Based on my experience this drill bit is a game-changer for any industrial or scientific PROJECT .The TiN coating ensures long-lasting durability and precision, while the 1.5mm shank size is ideal for smaller holes. The drill bit worked flawlessly on various materials, including steel and aluminum. The only downside is that it is slightly more expensive than other carbide drill bits on the market. Overall, I highly recommend this cutting tool for anyone looking for top-notch performance in their projects..
