Great time saver . works well with no issues, carbide cutters last a long time even on T1 steel. chamfer size is adjustable.

Great adjustability and plenty of replacement carbides. It basically a mini router. Nice value for the price.

Great quality works great

Powerful little unit. Works great

So as you can see in the picture, you can absolutely burn thru chamfers QUICK with this tool. All those tubes in the pic and about double that amount have been chamfered with the original blades on this and I'm still going (you get a lot of spares btw)! I had done all those in my first day with it and barely knowing how to use an air compressor so if a noob like me can do it I think anyone can! I set the regulator to 90 psi, the depth is set to 0.7 for these deep chamfers I wanted. I set the speed on the tool to max, and then I learned to shave off a little at a time to start with. That initial bevel you'll want to get as deep as the tool will allow per your depth setting by shaving off a little at a time. Don't try to shove the tool against the tubing and take off the full depth in one pass or it'll skip around on you. Tense your muscles on both arms so the tool doesn't skip around and the tubing stays as still as possible. One you establish a full depth bevel in a tiny section you can push the tool hard inward and ride that bevel at full depth around the entire perimiter. Basically that starter section gives the tool like a rail to ride on and will help keep it from skipping around on the rest of the cut if you keep your arms tight. Or you can just "small passes" your way around the entire thing. It's probably better for the cutters that way but I'm impatient. NOTE that I do have a pretty chunky compressor to run this thing, it's old but the specs are high. 5HP, 20 gallon and ~12 cfm (got online for 60$ facebook marketplace). I also read online that you want a thick hose and not too long one either so you don't lose pressure as much on tools. My hose is 3/8in and 8ft long if that helps, it was 12$ at harbor freight. Like I said I think the tool, if run with a strong enough compressor is VERY safe, the exposed cutting bit is a tiny little triangle that you'd have to be TRYING to touch. In contrast trying to do all these bevels with an angle grinder or a sander would have taken forever and one slip up might have you getting cut by the blade or worse. Not to mention you'd never get anything as uniform as this with either of those tools imo. Now for the only negatives I've had with this so far. There are little pins holding the switch arm onto the device, these pins aren't locked in place, peened or anything like that. They are just friction fit in, and will slowly back out on their own from the vibrations the tool makes! It's nothing major since the arm is just really a safety for the REAL switch which would still work if the whole thing came off but still. It didn't take long for these pins to start walking out on me, I put a small glob of industrial hot glue on both sides of each pin and so far they've stayed put. Hopefully keeps that way! Another small nitpick is the grub screws holding the depth setting also like to back out from the vibration. You need to REALLY crank on those screws with the key once you get your setting or loctite them in or the tool will start changing depth on you mid-cut, ask me how I know! All in all would recommend, I really wish someone made a battery or direct wall current version of this tool tho. Having to wheel around this giant compressor and dealing with air hoses, etc, is kind of a pain. But as far as I know no such tool exists, so honestly for the results and efficiency this tool gives you it's worth the hassle imo.

Great tool for taking the sharp edge from drilled holes and cut edges. Easy to use, the spare cutters were a good addition.

wonderful tool, does a good job of knocking the corners down quickly. Wish I had known about this tool years ago.

Good and fast

Cinese ma ben fatto

Great tool good quality

cet outil me fais gagner énormément de temps pour l'ébavurage de mes pièces usiné. Le chanfrein est propre.

Allt funkar så bra....

Prise en main pas terrible, l'air sort directement sur la main, désagréable. Efficace mais n'attendez pas de bons résultats sur du matériaux dur.
