Carbide Burr Set 8pcs with 1/4''Shank Double Cut Solid Power Tools Tungsten Carbide Rotary Files Bits for Die Grinder Metal Wood Carving Engraving Polishing Drilling Grinding Milling Cutting

Well worth the money. Cuts steel and looks new when finished. I’m sure it will gum up on aluminum like a file or grinder but perfect for steel

The round bits work better than any drill bit I have ever used, bore a hole with them as a pilot hole then start with your drill bits, the small round bit bored through 1/4" steel plate with ease

Outstanding product where many others failed.. it cut through a tire stud that was stuck better then drill bits could.

Grinds good, not industrial quality, but great for anything the homeowner is going to toss at it. Ground down exhaust welds and still sharp.

I was skeptical at first when ordering. Fastenall charges an equal price for only one of these bits. I decided to try it and have been IMPRESSED! I used the set on 3/8" thick steel to widen a few bolt hole openings in an elevated catwalk frame and it did the job in less than a minutes time. It works great for opening up a door strike plate without removal of the plate and the price is spectacular. One caution though; My friend needed a set so I got him one, but he ended up bending the shafts on two of the bits. It is very important to hold the drill or router tightly when using these bits because they really grab the steel when grinding. I still have all the original set bits in my kit.

Wry sturdy, bits are sharpe and easy to use and you get all sizes. Great design

Great product great price did the job perfect

I broke off a tap in my steering knuckle while trying to repair a broken bolt. I couldn’t drill it out or break it out and was about to drop $600 on a new part. I saw a video on YouTube where a guy used a burr tool to remove the tap and decided to give it a try. I can’t tell you how easy it was to remove the broken tap! The burr chewed it up like it was soft plastic. I was able to get the old tap out and carefully re drill and tap a new thread in the knuckle and saved myself from a hefty expense!

Awesome product, works perfect

These work great, well made.

Great value for the money considering I am using it for commercial use.

Great selection and excellent quality

Good
