Mini Pneumatic Chamfering Tool,JIUNENG Metal Chamfer Tool with Replace Blades（C 45 Degree/R1.5 Arc) and Bearings for Metal Edge Beveling

Used this on one of my projects and it has changed my whole outlook on the grinder for making a bevel. It makes a very high pitched whine but it's small so obviously that will happen. Once I wore off the paint layer on the slider (?), it was great. The paint made it grab a little bit but once it's metal to metal, the little guy does an amazing job, even on quarter inch plate with the cutter bit fully extended.

Finally got a chance to use and it snapped in half right off the spindle. Waste of money

Item only lasted about 30 minutes before it fell apart

Good tool but requires at least 90 psi and a lot of air flow. I think a smaller portable compressor would have difficulty keeping up with it. The 1/4 inch standard fitting is not very good quality but better quality ones are readily available. Uses standard triangular carbide cutters which are available from many sources and also the pilot ball bearing is a standard size and replacements are cheap. The chips it throws are very sharp so protective clothing and eyewear are highly recommended. I was expecting it to be loud but it wasn't bad at all. Supporting the air hose (such as throwing it over your shoulder) can make controlling the tool easier. Well worth the price.

The media could not be loaded.  After reading all the reviews I almost didn't buy the tool. But I really wanted to test the process and the tool itself. I knew it probably wouldn't be production tool but before I invested in a production quality tool I want to see if I even wanted to chamfer all the outward facing edges.Here is my tips on making the toll work as expected.1. Oil the tool before use with air tool oil.2. Make sure everything is tight. (Insert screws, Collar sets, Etc)3. If using on hard metals (Steel) set to the lowest speed. (Lowest Cutting Surface Speed)4. Cut in the conventional milling direction NOT climb milling direction. (In video is convention milling direction.)5. Hold tool firmly don't be a snowflake & maintain a consistent federate keep the cutting edged engaged. (This will keep you from burning up the inserts.5. After chamfering hit the edge with a DA sander to deburr. (This is not a deburring tool it WILL leave sharp burrs.)I have chamfered about 65 linear feet with single edge of the insert and it's still good. The bearing is still good. The bearing (683ZZ) is $8 for 20 of them on Amazon sooooo yeah nothing to cry about. Also you can get some good inserts TCMT1.8 inserts for like $5ea.

Doesn't chamfer it makes jagged edges like a chainsaw.

Think of this as a palm size router. And the cutting heads that it comes with are not sharp or hard enough for stainless.Just for warning, I don't think this is a fault for them.More or less for me but yeah

The first issue is that it comes with no tape to ensure there is no air leakage. The second is the bearing won't come off so you can't switch the bearing which you'll need to do if you want to do a radius instead of a corner. Third, you can't adjust the air outlet so it sprays towards anything you're chamfering. And it just feels cheap overall.

Great little tool tried it and quite impressed. The air fitting is a what ever type screw so I welded a 1/4 inch pipe fitting on to it so I could put one of my quick release fittings on it besides that it works great.

Excellent tool for deburing/bevelling. I use it on Aluminium and it produces an excellent finish. Does require several passes for the smoothest finish. Ups the level of my products. Appears to be well made.

I used this product to chamfer for weld prep. The second time i used it, the cutting head came removed from the motor shaft internally. Never once stalled it out nor dropped the tool. Junk
