It’s ideal for professionals and serious DIYers who demand consistent results and long-lasting performance. Material: HSS-E (high-speed steel with cobalt) delivers enhanced hardness, wear resistance, and heat tolerance for durable, long-lasting cutting edges. Size: Metric M1.8 with a 90° countersink angle — a standard profile that suits a wide variety of screw heads and finishing needs. Piloted Design: Integrated center pilot ensures precise alignment and stable cutting, minimizing wandering for repeatable depth control. Angle: 90° countersink angle provides a universal seating profile compatible with common flat-head and binding-head screw applications. Applications: Suitable for a broad range of materials, including metal, wood, and plastics, when you need crisp, professional recesses. This countersink is built to reduce rework and deliver a professional finish. The HSS-E composition handles higher heat and tougher materials, while the piloted guidance keeps every hole centered and consistent. Ideal for cabinetry, metal fabrication, furniture assembly, and general joinery where precise, flush seating is essential.
