MeseeSet of 4 Tungsten Carbide Rotary Burrs, 6 Inch Long Double Cut Rotating Burr with 6mm Shank Files Rasp Bit Tools Kit for DIY Woodworking Metal Carving Polishing Engraving Drilling

really work well. the cylindrical ones are the most useful, but all are sharp and remove wood or metal. there's no blunting in evidence so far

For the price, you can't really complain about these. They cut their way through 3mm mild steel easily and without any effort on my part. The length of the burrs means trying to hurry them is a bad idea. Let the tool do the work. How long will they last? No idea, at this price point you wont be handing them down to your children, let alone grandchildren.

Good value for money

Nice and sharp, very long though and will wobble around unless under load. Slow speed operation only!!

Would avoid this item as it is too thin and can be dangerous at high speed since there’s too much movement on the tip

DO NOT BUY! This product is extremely dangerous. They bend through centrifugal before even touching the material you want to remove. They cause the tool to vibrate extremely to the point you can barely hold it,I damaged items close to my work piece due to it shaking so much until I could unplug it.It’s caused an injury to my wrist and cost me money in damaged items.

Exactly as description
