The Toolex HSS-E Piloted Counterbore Metric 180° - M3 delivers accurate flat-bottom recesses for M3 fasteners in metal components. Machinists and fabricators rely on it for clean, repeatable results in precision assemblies.

• Material: High-speed steel with cobalt (HSS-E) provides strength and heat resistance for extended cutting in tough alloys.
• Cutting Edge: 180° angle produces a true flat bottom that seats screws flush without gaps.
• Design: Integrated pilot ensures precise alignment and prevents tool walk during entry.
• Size: Metric M3 configuration matches standard fastener diameters for consistent fit.

By creating uniform counterbores in one pass, this tool reduces secondary finishing steps and helps maintain tight tolerances on jigs, fixtures, and machine parts. Its stable pilot action supports consistent hole quality even on curved or thin stock.
