I Made a Palm Impact Wrench: Dyno Test + Nailers! 

NOTICE: I designed the original version/prototype of this tool, so while none of us benefit financially from it selling, it might not come as a surprise that A) we like it and B) it does well on the dyno it was developed on. If another review shows up, we'll link to that here in the interest of not being blindly biased idiots.

mechanics always come up with the best ideas....too bad it's a real feat to get it patented...I had a few tools yrs ago and it would have cost $5000 dollars then just to do a patent search...can't compete against the big boys when those kinds of dollars are being thrown around

Ever since I saw this on Astro's website I knew it would show up here eventually. This is genius. Well done coming up with it and getting it approved. This will definitely be helpful in RV and bus engine compartments. Thanks for your continued diligence.

As a millwright that often has just enough room for his hand to be in a machine, I would love having something like this. Great job

It's really satisfying finally seeing your R&D at Astro bearing fruit.

Your work at Astro Pneumatic is finally bearing fruit. I always look forward to your videos in Friday. Thanks.

I appreciate your honesty both in testing and history of the new tool. This is the reason this channel is so highly rated and trusted.

That remote impact seems like a case I don't know what I'm missing until I have it. On newer semi trucks there one particular trans bell housing bolt that I always struggle with. Usually I resort to the long cordless ratchet neutral drop routine, but this seems like a genuinely great alternative to that.

I love that you gave them an idea and they made it, props to Astro for listening to customers!

You mentioning bellhousing bolts made me interested in that frankenstein creation. I'll keep it in mind should I start getting more of that kind of work in the future. Also, I never though about it before, but those palm nailers might be a pretty nice addition for tight spaces when the normal air hammer won't fit...

The fact that there is an Impact like that Onyx is amazing when it comes to the current technology. Amazing job TTC! Keep up the great work!

I can think of numerous times where this palm impact would have been such a knuckle saver. What a cool idea!

You sir have made the million dollar idea congrats on this masterpiece 👏

The palm impact looks handy!

Found your channel about a week to two weeks ago, with the Milwaukee 2767-20 Impact H96A VS H96B, and have been hooked on your other videos since. I don't really have any need to buy an impact wrench, but find you to be both easy to follow and honest facts about the power of the tools you show. Thank you for your honest tests and showing which tools to absolutely stay away from, and showing that Kobalt is a decent battery family for those starting out and with a budget.

@torquetestchannel - awesome idea and tool, can't believe we actually haven't seen something like this on the market before now. I imagine this will benefit quite a few mechanics and even some DIY'ers. awesome job mate!

Super cool, I could see an M12 Fuel or Dewalt Xtreme 12V version of this where the battery, chip sets and switch are remote, with a 0-gauge cable leading to a handheld palm-style brushless motor and mechanism.

You really NAILED IT with this video.

You guys are awesome. Glad to see your ideas getting fragmented into actual development

First warning label I've seen in a long time that is probably needed. hahahha

I think you really nailed it at the end. This will be perfect for the times when the only way to get a regular impact on the bolt is a Frankenstein of extensions and swivels.

That is so dope astro Made a 3/8 and 1/2 palm Impact off your Design and idea @Torque Test Channel

That's a awesome idea. Congratulation on the new product

that's awesome that they built a tool based on your design input. congrats.

I saw this video months ago when it was first posted, been looking for an excuse to buy one and the engineers at John Deere finally gave me a reason. Got it shipping to my house right now, thank you for designing this tool

Dude I've been talking about this exact thing I can't believe you made it and astro listend... thank God

I saw that on amazon! Sick! Love that it's being sold now

You know it's funny, I have to do a clutch job on my 3rd Gen. 4runner soon and I was thinking damn that would be nice to get the bell housing bolts out and then you said it at the end of the video. because last time I had to do one I needed at least 2ft of extensions with an air impact. You've got me sold

I bought the pair just as soon as I saw Clay Koon show one on his MTN video a few months ago. Very few know how many companies rely on Astro for a huge selection of products, I've been to the repair center/warehouse just east of Los Angeles, lots of boxes with high end company names on them there.

Those palm nailers work great with a pneumatic hammer bit to get in tight spots that a regular length one would not

Would love to see how the new 12v skil brushless nailer stacks up against the m12 palm nailer.

