ORXPLUS Tools Deburring External Chamfer Tool, Tungsten Blade, Deburring Drill Bit, Remove Burr Tools for Fit 1/8"-3/4"(3mm-19mm)

I've never used one of these deburrers before, but this particular one showed no visible wear after deburring/chamfering both ends of 8 lengths of Ø6mm stainless steel round bar. I followed the recommendations for speed, used cutting lubricant, and held the bars firmly in an engineers' vise. There is only one contradiction I noticed. The tool works best if the end of a round bar is free of burrs! Start off slow and be prepared to stop and start again if your drill jumps around a bit. I imagine the deburrer would work best if both the bar and tool were mounted in chucks on a lathe, but if I had a lathe, this tool would be unnecessary.

The blades chipped on first use. I used it on threaded rod 8.8 and amazon refunded me

A+

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 recently got into pro-press pipe fittings. Sometimes when I use my autocut pipe cutter it mushrooms the outside of the pipe. You can use a manual chamfer tool for this, but it's time consuming and tedious. I tried this and at first was getting overly aggressive results.....(I put it in an impact gun). I then put it in a standard drill at low speed and light pressure and it does the job beautifully! Time and wrist saver. Works well for me!
