Introducing the Toolex HSS-E Piloted Counterbore (180°) with an M12 shank—a precision tool designed for professionals and serious hobbyists who need repeatable, clean counterbores. Built with cobalt-enhanced HSS-E, it delivers strong performance, excellent heat resistance, and long tool life for demanding machining tasks.

• Material: HSS-E (high-speed steel with cobalt) for enhanced strength, wear resistance, and heat tolerance.
• Cutting edge: 180° geometry creates a flat-bottom counterbore for accurate, uniform recesses.
• Piloted design: integrated guide ensures precise alignment and stable cutting during operation.
• Shank size: M12 metric shank compatible with common drill chucks and tool holders.
• Material compatibility: suitable for counterboring a range of materials, delivering consistent depth and finish.

This counterbore helps you achieve flush fastener seating with minimal rework. The piloted design reduces wandering, while the durable HSS-E construction stands up to repeated use in various materials. Ideal for cabinetry, metal fabrication, appliance installation, and other precision counterboring tasks where accuracy and reliability matter.
