Description

The Toolex HSS-E Countersink features a 3-flute design and a 90° angle for precise, clean countersinks. Crafted from high-speed steel with cobalt (HSS‑E), it’s built for durability and long-lasting cutting performance.

  • Diameter: 6.3 mm
  • Material: HSS‑E (high-speed steel with cobalt) for enhanced hardness and wear resistance
  • Flutes: 3-flute design for efficient material removal and reduced clogging
  • Angle: 90° countersink angle for a universal chamfer usable across many projects
  • Coating: Uncoated surface that allows direct contact with the workpiece and optimal chip evacuation
  • Applications: Versatile for a wide range of applications and materials, delivering consistent, reliable results

With a precise 90° chamfer, it yields flush screw seating and clean edges, reducing burrs and post-processing. The cobalt-enhanced HSS construction resists wear in demanding materials, extending tool life, while the uncoated finish supports immediate use and efficient chip evacuation for smooth operation.
