The Toolex HSS-E Piloted Countersinks deliver precise, clean countersinking in metric sizes with a 90° angle, designed for professionals and serious DIYers who demand repeatable results. This M1 countersink pair pairs a robust, cobalt-enhanced high-speed steel body with a guided pilot for dependable starts and accurate depth control. Material: HSS-E (high-speed steel with cobalt) for superior wear resistance, strength, and heat tolerance in demanding materials. Angle: 90° countersink angle, offering a standard chamfer that suits a wide range of flat-head screws and assemblies. Piloted design: Built-in pilot provides precise alignment and stable entry, reducing wandering and ensuring consistent countersink depth. Size: Metric M1 sizing to align with common metric fasteners and hole preps. Cutting edges: Sharp, durable geometry that promotes efficient material removal and a clean, burr-free finish across metals, plastics, and wood. Applications: Ideal for creating flush screw seating in precision assemblies, enclosures, panels, and structural components where accuracy matters. This countersink is engineered for reliability in everyday machining and fabrication work. The piloted tip keeps the tool centered on the hole, helping you achieve consistent chamfers without guide drift. The cobalt-enhanced steel stands up to repeated use, delivering repeatable performance even as material hardness varies. Whether you’re finishing a metal panel or adding a clean edge to a wooden or plastic part, this Toolex countersink helps you reach professional-looking results with less effort and less rework.
