HART Air Die Grinder

Hart 1/4” mini air drop die grinder overall has good quality out of the box. Came with the collet locking tools and threaded quick disconnect. Very useful on many small to big jobs. Only thing can suggest that some teflon tape for threads would come with tool.

The Hart ¼ inch air grinder comes with 2 wrenches, ¼ inch NPT male plug, I have a small hand and it fits my grip well. There is a safety trigger so that it doesn't accidentally run. The lever to make it run would be easier with a little bigger hand as for me it is a little hard to push the trigger up while pushing the lever down for it to run. Once it is down it is fine and works smoothly. There is a plug on the back side of the grinder covering the exhaust that must be taken off. Also, when you put the male plug in and then take it out. There is a little bit of oil on the threads. Makes it much easier to put the plug in without cross threading and it tightens easily. Also, easy to remove. Max. Load is 25,000 RPM The Collet size is: ¼ inch Operating air is 90 PSI Air inlet i: ¼ inch The hose size that is recommended is: (ID) NPT Avg. Air consumption is: 3.5 CFM @ 90 PSI This grinder is very simple to use. The air hose connects easily. Put your grinding piece in or your counter sink as I did and start working. I dropped a few holes with a counter sink in a 4 x 4 that is part of my fence. It had enough power. I will be using this a lot this spring as I need to grind off some nails and wood slivers on my fence and replace some of the longer screws. This will make it much easier for me to have the head start for putting the screws. The only thing that I really didn't like was the way you have to push the safety, to be able to squeeze the trigger. If my hands were a little bit bigger and I had a little more strength It would be no problem.

The size makes it easy to pack into the top tray of our small rolling compressor. it also makes it easy for arthritic hands to use, and in tight spaces. It arrived just before we started a bath renovation in an old home with only one receptacle. It was powerful enough to run a small reamer. A locking latch on the trigger is quite easy to engage, but locks back when you let off the trigger (good safety). The only drawback would be if you don't have a compressor or only a large one too far from your project.

I'm very pleased with this mini die grinder. It'll make a nice addition to my arsenal. It's collet is 1/4”, with a recommender hose size of 3/8” it's maximum load speed is 25,000 RPM. It comes with 2 wrenches, and a 1/4 NPT male plug. I have small hands, and it's easy for me to handle. I'll be purchasing some additional attachments. It has so many household uses, but I'm going to use it straight away to grind some rush spots from the door jam of my car, in preparation paint. Very excited to have.

Out of the box, it's small, but that's what you actually want for a hair dye grinder. The big ones are hard to work with especially if you're trying to do auto work, carve wood, sand blades, remove rust, or even smooth surfaces. The bigger ones Can get in your way. The positive about this grinder is it does pack power. Because the power comes from the attached compressed, air tank which you hook it up to. This little guy can actually be good for large jobs where you need a powerful grind. I bought this for my husband to replace one he accidentally ran over.
