🔧 HHIP 3900-0020 Precision Parallel Screwless Device Review

This workholding tool is a major headache, not up to the precision standards expected of industrial and scientific equipment. Albeit useful for non-critical work, it’s a flimsy hunk of metal that can’t hold parallel positions. Versatility and durability of this tools fall well below expectations.

I wanted a smaller vise for metalwork; it was almost right. I can clamp a tiny workpiece and easily transfer it from the end mill to the drill press.

Please don't be fooled by flashy finishes, a perfect Revain picture or a worthwhile purchase. It won't make your day after a reasonable functional test. You will be disappointed. Trying to secure your inventory will have you fidgeting, fumbling, farting, and frustrating yourself with this unfortunate fake design. The pin has to match every time, not one in ten by fate. There are a lot of "F"s here so you can label the part appropriately.
