Description
The Toolex HSS-E Piloted Counterbore with a 180° cutting edge is a precision tool designed for creating clean, flat-bottom countersinks in metal and other machinable materials. Built for workshop professionals and serious hobbyists, it delivers consistent alignment, durable performance, and reliable results.
- Material: HSS‑E (high-speed steel with cobalt) for enhanced strength, wear resistance, and heat tolerance.
- Edge Geometry: 180° cutting edge creates a flat-bottom counterbore for uniform recess depth and a clean finish.
- Piloted Design: Integrated pilot guides the cutter for accurate alignment and stable entry, reducing wandering on small-diameter holes.
- Size: Metric size M1.0, aligned with standard metric holes and fastener applications.
- Applications: Suitable for precision counterbores in metals and other machinable materials, ideal for flush-fit fasteners and socket-head screw recesses.
This counterbore delivers repeatable, high-quality recesses with minimized misalignment and chatter. The cobalt-enhanced HSS construction helps sustain sharpness under higher cutting speeds and heat, extending tool life in busy workflows. The combination of a 180° flat-bottom edge and a piloted guide means you can achieve consistent depths and clean edges, even when starting from a small pilot hole. Whether you’re working with manual drilling equipment or a CNC setup, this tool provides reliability, precision, and a straightforward path to professional-looking results.
