Boquite Engraving Jewelry Machine Tools, Engraving Handpiece for Pneumatic Engraving Machine——Metal Engraver Hand Tool

quality was better than expected, does still require some adjusting here and there to work with my DIY pneumatic graver set up but afterward i can get it to hit quite hard to hob off a lot of material.

I have built pneumatic driver unit like Rick Alexander on YT but original handpiece stopped working so desided to try this item. Had to modify it to make it work. Hammer piston inside is too heavy and springs too tight. After my mod - works as it should. Check YT channel "ROBO HOBO" to see how Shawn modified similar product...I like removable tip with graver bit. Comes with extra one...

Works pretty good. It would be great if it came with instructions. For example how to assemble & disassemble the item and how to adjust the impact of the piston. Othere than that it works fine.

Works great!

Complete garbage

Had to adapt air line It was too big Fixed and seens to work

The tubing that holds the handpiece from the impact machine is too large to use with the Vevor unit. I tried to step it down so i could use the better handpiece than what came with the machine. This is very well made and should work well just check your sizes.

Using a diy setup with a modified h.f. compressor, all I had to do was reverse the piston and spring inside the hand piece and it works SO MUCH BETTER than my diy handpiece I crafted out of brass fittings. I'm really happy with this for my application.
