Review on 🪚 YUFUTOL SF-3 Tungsten Carbide Burr Double Cut Tree Shape Radius End Rotary Burr File, 1 Piece, 3/8” Cutter Diameter x 3/4” Cutter Length, 1/4’’ Shank Diameter by Eric Dailey

I can't believe I got this quality drill bit at such a low price. This thing cuts through aluminum like a katana sword cuts through butter. manufactured by this company. Bottom line, they work. You can even use them on variable speed drill presses. Thank you Revine. This ridge seems to be built for eternity. Cut. I use a dull front belt cover on a 1250 Harley Davidson. I use it to sample from dremil bits to burrs, from these small dremil engrave bits to sample this burr, at low speed it all cuts like I said the katana threw oil. I have found and own several. Thanks Revin I can't wait to move the intake manifold cuz this thing works. I already have a micrometer. So I can move my distributor in about an hour.
