## Questions & Answers

**Q: Is there a trigger mechanism, or is it just always on when connected to air?**
A: There is a twisting mechanism that controls airflow. This allows for variable speed and shuts off the air completely

**Q: I am looking to mount in a lathe quick change tool holder  (any one know what the body OD is the blue part)**
A: 0.6250",15.87mm according to the mitututoyos, I would make a dual ring assymbly mounted to a tool post, bore the rings six .625 split one ended, drill and thread it to screw the rings closed further to grip the tool. But as always there's more than one way to go about things, I'm sure your could find a 1/2 inch boring bar holder and drill it ou55oversize and put the screws to it

**Q: It is leaking air from under the rearend holder when turned on. It does not spin. Just shoots air out of the back. Hose/hose fitting are not leaking***
A: I just returned one with the exac problem. Ive been working on and off for 50 years with small type air grinders but this jewel turned out to be a paste. I was Really disappointed that it didn’t represent its maker very well. One of these shouldn’t be seized just out of box, oiled and connected with correct air supply.

**Q: is this any good for use on resin counter tops?**
A: I would say it depends on what you're doing. If you're cutting the counter tops then no but if you're etching a design I'd say sure why not.

### ⭐⭐⭐⭐ good but pink neiko is better
*by P***Y on July 24, 2014*

I have gone through 2 of these and 3 pink neikos. I use them every day for work on hardened die steel and to work in the weld on repairs. Also to scarf out porosity and to use for engraving. They will last for 5-10 years with light use but for every day work even the $500 dynabrides breakdown. That is why these are so good for $39 when i breaks a new one is so very affordable. I always keep a new backup. So.. after using both this and the Neiko over 5 years i went through 5. I work with molten aluminum so i have had the hoses melt a few times. With the pink Nieko simply cut the hose and screw the rest back in and tightent the clamp. For that the Neiko is far superior. The astro hose is crimped so it is much more difficult to fix. I discarded the entire line and out a steel braided like on and crimped it. The neiko is better i like the blue color better but performance us hat matters. These 2 are the only ones worth buying the soiux and chicago pnuatic. Are 3 times the price but only offer a 10% performance boost if even that.. for 99% of jobs these pencils l ginders get the job done, but for that once in a year job the faster turbine grinders 75,000rpm i think are much easier. They are insanely expensive and break down often. ******Important these are pencil grinder and do need to be oiled. Do not go overboard just 1-2 drops every day of use. Get too much in there it will slow it down. Much worse though is not to use oul at all some who came from turbine grinders which dont use oil make the mistake of not oiling them. They get very hot and will run slower and slower. Buy the neiko it is the better buy. Either way this tool is soo handy even if i did not work in tool and die i would buy one. Just a very handy tol.