WOW! What an awesome idea. Not for me as a home mechanic, but if I was a pro, this would absolutely be in my toolbox.

That air palm thing is easily the coolest tool I've seen, now I just need to find something to need it for lmao

You had me at palm being able to use it as a bola is just icing on the cake.

I sometimes use a palm nailer when I don't have space to swing a hammer under a car. You might need to make a small punch or chisel for it but it's sometimes useful.

Love the creativity!

Added to my wish list. Can't wait. Thanks for sharing.

This is a cool idea. It isn't every day someone comes up with a whole new concept in a mature market. I don't need one, but I'm happy to know it exists.

This little palm gun and a co2 tank is perfect for off road emergency repairs, as in my experience broken parts have less clearance and generally aren’t the super tight mounts that get busted up. I’m seriously considering getting a power tank just for this now, as I’ve been running battery tools for this emergency task previously. But this allows a killer air up and emergency repair kit in less space than both previously took up, which is critical for small Jeeps. Seriously I love this idea and I want to test it out on the trails… just not on my Jeep.

Nice! I need it! I work on compact Japanese cars so this is exactly what the doctor ordered.

Never used a palm nailer for its intended purpose, however i did make a different hammer for one to use as sort of a handheld planishing hammer for sheet metal work. So far it is one of my favorite tools, very fast when needed, yet can be very gentle and controllable. Works wonderfully for hammering out smaller dents in car bodies. As far as air tools in general go, it would be interesting to see a test between two tools where one had some intake work done (port/polish, larger valve, larger hose even) and the other had the same on the exhaust (port/polish, drilled out exhaust ports). On one hand, more air=more better. On the other, making 'spent' air flow out easier would increase pressure difference between in and out, giving the tool more power.

Great video and I like the remote air valve. I worked at a place that had a 1 inch drive and the air valve was on the back of a handle and the nut on the u bolt loosened and pined his hand to the concrete with the air valve full open. Luckily someone heard him yelling and turned the air off at the wall. I don't remember how you changed directions on it but it messed up his hand a little bit.

i've got the small Bosch palm nailer. works great between floor joists and for stuff yer holding together with yer other hand. the palm impact is a good idea

A two handed compact impact wrench. Well that's something I never thought of

ngl, with the advent and power of modern cordless impact wrenches, Ive been struggling to find a reason to have my own air impact, but holy crap that palm design is amazingly compact, especially without the handle

This was a super fun video, thanks!

Some cool stuff, I have been running the p air palm nailer for a few years

Good idea. Very handy tool, no pun intended.

I once used a mini air rattle gun to pull off an L76 crank bolt on a VE Commodore; it was my boss's car. The mini rattle gun had high RPM, it smooshed my hand between the crank bolt/rattle gun and the thematic fans. It tore the skin off my hand.

well you dispelled the notion of some of the applications I was thinking of. But I guess really specialized and repeat processes on certain bolts. Maybe Assembly line work?

That is the most ridiculously hilariously wonderful thing I've seen in a while 🤣

I love that you went to astro n were like bro n they were like bro we got you

Really interesting! It makes me think though, there are kits for regulating down high pressure air tanks for paintball to air tools. How much run time and performance hit would one of those give you on a palm impact? If it works decently it seems like an amazing combo.

Omg that Milwaukee Palm Cordless Nailer is huge @Torque Test Channel

man i just saw those for sale not long ago and was like sic, of course he had something to do with it haha love astro so underrated, so many guys at auto school never heard of em

I was JUST THINKING about something like this. Well, more like welding the end of an auger to a socket and seeing what happens, but this looks way safer and better!

I will definitely look into getting one of these!

I'm blown away guy, this is legitimately a good idea. There may be some spaces a right angle wouldn't fit as well plus the power is excellent in that small package. How big of a compressor is acceptable for running one of these?

I would definitely purchase your new design if TTC got some royalties.

That thing is super cool! sometimes my battery gets in the way of my angle impact or it's too long

Watching this gave me a dumb idea about right angle impacts like the Kolbalt. I wonder how they would stack up on the ratchet gauntlet vs just the Dyno.

