7 Best 1.5 Mm Drill Bit – 2026 Reviews
Ever tried drilling a tiny 1.5 mm hole only to watch the bit wander, snap, or leave a ragged edge behind? If you’re working on electronics, jewelry, model kits, or delicate DIY repairs, that frustration adds up fast. I’ve done the research so you don’t have to, comparing the options that actually perform when precision matters most. A great 1.5 mm drill bit should stay sharp, cut cleanly without excessive heat, and hold up to repeated use without flexing or breaking at the first bit of resistance. Material quality, flute design, and overall durability also make a big difference when you’re drilling into metal, wood, plastic, or PCB boards. After sorting through the standouts, here are our top picks:
What to Look For in 1.5 Mm Drill Bit
When choosing a 1.5 mm drill bit, start with the material. High-speed steel works well for general use, while carbide or cobalt bits are better for harder materials. A strong coating can also help the bit last longer and resist heat.
Pay attention to the shank type and fit. The bit should sit securely in your drill or pin vise without wobbling. A precise, well-made bit will give cleaner holes and reduce the chance of breaking, especially at this small size.
Also look at what the bit is meant for. Some 1.5 mm drill bits are best for wood, plastic, or soft metal, while others are made for tougher jobs. Choosing the right type for your project makes drilling easier and more accurate.
Finally, check reviews for sharpness, durability, and consistency. Since small drill bits can wear out quickly, it helps to buy one that stays sharp and performs the same from one hole to the next. Now, let’s look at our top-tested picks.
