The Solution To Spot Welds & Metal Prep

The Astro 3037 is the industry's newest and most popular way to remove spots welds quicker and cheaper than traditional methods. Other common tasks include metal prep and cleaning up welds.

360° Adjustable Arm

Adjust arm angle as desired for better access with the simple turn of an Allen bolt using the supplied wrench.

Universal Belt Fitment & Quick Changes

Designed to fit nearly all 1/2" x 18" belt brands and styles, the 3037 auto-latches the arm open when changing belts, then auto-tensions by pressing the lever release.

Adjustable Speed

RPM adjustment located on rear of handle allows for fine tuning the speed required for your application up to 16,000RPM.

Owned for almost 4 years now, great tool
Having owned this handheld belt sander for almost 4 years now I can say this is a great tool to have on hand. I've used it for more projects than I ever expected to and for some work it's been indispensable. With this tool and 3M sandpaper you can tackle just about anything. I added a photo of a recent project to show how tight the workspace was and having to grind off a rivet head, no problem with this tool.

Have not found anything I dislike about this sander. I use it for bodywork and it works great for spot welds and taking metal off. One tip is to put the belt on the back pulley first and make sure it's seated on the pulley. The sanding belts that come with it aren't the greatest. Buy some quality belts. I highly recommend this tool.

5.0 out of 5 stars Comparison w/ Snappy Tool Truck's Chinese Sander
Reviewed in the United States on May 25, 2017
Size: 1/2” x 18”Style: SanderVerified Purchase
The BlueP version the Snappy guy has on his truck is more than four times the price and is still made in China I so decided to try this one first. At $100 I figured I'd be happy if I got 6 months out of it. I've used the blue tool extensively as an auto body professional but never talked myself into buying one for myself. Here's my side by side comparison

Noise - Blue wins. The Astro absolutely screams while you're tearing into metal.

Belt Wear - Blue wins by a margin. I received the newer version of the astro that does have a rubber wheel instead of the older steel wheel but it still goes through belts just a bit faster than the blue tool.

Belt Change - Major win for Astro. Press the tip back towards the body and it locks in place.. old belt off, new belt on, release the tensioner, and you're ready to go. The Blue has no lock feature. You must remove a dust cover then wrestle with the tensioner spring as you slip the belt off and a new one on. Not an impossible feat but far more difficult than the Astro

Speed adjustment - Astro. While both tools are easily modulated with the trigger, the astro has valve at the back of the body to set the speed. This is great for cutting on large body panels with lots of spot welds. Instead of balancing the speed by hand on every cut, just find the right speed and have at it without worrying about cutting to deeply or putting a ton of heat in to inner panels.

Belt Drive - Astro again. The drive wheel on the astro has very high shoulders on either side that prevent the belt from sliding back and forth on the wheel. I've found this to be a problem on the blue tool especially when pressure is applied at the tip, the belt will slip and then slide off of the drive wheel not only disabling the tool but shredding the belt. This is a non-issue on the astro.

Angle Adjustment - Both tools require an allen key adjust the angle of the belt but I have found the Astro to be a bit faster on the adjustment due to lock bolt placement (when I can find that key).

User Protection - TIE. The Blue tool has a dust cover over the drive wheel that also protects the user from accidental contact with the spinny wheel of pain. While the shoulders on the Astro drive wheel offer adequate protection from pinchy ouchness and lost fingernails I could still see something getting in there and taking a ride around. What brings the astro back for the tie is the mudflap. In overhead and out of position spots the blue tool will spit metal dust right back at your face at alarming speeds and sometimes you just have to sit there and take it or grind blind and risk missing. The little flap on the astro deflects a good amount of this backblast and makes those trouble spots much less painful for the user.

If this tool were $200 this would be a 4 Star review but the fact that I can buy four of these before the blue tool or the dynabryde earns the extra star. Also worth noting, having the blue tool rebuilt out of warranty (I believe 2 year) costs the same as a new astro AND the astro has a 1 year warranty.

Will update review after 1 year. Used full time for auto body repair.

Update: January 2021

After 3 years and 7 months I finally broke it. The body and air motor are still solid but one too many drops on concrete cracked the tensioning collar on the arm. Like I said in my original review I would have been happy 6-12 months but got 3 1/2 years out of it and I am HARD on my tools. If I were more careful I dont see why this wouldn't have lasted another 3+ years. I've already ordered a replacement. If you need one, get this one

Important note: It looks like the wheel replacements are now easily available on amazon but were not when i first bought. This tool accepts the 3M replacement arm assembly (Part no. 33588) which includes the middle bar, front adjustsble head, and a new wheel. If you run into any issues with side to side runout in the arm I recomend ordering the 3m unit which should be available through your shops supplier or can be found online.

4.0 out of 5 stars Works well
Reviewed in the United States on September 23, 2021
Size: 1/2” x 18”Style: SanderVerified Purchase
I have quite a few things from ASTRO. Mostly pneumatic tools, but also some crimper and sockets. Very happy with all. The only reason this got 4 rather than 5 stars is that between the throttle lever and trigger, I can't make it go as slow as I want. I have reduced my line pressure to do so, but would rather have the convenience of doing it at the tool.
This is a common complaint I have with air tools. For delicate deburring of parts I've made or things like that, I want slow speed and fine control. I'm not a body shop guy, and am not known for being in a hurry. This trigger would seem great on an impact wrench, but for this or a small die grinder, I would like finer control.
This is every bit as good as more expensive tools, and better than cheaper ones I've tried. The fact that I've seen Astro stuff for years, and the bit of paperwork in the box, and that they actually have a website all seem to suggest that they might actually have some customer service, but I have never used it, so I don't really know.