I highly recommend doing a dyno test on the new Skil 12v & 20V 3/8 impact wrenches

The tool truck at my work has them on it. Pretty cool

Video suggestion. Tire inflation tools speed and accuracy. I inflate semi tires as high as 120psi and I remove the valve core till it inflates to target pressure. Then install the core. Some chuck just barely bleed air in. Others don't have enough grip to install the chuck and walk away

Someones got influence in the tool world now! 😆👍

Great video! Thanks!

Very cool idea.

That is awesome thanks for sharing the video and idea

The only thing I can see that would make it better would be a swivel end air fitting on the base of the tool where the hose mounts. This thing is phenomenal

When I was working on rollercoasters that would of been amazing. Especially for an RMC raptor

Great job That thing is awesome

I bought a palm nailer from Harbor Freight. Haven't used it much but it's sure nice in tight areas.

Great work....Could we see some of the Napa air tools?

Good stuff! I can see many uses for this. Btw, what tool is that shown at 9:38?

perhaps use a bolt in yer dyno with a 1/2" square hole so you can attach a 1/2" square anvil w/o using a socket. that way you can determine any loss due to the socket itself, perhaps find which brand is best at transferring torque to the load

Oh _suuuuuure,_ you don't care AT ALL how well this tool sells, which is totally why you did a good job engineering it.

I JUST watched a Short where someone used a cordless palm nailer to remove a ball joint. Seems not unuseful.

TTC, has anyone sent in Masterforce (Menards) brand tools? Us folks in the Midwest would love to know if they are any good.

I have an air palm nailer and have only used it a few times. I've grown to haaaaate using air tools. Being on both m12 and skil 12v, I'm really interested in a comparison of that m12 nailer vs the Skil 12v 'Auto Hammer'. To me, the form factor of the Skil looks more functional, and if it's even close to the m12, that would cement my decision.

That's so fun!

Very good idea.. no doubt this could be "handy"...I'm definitely going to buy one...☝️

Could you have a threaded knurled pipe slinding on the hose part? You could fasten it to the head to make a handle, and it would be out of the way when not.

@torquetestchannel have you even seen the old ridgid R8224K. Came get them anymore but would love to see it on a Dyno just got fun

well done man. tx for sharing

Would love to see the test on the skil 12v nailer.

Thats a pretty neat tool! 137$ doesn't seem that bad either for what it is

It would be interesting to see the Klein cordless tools tested

Last astro mini I bought failed. But I put my tool through the ringer. So if I get this I'd have to baby it. But super cool

So about a year ago when I bought my dcf 901 12v I wanted the 3/8s but had to get the half inch as they were the only ones in stock and the thing is amazing imo but looking at the power specs of the 3/8s it seems really down and givin the higher number 3/8s drive impacts tend to give like the new drivers that wear converted recently and givin the fairly high rpm and ipm of the 901 I feel like it would be an interesting test I have a 3/8s swapped one if you wanna test it

Ever person who is a mechanic needs to watch this channel.... would settle a lot of arguments haha 😄

You made suggestion and a company actually made the thing? Wow, that almost never happens anymore. So many companies come out and say "don't give us suggestions for new products or improvements". Always nice to have another option. Take a few "atta boy"s out of petty cash, You have earned them! It is also cool to see a brand name palm nailer. I almost bought a no name one at Menards way back when we were renovating our house but I figured it would blow up on the 31st day and I would be stuck with a paper weight. I will have to look up what Metabo/HPTs warranty is. I still don't understand that rebrand. "We bought a middle of the pack power tool brand. Let's use our high end brand on them but not beef up the design any. No way that will dilute the value of our brand right?"

OH! very nice, I want one. But 160+60 dollar to get it here is a bit steep and switching jobs soon. So next year I know if need to get one. But man such a good idea!

Neat idea

Its like the ridgid 12v palm driver but the 18v that i was looking for

Need it. So need it.

Nice little powerhouse. Also doubles as a medieval flail weapon for the the inevitable zombie apocalypse.

This has given me this idea and hopefully someone will create it but could they not do the same thing with a power cord with a dc plug on one end and a battery attachment at the other?

Would love to see different brands of palm nailers

Ridgid used to make a palm impact driver, R8224.

really just made an entire new tool
