Ordered on Friday last, free delivery stated this coming Friday, arrived today. This has happened several times to me lately on Amazon orders, can't help but wonder if they're trying to sell faster shipping rates. Not complaining about the early delivery, just wondering.

While I haven't fired it up yet, first impression is this thing is very tiny. Easy to grip, light, manoeuvrable. Bonus: 4 spare cutters, not just two. Also included an 'M' type air coupler (I use 'A'), along with two spare bearings.

I'll have lunch, assemble it & give it a test run.
 
General observations: 1) Don't care for the rear facing exhaust port. The reason this is an issue is because the barrel of the body is so short, it exhausts between your third finger & your pinky, which can get cold. You can rotate the port, but then it exhausts into the palm of your hand or into your face. I would have preferred a front exhaust. Not worth losing a point over, but an annoyance. 2) As noted above, it's quite noisy. I rarely wear ear protection on a die grinder unless I'm going to spend some time on it. With this, I wore hearing protection. 3) The guide plate that rides the material you are chamfering is small, about 1-7/8" diameter. With less than half of that on the material, it's sometimes difficult to keep it flat on the surface. The plus side to this is that you can get into some fairly tight places with no interference from the guide plate. 4) It fits well in my hand & the throttle is placed nicely. You grab the tool & it just works. 5) It was leaking a very small amount of air internally at rest. I'll have to watch that to see if it improves or not. 6) A hex wrench for depth adjustments, a Torx wrench to change out bearings (2 extra) & bits (4 extra), an extra o-ring for the air fitting and a parts breakdown accompanied the unit.

The good: 1) This thing works like a hot damn. Edged a 1/2" steel plate quickly & efficiently. That's what it's supposed to do. 2) As I noted, a bonus of two extra cutters were in the bag.

The bad: 1) No instructions. Can you figger it out? Sure, but I loosened the screw on the label & tried to adjust the depth of cut there before I figgered out it was the actual ring that needed loosening & adjusting. 2) The depth scale on the ring seems to indicate 1/10 of a mm. However, if you decide that you want to trim more than a mm, you need to keep count of how many times you've rotated the adjuster ring past 360 degrees. One rotation, 2 rotations, plus the tenths. 3) The machine screw to change the bearing/cutter is a Philips head. I hate Phillips screws. The wrench they included for that is a Torx. WTF? 4) As noted, a type M air chuck was included. If you have M air fittings, you're golden. If not, you soon discover that the air inlet thread is not a pipe taper, but an o-ring fitting and the air inlet is plastic. You don't dare screw in a 1/4 NPT fitting of your choice for fear of cracking the air inlet. As such, you'll need to buy/make a whip adapter, unless you want to change chucks every time you use it.

Final score: 4/5. It lost a point between that Phillips screw and the air chuck issue. The rest of the tool is metal, I'd have preferred a metal air inlet threaded 1/4 NPT. We'll see how the tool performs over time & update accordingly. I don't expect to use this a ton, but I appreciate the utility thereof nonetheless.
 
I agree the exhaust is in a stupid spot, but what do ya do

I have M and A tools, actually quite a few that have that same non npt threaded M fitting (a bunch of passlode stuff), M is by far the most popular, i imagine thats why most things come with an M fitting, and why they choose it

anyways, a universal chuck is the best solution, i have a few of these from milton, best chuck ive ever had, accepts 5 different fitting styles, and that safety collar can be slid up and down to stop any leaks when you unhook the tool...ive found just about every air chuck ive ever owned starts leaking after about a year, this thing is going on 3 and still works great, they are about 30$ per though, thats the downside

So...reviving this thread, because I found something in the kitchen tonight.

I don't know how I missed it in the box. It must have fell out when I pulled it from the bag and I never noticed. Only noticed it tonight in the "junk bowl" on the kitchen ledge. Wife must have found it and put it there. Good news regardless, as that means I didn't get screwed on the deal lol.

Side note, it's still working great, and on the original inserts, and I've use it quite a bit at work. Both on steel, and aluminum, but mostly steel lately.
 
Looks like Princess auto is carrying these now. And they're on sale. Probably still find one cheaper online, but the takeaway here is that you can walk into princess auto and get replacement inserts now. Could be handy for someone, thought I'd share.

Mine still going strong on the original edge. Semi daily use in aluminum and tool steels for almost a year. Should probably rotate the edge, but it's still cutting and acceptable. Still loud, and the old cranky guys up front still complain.......
 
I wish you hadn't done that. It inflamed my chronic tool disease, and now I'll have to fight it for a week. Down, boy.
I'm not a fan of plastic tools or black. I find that I lose things readily in the shop if they are black. I had to put yellow bands of tape on the black flashlight after my wife got tired of finding it for me.
This one does look good. Ouch!
 
I've found that unless the edge is smooth or machined, any ripples from plasma cutting, for instance, will be transmitted to the chamfer and magnified. I ended taking mine back to PA. It won't do for my needs, but still is a good tool.
