THORVALD Deburring External Chamfer Tool with Tungsten Carbide Blade - Deburr Tool for All Thread, All Metal Rod, Pipe, PVC, 3D Printing - 1/8" to 3/4" Diameter (3~19mm) - User Guide + Video Tutorial

This works well, I use it frequently.

I used this tool to deburr leaf spring u-bolts after swapping out a rear end. The u-bolts were brand new 1/2” fine thread grade 8. After cutting the u-bolts to length with a cutting blade on a 4-1/2” grinder I ran this tool around the ends using a cordless drill. It worked fine and I was able to get a nut started on each end without too much trouble. Looking at the blades in the tool I didn’t see any damage or dulling at all. I’ve no complaints.

Save your fingers and frustrations. I never need to use the sander or my deadly grinder to mend the threads on bolts I cut down to size. The reaming function works on trimming burrs from small pipe as well. Thorvald seems durable and well made. And the quick connection makes it easy to use. Update: Having used this for a while now, I have become disappointed in the tool’s performance. It is very difficult to use on smaller bolt sizes (<1/4”) and is much to deep to use on short bolts as well (<1”). Also, it needs to be tightly secured in a clamping chuck as it wobbles too much in a quick connect chuck.

Purchased this one and a less expensive one from another company. This one is working like a champ. The cheaper one broke on the first day. I will be buying more of these even though they are more expensive.

This is not meant for repeat commercial usage. Use oil, repeatedly * as would with any machining of metal * slight pressure, med speed or less on drill. I used this this morning on 10MM X 30 Stainless bolts. Worked fine. I used 3 in one sewing machine oil. Any oil will work ( not sure about corn or olive ) do not drench it, just a few drops. Will keep cutting blades sharp and last longer. Before cutting, run two of correct size bolts onto bolts you intend to cut. Twist them together. Clamp vice on those bolts. Go slow and steady, do not over heat cutting blades. Wait for bolt to cool Remove the bolts they will straighten the threads. Run em over the end of bolt a few time. Great price from Thorvlad. if can drill hole in metal with drill. You can use this . When done chamfered, clean bits of cut metal from the threads with wd-40 and paper towel. Otherwise bolts will bind as twisted. Use same wd-40 or penetrating oil to clean the Cutting device. ALWAYS USE PROPER PERSONAL BODY PROTECTIONS ( SAFETY GLASSES, DUST MASK, ETC.). VERY GOOD INSTRUCTIONS COME WITH CHAMFER DEBURRER. GREAT PRODUCT ESPECIALLY FOR THE PRICE.

It works great. Good tool.

Did not last more than 5 min.. the weld broke after two rods
