2 in 1 Air Chamfer Tool,Mini Pneumatic Chamfering Machine,45 Degree Beveling Machine for Metal,Wood,Acrylic Deburring and Trimming (Black)

Cool little tool - been using it for about 3 or 4 months now. It lives on the tool shelf behind the big lathe. There is always an air chuck and a hose there so whenever an edge needs deburring or a quick tiny chamfer she's handy. I haven't used her with any alloy steels - mostly on mild steel and the carbides look fine after substantial use. She is comfortable in hand, the trigger is easy to use. It is a nice little convenient tool to have in the shop.5 Stars for The 2 in 1 Pneumatic Mini Chamfering Tool

This is a pretty decent tool that will get the job done.It's not particularly high end but it's also not low and I would compare it to something you get like at harbor freight

This chamfering tool is a handy addition to my workshop. It’s lightweight and easy to handle, which makes it great for both metal and wood projects. The tool does a solid job of creating smooth, clean edges without much effort. However, it is on the louder side, so be sure to wear ear protection while using it. It's not a dealbreaker, but something to keep in mind. Overall, a solid tool for anyone looking to make quick work of chamfering tasks.Pros: Lightweight, versatile for metal and wood, efficient.Cons: Quite noisy, requires ear protection

So far I've used this to put a nice edge on a basic particleboard workbench top I'm installing. So not exactly pushing it to its limits yet though it may come occasionally useful for metal work as well I hope.Setup was a bit… vague… and I had to figure out a couple things on my own:* to adjust the depth, there's THREE set screws but you'll likely only want the two on the bottom plate. I accidentally loosened the gauge part and had to recalibrate it. (As far as I can tell, it's basically just like a "percentage" depth 0 - 10% - 20% etc. around to 90% - 100% shared with zero. So in order to align it again I bottomed the main plate out and called that 0 / 100% 🤷 No clear instructions about that but it does seem to travel ± its whole range in ± one rotation.)* To fit what to me is the "regular" fitting on, I too had trouble with air leaking. What worked for me was to steal the o-ring off of the fatter anodized barb fitting and move it over to the silver quick connect one. And then tighten it down all the way! Hopefully I didn't cross-thread it or anything but with any luck I can just leave it on permanently now 🤞This thing is LOUD, it sounds like a tire shop (if the tire shop were a foot and a half from your ear) and I very quickly grabbed ear protection. But it seems to run right and feels solid and precise in the hand 👍

This chamfering tool has been a valuable addition to my workshop. Its versatility in handling both 45° and arc corner beveling has streamlined my projects, and the adjustable speed and depth settings offer precise control over the chamfering process. Overall, it's a reliable tool for achieving clean and accurate edges on metal parts.

Definitely a helpful tool for any machinist. Sturdy hand feel. Works pretty well. Definitely takes a bit of practice to become proficient in using it. Overall a good investment. Works just as well as bigger brands.

EDIT: Updating after more work with this tool, and my five-star review stands strongly. I used it to chamfer and put a nice lead on a bunch of 7/8" holes drilled in mild steel bar while I was upgrading the box blade on my tractor, and it continues to do a beautiful job. Not the slightest sign of struggling under load while it put a 1/16th chamfer around each of the holes and left them absolutely beautifully consistent! After about two dozen hole edges, the inserts still look brand new.The first thing that struck me when I unboxed this thing was just how *tiny* it is! The entire tool will fit in my palm with room to spare. But for how tiny and compact it is, this little guy *really* works! I'm running it at about 1/2 on the variable-speed dial, and it does a super job of putting a neat, controlled chamfer on the edges of stuff right as it comes off my chop saw.The body of the tool is a plastic or resin of some kind, with an aluminum end down where the air fitting is, and up at the business end. The plate it slides on is actually aluminum as well, which I did not expect. The only downside I've run into with this tool so far is that it is *loud*. I mean, screaming, howling, ear-piercing loud. You will *definitely* want ear protection with it. I'm going to use the heck out of this handy little thing!

I got this to replace one that's on its last legs. It's an almost identical tool so, unlike many air tools, I wouldn't consider this to be a 'lifetime' tool, but a consumable, as many electric tools are.No complaints, though, it more than paid for itself.The fact that it is effectively a one-trick pony turns out to be an advantage. No setup time and equally at home working on stainless steel, softer metals, plastics and wood, all without fussing over bits and settings.It takes up so little space that I have two set up now, one set up with radius blades that I mostly use for wood, and one with 45 degree chamfer blades that I mostly use for metal.That will pretty much limit blade changes to replacing worn blades, eliminating a fussy job.The air inlet is threaded with straight thread, not NPT tapered thread as US standard. That makes using a NPT plug like the type 'M' industrial plug included troublesome. I had better luck using a Milton brass plug and yellow teflon tape to get a leak free joint. It works, but mixing up threads like that is less than ideal.Chips, particularly aluminum chips, tend to collect in the head behind the flange. Mostly noticeable if you go to change the depth of cut.The chips can interfere with that.Check the bearing and blade screws periodically, they're notorious for loosening up. I considered using a drop of blue threadlocker, but the soft screws would probably just strip their heads making for an even bigger problem.
