,
\u2013 better tool life compared to TiN\/TiCN coatings.<\/p>\n

This allows for safe operation at higher parameters and in more difficult steel grades.<\/p>\n

\u2022 Straight geometry \u2013 for through-holes<\/strong><\/h3>\n

Straight grooves provide linear guidance and efficient chip output in the opposite direction to the tool rotation, which is optimal for threading through holes.<\/p>\n

\u2022 DIN 371 standard \u2013 reinforced handle<\/strong><\/h3>\n

The tap has a reinforced handle typical of DIN 371, which increases its resistance to bending and improves the stability of handling during operation.<\/p>\n

\u2022 Version B \u2013 4-5 chamfer turns<\/strong><\/h3>\n

The B-type cut allows easy tool insertion and ensures safe thread formation in through holes. It is a universal and most commonly used geometry in workshop and industrial production. <\/p>\n

The SUPREME 900X tap is designed for processing:<\/strong>
\u2022 unalloyed and structural steels,
\u2022 alloyed and heat-treated steels,
\u2022 steel with increased strength,
\u2022 materials that tend to grow.<\/p>\n

Recommended for both CNC machine tools and precision conventional machine heads \u2013 wherever repeatability, stability and long tool life are important.<\/p>\n","protected":false},"excerpt":{"rendered":"
