Hakkin 10Pcs Tungsten Carbide Double Cut Rotary Burr Set 1/4” Shank Die Grinder Drill Bits for Dremel Accessory Wood Carving Tools DIY Woodworking Carving Drilling Metal Polishing Grinding Engraving

These are definitely worth buying.. I found them to be really good value for money. I was thinking about buying just a few or the burrs I thought I needed as opposed to this set of 5 but I’m so pleased that I didn’t because it’s good to have a variety since you probably don’t know what burrs are best suited for the job in hand.. best to buy the set of 5…Excellent value for money

Amazing bits, nice and sharp and durable. Mainly used on plastics which they have 0 issue and thin metal. Can’t go wrong for the price

Good size and nice weights. Removes wood extremely well probably could do with a faster device than just a standard hammer drill. Not tried it on metal but can't imagine it would be any worse.

I bought these more in hope than trust to try to get a seized bearing shell out of its seat. The burrs when used with a Milwaukee drill worked really well despite not spinning as fast as a rotary tool would spin them. They got me out of a bind and still look and feel just as sharp as when I bought them. I've no regrets about buying them at all and they will be a useful addition to my tool rack.

Thanks a good product works fine as diy tool

I have only just discovered burr bits for my metalwork. They are very effective at getting into tight inside corners to clean up welds and will easily remove stubborn spatter but you must be careful. The very attribute that makes them so effective is also the reason they can be really quite scary to use. They bite and grab at the metal unless handled very carefully and will instantly jerk and snatch the tool. Fingers must be very actively kept clear of the burr which will happily grind to the bone in an instant if out of control. All this being so I still really love using them!

I bought these after getting frustrated with the grinding stones I got with my air die grinder.I was trying to clean up some welds in a tight space where my angle grinder just can't reach. The grinding stones were very slow at cleaning up the weld area, but these burrs were just the thing; they removed the excess weld quickly and cleanly using less air in the process. What took me an hour to clean up before with the grinding stones took 10 minutes with the burrs.How long they will last, I don't really know, but if you let the tool do the work I would think they would last quite some time. There was no visible signs of damage or wear to the cutting faces after cleaning up several welds. As with any cutting tool, if you use too much force, they tend to break.These are definitely designed for die grinders, you need the grinder's speed and power for them to work efficiently, I don't think that using these on a drill would give you the same performance when working with steel; although you may get away with a drill on softer materials such as wood, plastics, or possibly aluminium.Overall I am very impressed with these burrs, especially for the price.

Well I was not expecting it to grip that much but it nearly knocked my socks off .... they are extra gnarly for what I was expecting.. should be a rating of 8 grr's which is enough to vibrate my eyeballs and give me a mild case of vibration white finger.
