The Toolex HSS-E Piloted Counterbore (180°) is a precision tool for machinists, fabricators, and DIY enthusiasts who need clean, flat-bottom counterbores in metric sizes. Made from HSS-E with cobalt, it delivers strength and heat resistance for reliable performance on metal and plastic work.

• Material: HSS-E (high-speed steel with cobalt) for enhanced strength and wear resistance at high speeds.
• Edge geometry: 180° cutting edge creates a true flat-bottom counterbore for uniform recess depths.
• Piloted design: built-in guide ensures accurate alignment and minimizes drift during drilling.
• Size: Metric M2.6 countersinks for precise screw recesses in metric fasteners.
• Applications: suitable for countersinking in a range of materials, including metals and plastics, delivering clean, repeatable results.

With the Toolex HSS-E Piloted Counterbore, you’ll achieve flush seating for fasteners, reduce rework, and maintain a consistent finish across workpieces. The cobalt-enhanced HSS core stands up to heat and wear, while the piloted tip and flat-bottom geometry provide reliable depth control and alignment for repeatable, professional results in everyday machining and fabrication tasks.
