When I tried this product for the first time, I was BLOWN away by its accuracy and precision. The TOOLMAKER Clamps are well-made and ideal for holding items securely in place while I work on them. The clamps are easy to adjust and hold strong, even under heavy pressure .Theyre also lightweight and easy to handle, making it easy to move them around as needed. Overall, I'd highly recommend these clamps to anyone looking for high-quality industrial and scientific workholding tools..
