I inspected ER collet holders and collets in a factory. This Chinese factory specializes in exporting. I took a look at their products. The grinding accuracy is high and the quality is very good. The collet holders are completely nickel-plated. Yes, this is helpful to prevent rust. The collet holder can be equipped with ER50. This is required for many large lathes. The specification I want to make is ER32-ER50. Each collet has different needs, you can Equipped with the specifications you need. This is not retail. I want to see how many people are interested. I will discuss with the manufacturer to organize a group purchase.
