SANDVIK Sandvik - 5/16" Unc Blue Spiral Flute Tap

Sandvik T300-XM100DE-5/16 C145 – HSS-E Blue Spiral Flute Tap (5/16” UNC, C145 Grade)

The Sandvik T300-XM100DE-5/16 C145 is a premium spiral flute machine tap engineered for high-performance threading of 5/16” UNC threads. Specifically designed for use in rigid CNC and conventional machines, this tap delivers exceptional results in blind-hole applications, where its spiral flute design efficiently lifts chips upward and out of the cutting zone, ensuring clean threads and uninterrupted operation.

Manufactured from high-speed steel with cobalt (HSS-E) and enhanced with Sandvik’s C145 blue coating, the tap provides outstanding wear resistance, reduced friction, and superior heat resistance. Its optimized flute geometry and material combination contribute to extended tool life, consistent performance, and reliable threading in tough materials such as stainless steels and alloy steels.
