CZS 2 Pack HSS Hex Shank Deburring Tool for Drill Bit, 8mm-19mm, Stainless Steel, Hardened Mild Low Carbon Copper, Brass, Aluminum, Fiberglass, Wood, Plastic

I've read reviews on this and like products and wasn't real sure what I would get. Well a project came up and I needed to use these. I popped it into the drill and applied light pressure and it did a great job. I deburred 1/4 bolts which bottomed out, so this would be really the smallest size. But it did exactly what it said it would do. I only did 8 grade 5 bolts so I don't know if they would cut grade 8 or stainless or how many times you could use it. But for the cost I'll just buy another set when they get dull.

Helped very helpful durable

They work but don't seem to last long. After about five 5/8 all thread rods they seem to go full and no longer make good edges. Still worth buying though. I'm glad I got them.

Great product

The seller provides some numbers but from my experience those are outright wrong. And another important parameter is missing from the description. So first, don't even think about #8 (~4mm) bolts, even 5/16" (M8) are barely scratching the blades. Second, forget about short bolts, anything shorter than 1" won't work. So, the product is of very limited usage.

Description says "Fitment Bolt Tube Size：(6mm -28mm)" but will not chamfer a 1/4" bolt which is larger than 6mm. The bolt goes down below the chamfering cutters so no way for the chamfer to happen. Note too that I could barely get it to chamfer 8mm rods... it barely cut the tips. Returned. Do not buy if you're hoping to chamfer smaller rod/bolt sizes.

I do a lot of work with Yuna strut and threaded rods. I have used this tool so many times I can't count. It works great. But not screws right onto the rebar like it's a bolt right out of the factory. I would recommend this to anyone. Thank you so much for being with us

By these stick them in your drawer and when you need them you'll have them
