In a single pass, these tools mill a precise, angled finish on the outside edge of pipe, tubes, and rods. Use them to deburr pipe and tube for butt welds or to shape rods and shafts for sliding into housings and holes. Faster and more precise than handheld scrapers, they work with screw machines, lathes, and drill presses to make reliable cuts, part after part. The six teeth distribute cutting force for a long service life. Staggered cutting edges reduce vibration for a clean cut and smooth chamfer. All are high-speed steel, a general purpose cutting-tool metal that works well on a variety of material. Attach to your machine with a shank (sold separately).
