Carbide Burr 1/4" Shank, SB-5 Tungsten Double Cut Rotary Die Grinder Bits - Cutting Burrs for Milwaukee, Dewalt and Makita Die Grinder Accessories - Wood Carving Metal Working & Sturdy Storage Case

Didn't actually know these existed, duh ! So having read the reviews and needing one for a scaffolding bracket, long story (Christmas tree topper stabiliser), I needed to remove a lip from a scaffolding bracket, with my trusty Dewalt and one of these, in next to no time lip pretty much gone and the head still sharp if I ever need it again. Tried using it in several ways but found a lower speed and don't press too hard appears to work the best, the Dewalt chuck would become loose so had to retighten it, but that could have been me. If you need something grinding in smaller spaces, these are worth a try. I would purchase one again should I lose this one. I did purchase another brand at the same time in case this one failed, but not necessary.

Use this product to do my wheels. I had bought 2 different ones that broke within 5 mins. I only used 1 for all 4 wheels from this supplier. Well recommend

Better than expected will grind hardened steel

did the job

For odd job there ok, not tough or durable , chip easily . Quality not quite there

These cutters are very sharp and remove a lot of material in a short time. The one I used held up great, and looks like it will last for a while.

Worked like a charm. needed to enlarge a hole on 1/8 hardened steel. 10 minutes i was finished.

Muy buenas limas rotativas buena calidad gracias taita oor fabricar lkmas rotativas muy buenas

Product is good for working on steel and or other hard to shape items I personally use it on my coilovers,very sharp and easy to use! It's definitely a good value for your money!

Bought these to do some heavy stock removal and milling on a rifle receiver. I figured for the value a 3 pack was a better option then buying a single bit, especially if they dulled fast or broke easily. However after completing the job I only opened one pkg and it’s still just as sharp as when I started. The demo video showing this bit going threw a wrench is very accurate and it certainly can remove metal at a fast rate when used properly. When ever I finally manage to go through these I will be buying the multi bit set next. Definitely a good value and quite durable
