The Toolex HSS-E Piloted Counterbore with a 180° cutting edge is a precision tool designed for creating clean, flush-bottom counterbores in a wide range of materials. Built for professionals who demand consistent depth and alignment, this counterbore delivers reliable performance in metalworking and fabrication tasks.

• Material: HSS-E (high-speed steel with cobalt) for superior strength, wear resistance, and heat tolerance
• Edge geometry: 180° flat-bottom counterbore to produce true, square recesses
• Piloted design: Integrated pilot guides the cutter for accurate starting alignment and stable cutting
• Size: Metric M1.2 pilot diameter ensures precise engagement with standard holes
• Material compatibility: Effective across a broad range of workpieces, including steel, aluminum, and certain plastics

With its piloted guidance and cobalt-enhanced steel, this counterbore minimizes wandering and delivers consistent recess depth and finish. The 180° bottom provides a true, flush seating for bolts and fasteners, reducing additional finishing steps. Ideal for mechanical assemblies, cabinetry hardware installation, and general metalworking projects where precise, repeatable counterbores matter.
