Outstanding tool for a Bridgeport especially if youre doing more than 1 part. makes swapping tools a breeze and keeps runout well. with tool holding heads you can buy seperately such as little collets, chucks, or solid holders, you can hit the gold button, twist the tool head and drop out your cutter and put a new one in. The tool head itself works however the original R8 shank was modified at some point in the tools lifetime. This will require either holding onto the tool via a 3/4" shank r8 collet or similar, or an extended draw bar/replacement of shank on tool to work again without holding onto the shank. For this reason, condition is listed as "For parts or not working" and price has been adjusted.
