DIYers and craftspeople, these uxcell diamond mounted points are super handy for detailed grinding and shaping work! Each pack comes with two tapered nose bits that feature diamond-coated heads for effective material removal. The 8mm diameter head with 13mm length gives you plenty of working surface, while the 3mm shank fits most standard electronic grinders, hanging mills, and hand electric drills. The total length of 45mm makes them easy to handle and control during precision work. Made from metal with diamond coating, these silver-toned bits are perfect for sculpting, dressing, precision grinding, and internal grinding on tough materials like carbide, ceramic, glass, precious stones, and various alloys. The tapered shape allows you to get into tight spaces and create detailed work that larger tools can't manage. Whether you're working on jewelry making, model building, or any project that requires fine material removal, these diamond points deliver professional results. The diamond coating ensures they stay sharp and effective through extended use. At just 10g each, they're lightweight and won't cause fatigue during long projects. Having two in a pack means you've got a backup when one wears out. Your detailed grinding and shaping tasks just got way more precise with these quality diamond mounted points!
