Welcome to Last Tool Factory LLC.

Founded in 2008, Last Tool Factory LLC, headquartered in Rochester, New York designs, manufactures, and distributes our own specialized tooling for the machining/metalworking industry. All of our products are proudly made in the USA. Last Tool Factory LLC was started with our patented ER Combination wrenches.

The Last Tool Factory was founded by Long Nguyen after 26 years in the machining industry. Long became frustrated with the time he was wasting using 8 different wrenches to accomplish loosening and tightening all of the varied collets, nuts and tool holders he would encounter on a daily basis. To save time, Nguyen set out to combine all 8 of these wrenches into 2. He not only combined all 8 of the most popular wrenches in the industry into 2, but he was also able to do this economically, safe and maintain a high quality standard. The bottom line is that you will only need these two wrenches to replace all of the others on your tool bench. These wrenches will replace: ER40, ER32, ER25, ER20, ER16, ER11,Retention knob/pull stud and Vise wrench. We assure you that these wrenches will last you for many years. We guarantee to save you time and money. These will truly be the last tools you will need to buy!
