Precision 0.5 mm tungsten steel spiral drill for metalworking — suitable for both milling and drilling. Built to deliver consistent, tiny holes where accuracy and durability matter. Key benefits Precision: 0.5 mm diameter for accurate, repeatable holes in thin metal work. Durability: hard, wear-resistant tungsten steel core extends tool life under heavy use, reducing tool changes and downtime. Cleaner operation: spiral flute design ejects chips efficiently for smoother cutting and fewer clogs or breakages. Versatile: suitable for both drilling and light milling tasks in small-scale metalwork. Ready to use: single-piece item supplied ready for immediate use. Important attributes Material: tungsten steel with a hard, wear-resistant core. Design: spiral flute for efficient chip removal and stable cutting. Size: 0.5 mm diameter. Other small diameters from 0.15 mm to 0.6 mm available on request. Compatibility: fits most electric drills and standard chucks. Practical applications (examples) Drilling tiny holes in stainless steel sheets or small brackets for fittings and fasteners. Creating precise pilot holes in aluminum enclosures or brass prototypes before finishing or tapping. Fine metalworking tasks such as jewelry making and scale model building where small, accurate holes are required. What it solves Produces consistent, small-diameter holes where larger drills cannot achieve the needed precision. Reduces tool wear and interruptions thanks to a hard core and efficient chip evacuation. Works with common drill chucks so you can use it with existing workshop or hobby tools. Order details Single-piece item, ready to use. Request other diameters (0.15–0.6 mm) if you need a different small size.
