Tungsten Carbide Burr Set Die Grinder Bits 1/8" Shank 20Pcs - Double Cut Rotary Burr for Metal Deburring, Finishing, Carving, Grinding, Polishing, Engraving, Drilling

So far these have worked great at shaping/cutting plastic, wood, aluminum, and stainless steel - and they still feel sharp. The well made, attractive case is a great bonus. I plan to put more holes in it to hold other 1/8" bits.The last 'Carbide' bits I purchased on Amazon appeared to be dipped or sprayed with carbide, and they wore out during the first use. Conversely, these bits are the real deal!!

I think this is about the first review I've ever written but these worked so good I had to. I used them w/ a cheap harbor freight air die grinder (the bits cost more than the grinder!) and they worked incredibly well to grind some welds I couldn't reach w/ a grinder on a tractor attachment that was built incorrectly. I had tried some harbor freight ones first and they were slick w/in a minute and wouldn't even touch the weld. These worked fantastic, metal flying w/ the first touch. Took me probably 30min of almost non stop work using only 1 bit and it still looks new. Now I have 10 bits for what 1 cost at the welding supply house. Would they last in a production environment? I don't know but for farm use they're perfect.

I guess I should have read the small print, but these are not as large as I had thought they would be and may not work for the task at hand. I do like the packaging, the little wooden box that holds them, and they certainly are sharp. I’ll use them on projects that require detailed work.

Great Product. Great seller!!!! They actually know that 3mm is not 1/8 inch. 3.175mm equals 1/8 inch. Most sellers have no clue and totally lie that their product has 1/8 inch shank size. I highly recommend this seller for being honest and selling a quality product!

Really nice burr set. I've cut SS, mild steel, and aluminum with these and am really happy with their performance.

Even though I haven't had a chance to use them yet, they appear to be of high quality, very sharp, and built to high standards. I really like the wooden box/case that they came in, it will definitely keep me from losing them individually.

Works like a champ on cast iron

I've had a set for years, but no holder, so a couple went missing. Now I have them all in order and room to hold my old ones in one spot. nice quality tools.
