The Toolex HSS-E Piloted Counterbore (M8) is a precision cutting tool designed for clean, flat-bottom counterbores in metalwork. Built from HSS-E (high-speed steel with cobalt), this counterbore combines durability with heat resistance to deliver consistent results across a variety of materials.

• Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and long tool life
• Edge geometry: 180° cutting edge creates a flat-bottom counterbore for flush seating of screws
• Piloted design: centered pilot guides the cutter for accurate alignment and reduced wandering
• Size: Metric M8 counterbore, suitable for standard M8 fastening applications
• Applications: effective for counterboring steel, aluminum, cast iron, and other common metals
• Compatibility: compatible with standard drill chucks and drill presses when used with proper speeds and feeds

This tool helps you achieve precise screw recesses with repeatable depth, improving the finish and reliability of panel mounts, enclosures, and machinery assemblies. The cobalt-infused alloy maintains sharpness longer under load, while the piloted design ensures consistent, centered cuts across multiple parts, making it a dependable choice for both professional workshops and serious DIY projects.
