"PROTEX" radial arm drill press 12 brands
This is a comparison of the "Protex" radial arm drill press. It is sold by just about every equipment vendor on earth. I credit this "model" to Qingdao Protex Machinery Mfg. Co. Ltd. in China but there are copies of copies of copies so who knows where yours' comes from.
It is interesting to note that some of the less convenient adjustment methods I've replaced with brass screws with plastic handles. Everything on my drill press is metric so finding the plastic knobs could be problematic but not impossible. The only real variation is an idler wheel in the top belt drive case to add additional speeds. Oh yes, and the feed handles vary from one machine to another.
