Toolex HSS-E Countersink - 3 Flute 90° Uncoated - 9mm

The Toolex HSS-E Countersink is a precision tool designed to create clean, accurately sized countersinks with a 90° chamfer. Crafted from cobalt-enhanced high-speed steel, it delivers reliable performance and long-lasting durability for demanding drilling and finishing tasks.

• Diameter: 9 mm
• Angle: 90° countersink angle for versatile seating options
• Flutes: 3-flute design for efficient material removal and reduced clogging
• Material: HSS-E (high-speed steel with cobalt) for improved hardness and wear resistance
• Coating: Uncoated surface ensures direct workpiece contact and efficient chip evacuation
• Applications: Suitable for a wide range of materials and finishing tasks requiring precise countersinks

The 3-flute geometry optimizes chip flow, minimizes chatter, and produces smooth, flush countersinks that seat fasteners neatly. The cobalt-enhanced HSS core stands up to repeated drilling in harder materials, extending tool life and reducing downtime. Because the countersink is uncoated, it provides direct contact with the workpiece for consistent cutting performance and easy maintenance. Whether you’re preparing soft metals, dense plastics, or versatile composites, this countersink helps you achieve professional results with clean edges and accurate depth control.
