JEEKVISENJEEKVISEN Tungsten Carbide Burr Set 1/4" Shank 10Pcs Die Grinder Bits - Double Cut Rotary Burr for Metal Deburring, Finishing, Carving, Grinding, Polishing, Engraving, Drilling

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.

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.

Cut aluminum great staying sharp. Great selection of heads

Good verity of birds

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!

Awesome burrs extremely sharp and work awesome for the price.

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.

Works like a champ on cast iron
