The Toolex HSS-E Piloted Countersink Metric 90° in M1.6 size provides machinists and fabricators with a reliable tool for creating accurate, clean countersinks in small metric hole s. Its piloted design and cobalt-enhanced steel construction make it especially effective for precision work on metals where consistent results matter. Material: High-speed steel with cobalt (HSS-E) for improved heat resistance and edge retention during extended use on tougher materials. Angle: Standard 90° profile that matches common metric screw heads and fasteners for flush seating without gaps. Design: Piloted shank that maintains precise alignment and reduces chatter or wandering on entry. Size: M1.6 diameter suited for small-thread applications in electronics, instrumentation, and fine mechanical assemblies. This countersink helps eliminate misalignment and surface damage when preparing holes for screws, resulting in stronger joints and a professional finish. Machinists use it in drilling setups where accuracy on the first pass saves time and reduces scrap on delicate or high-value parts. Show more
