The Toolex HSS-E Countersink is a precision drilling accessory designed for metalworking that demands clean, repeatable countersinks. With a 45° single-flute design and cobalt-enhanced HSS, it delivers reliable performance for chamfers and deburring tasks.

  • Material: HSS-E (high-speed steel with cobalt) for enhanced durability and heat resistance
  • Angle: 45° countersink for shallow chamfers and precise edge finishing
  • Flute design: Single flute to improve chip evacuation, reducing clogging and heat buildup
  • Size: Length 25mm for versatile reach in various applications
  • Application: Creates clean countersinks and smooth deburring on metal surfaces
  • Precision: Engineered to maintain a consistent countersink diameter and edge quality

With the Toolex HSS-E Countersink, you can achieve professional, burr-free edges and uniform chamfers that improve the fit and finish of assembled parts. The cobalt-enriched HSS construction resists wear and heat during cutting, extending tool life even with repeated use. The single-flute design minimizes clogging for smooth cutting across materials, and the 25mm reach provides flexibility for shallow to mid-depth countersinking tasks.
