ORXPLUS Tools Deburring External Chamfer Tool, Tungsten Blade, Deburring Drill Bit, Remove Burr Tools Suitable on Stainless Rod, Thread and Pipe for Fit 1/8"-3/4"(3mm-19mm)

Use oil on tool, slow speed and will work great.

What a surprise to use a cheap tool that actually works. Cuts like a hot knife through butter. Nuts thread on perfectly. Used on m6 and m10 bolts.

Not as sharp as I would like but with the correct amount of pressure it works pretty well.

The de-burring cup is an actual 3 point cutting tool that utilizes HSS to shave the end of bolts, bar stock, etc... so, if you come at it cranked up to 11 and expect good results you’re going to do some damage, or have a bad day. Anyone who’s drilled metal, or used a single point cutting device (lathe, fly cutter) knows that speed and feed is the name of the game. Start on a slower speed, and apply generous pressure, and after a few times you’ll get the feel for it and be able to yield phenomenal results. I’ve used it on mild steel, and stainless, and have had excellent results. I don’t like that you can’t replace the HSS inserts, but I realize for that option you’d end up having to completely redesign the device. Also, the little indented areas where the chips are supposed to collect does get somewhat clogged, but I think this feature is more like a chip breaker, not an area for shavings to reside long term. I ended up using a metal pick I have to clear them, and it worked great. So, moral of the story, if you’re a wood working screw jockey who expects tools to yield to your will you’re going to have difficulty with this cup. But, if you come at it from a machinist perspective, you’ll wonder why you wasted money on the $10 cheapo infomercial style debuting cups.The chamfer I LOVE!! I’ve had issues with the Irwin/harbor freight chamfering tools. This is the solution to your desire to create a chamfer, but again, name of the game is low and slow until you find a good speed and pressure to apply. Be thoughtful, and you’ll love it. Buy once, cry once boys... I know, terrible phrase, but it’s true.

I had to cut down the studs on my rear axle as the ARP ones were too long to use with closed lugs nuts. The was able to go through all ten studs and chamfer down the sawed off end on all ten studs. I used a regular cordless drill set to the lower speed setting (1 instead of 2 for my older Dewalt) and the tool worked its magic on the ends.I'm not sure how many more studs it would have in it, but I know that it went through ten hardened studs with great results and still has material left in it for more work down the road. It's in my drill bit drawer now for use on the next round of all-thread, studs, or bolts I need to chop down and chamfer.The pictures show the first stud and the last stud I used this on as well as what the starting point was for each stud.

Great tool for tapering the ends of all thread rod, bolts, solid rod, steel & copper pipe (aluminum pipe is tricky). As others have said, DO NOT USE AN IMPACT DRILL!!! A small hand held battery drill is best, start at low speed and press lightly until desired taper is achieved. Hit it straight on, do not walk it around in a circle. If there is a burr on the work piece, say a cut off tip, grind or file it off first. This will keep the tool from giving you an off-center taper. I’ve used mine a dozen times w/o problem, still sharp.

I see this to smooth the ends of cut off bolts. I’ve used it on bolts 1/4” and larger. Gives nice smooth finish ready to easily thread on nuts.

It worked very well for about 30 or so uses. The chuck snapped and now it is useless. If you do purchase this I'd advise against putting it in your impact. Use a drill instead. Not impressed with the quality *update * seller contacted me and replaced item for free. I appreciate this level of customer service
