Tackle tough drilling jobs with this professional-grade Norseman 20mm Silver & Deming drill bit! Made right here in the USA with HI-Moly M7 steel, this bit is built to drill through hard materials like steel, cast iron, and other metals without dulling quickly. The Silver & Deming style means it has a 1/2\ reduced shank that fits standard chucks, but the cutting diameter is a full 20mm (about 0.787 inches). Perfect for machinists, metalworkers, automotive shops, or serious DIYers who need precision and durability. Model 25520 comes brand new in its original packaging, ready to go to work. Whether you're enlarging holes, drilling through brackets, working on machinery, or doing fabrication projects, this bit delivers clean cuts and long life. Norseman is known for quality, and this bit shows why. Keep it in your toolbox for when you need to drill big, accurate holes in tough stuff. A worthy investment for anyone who works with metal regularly!
