The Toolex HSS-E Piloted Countersinks are precision countersink bits designed to create clean, flush seating for screw heads across a variety of materials. Built for professionals and serious hobbyists, they deliver repeatable accuracy and long-lasting performance. Angle: 90° countersink angle for standard flush seating Pilot: Piloted design provides precise alignment and reduces wandering during entry Material: HSS‑E (high‑speed steel with cobalt) for enhanced hardness, wear resistance, and heat tolerance Size: Metric M1.2 pilot size Applications: Suitable for countersinking holes in metal, wood, and certain plastics with consistent results With the cobalt-enhanced HSS, this countersink resists wear and maintains its sharp edge longer under demanding cutting conditions. The built-in pilot ensures your first hole starts true, enabling clean deburring and a precise seating depth every time. The standard 90° angle supports a professional, flush finish for a wide range of screw head types, making it a reliable choice for cabinetry, metal fabrication, and general joinery.
