HSS Deburring External Chamfer Tool for Metal - Quick Release 1/4" Hex Shank Drill Bit 1/8"-3/4"(3-19mm), Thread Repair & Countersink Bit for Stainless Steel, Copper, Aluminum & PVC Pipe

One of those tools you think, Why am I wasting $ on this accessory. Already fixed multiple threaded bolts faster than digging out a tap. Worked perfectly for custom threaded rod. Keep the cardboard sleeve. Device could have laser engraving with max rpm on the outside diameter. Works at slow speeds (only noted on the back of the packaging).

I had over 350 3/8" low carbon steel bolts to cut and chamfer. This part held up through all of them, and still has some life left. I am thoroughly impressed.

Not as clean a job as a band-saw would do but hey, these are a fraction of the cost of a band-saw. I use this tool to clean all-thread and it does about a four-star job. I would recommend for small jobs absolutely.

It is a very handy tool to have.

I had been rounding off the ends of bolts on the grinder and then finishing off on the wire wheel, but this is much faster and doesn't wear my grinding stones on evenly. A little cutting oil as suggested makes it fast and painless. Just use common sense and don't apply too much pressure initially.

Love it! I use a lot of all thread cut to size. Cut the whole lot, de-bur, go to work. Without being 20', hanging in the sky, and have try to file to start nuts. Start your nuts easily!

Great tool

It works ok but there better for the money spent
