DIYers and craftspeople, these 0.8mm HSS twist drill bits are perfect for those precision jobs where you need small, clean holes. Made from high-speed steel, they're tough enough to handle iron and aluminum materials without dulling quickly. Each bit has a straight shank that fits standard electric drills perfectly (drill not included, of course!). The specs are spot on: 0.8mm diameter for both the bit and shank, with a 65mm flute length and 100mm total length - nice and long for reaching into tighter spaces. The gray finish is durable and helps with visibility during use. With 10 pieces in the pack, you've got plenty to work with and replacements when needed. These are seriously precise bits that deliver clean, accurate holes without wandering or breaking easily. Perfect for model building, electronics work, jewelry making, or any project requiring small, precise drilling. The quality is impressive for the price - they're well-made with sharp cutting edges that last through multiple uses. Whether you're a professional or hobbyist, having these tiny drill bits on hand saves so much frustration when you need to make small holes in metal, plastic, or wood. They're one of those tool kit essentials you don't think about until you need them, then you're so glad you have them!
