I work How the cooling is installed. And it's always good to have a good deburring tool with you. I used the tools from Home Depot, they're really only good for a while. Cheap material and then I saw a colleague with this deburring tool. First I asked where. Do you understand. And here. I'm the best at removing burrs. size and quality. If you are interested, don't think much, you will be happy with this purchase.
