According to my experience this Industrial and Scientific drill bit is a game-changer in the cutting industry. The WeldTec auger is very strong and durable, making it the perfect tool for heavy duty drilling jobs .It can easily drill through wood, plastic, and metal, making it a versatile choice for any workplace. The only drawback I found was the high cost, but the quality of this product definitely justifies the price. Overall, I would highly recommend it to anyone in need of a reliable and efficient drill bit..
