5.0 out of 5 stars Great value, glad I have these in my tool box. Not my first Astro product, and won't be my last.
Reviewed in the United States on February 28, 2019
Pattern Name: Grinder KitVerified Purchase
Both units work pretty well and the included bits have held up great as well. I did buy a second set of bits to keep my aluminum and steel bits separate and I use these ones on steel and stainless and they've held up great. The grinders themselves work pretty well. As others have mentioned, sometimes they get a little hung up and won't spin but manually spinning them and then pulling the trigger seems to set them straight. I also had issues with the collet being difficult to loosen on the straight body tool and broke both the wrenches it came with. I made a set out of thicker 1/8" material and left a little more meat on the sides of the wrench and those have held up fine. Wish they just shipped with adequate wrenches in the first place. I'm also more careful to not overtighten that tool. I recently let my girlfriend use it for a stainless project she's working on and forgot to tell her about not overtightening and had a tricky time loosening it again. I'm still within the one year warranty and plan to send it back to Astro for service to see if they can replace the collet assembly for me. I suspect a burr left behind from manufacturing causes the issue for me. I called them to ask what they could do when I first had problems and 1) Got an English speaking human being within 30 seconds of calling who 2) Covered their warranty policy and estimated turn around time on repairs. I've bought other Astro tools and once had a punch set show up without writing on one of the punches in the set. A quick phone call later and Astro mailed me out a replacement with writing on the tool at no charge to me. They're California based so shipping for me is quick and affordable if I ever need to pay for it. Will be continuing to buy Astro as I build my tool collection up. They are built well enough for my needs and offered at relatively affordable pricing when compared to similar tools from more well-known companies.

I love this set! the grinders are great, especially for the value. You dont get too much torque with these and they only have a one year warranty, but the feel in the hand is great. They dont get cold like the economy metal handled tools. Theyre fast, compact and light. I just love them. They also dont vibrate in the hand a ridiculous amount like some die grinders ive had. The greatest surprise about this kit was the carbide bits though. I was expecting them to be pretty disposable and overall not that great, but they are wonderful.

5.0 out of 5 stars If it doesn't spin up on the first use...
Reviewed in the United States on February 7, 2024
Pattern Name: Grinder KitVerified Purchase
... and the first thing you do is send it back for a replacement, you might not be qualified to be using power tools.
It's an air-motor, it's not broken in yet.

1. Oil it generously (with an air-tool oil... I'll spell it out for the slow guy in the back who said his replacement was also "frozen").
2. WITHOUT a bit in the collet, and NOT hooked up to air, squeeze the trigger fully and hold the tool upside down so that oil can enter the tool.
3. Spin it by hand several times in the direction it normally spins (CCW if you're staring down the barrel) to get everything oiled and moving.
4. Set your air pressure to the max this motor is rated for, 120 PSI. Don't chuck any bits just yet, since it might still need a hand spinning up.
5. Hook up your air line and go full throttle. If it didn't spin, just keep the throttle on full and give the collet a nudge in the right direction. When it is spinning, keep it spinning, but turn the pressure down on your compressor or regulator to the motor's minimum of 80 PSI. Keep it running for another minute or so, and it's good to go.

I have had minimal use so far but both the drivers and dies have performed well. I had to elongate a few holes in 6mm plate by a few millimetres not a problem, could put on a decent amount of force before they would stall out. Happy with the purchase.

5.0 out of 5 stars Great little grinders
Reviewed in Canada on August 12, 2015
Pattern Name: Grinder KitVerified Purchase
For the price, these are fantastic. The fit and finish is great, and although the die case will probably not last long, the dies seem to be of similar quality to much more expensive ones. Both tools have worked well through a few hours of hard use, which is good enough for me.

One very nice feature is that both of the wrenches the tool came with are identical; each has one side for the chuck and one side for the spindle. I don't know why none of my past die grinders have been like this, but I like it.

One slight downside is that although the bits have a case, the tools themselves don't, which is a bit of a pain.

excellent kit for the price. I had a problem with an air leak on the angled die grinder(90°), you can hear the air coming out from the exhaust. I've returned my first unit(major air leak) . my 8 gal compressor was working like crazy non-stop
on my second unit , on the angled die grinder again (small air leak)
I'm on my third kit and its still have the small air leak problem. but decided to keep it because you won't find tools at this price.and it doesnt seems to affect the performance of the tool like the first one I had
the rest of the kit is perfect, I never had air leak on the straight die grinder.
excellent carbide burr set
