Asieg Tool 20 Pcs Carbide Die Grinder Burrs Bits 1/8" Shank for Dremel Milwaukee Metal Grinding Wood Stone Steel Carving Cutting Engraving Grinder Kit Attachment Rotary Tool Accessories Sets

Great value! Work great. Good selection of different sizes and shaped tools.

These hold up well and I have used them on carbon steel and stainless. They are small and can fit in tight spots. I used them in a Dremel and drill.

I have used the hell out of this set of burrs since I received them, and they are all still razor sharp. They have so many more uses than I'd originally thought about. They are much more maneuverable because of their small size. Just a reminder: because of their size, don't forget to choose a high enough cutting speed

Originally I was concerned about the statements made about these bits. I’ve purchased other “carbide” rotary bits that have just worn out with minimal use. These actually work really well and so far have lasted a good while. I just spent the last 2 hours grinding out a spot in a Damascus axe blade to inset a guard for the handle. These bits made an otherwise unobtainable goal done quick and easy. Absolutely worth it, not one overheated or detached from the shaft and all still are plenty sharp and ready for the next job.

First, the seller is awesome! The review is for the product itself. I spent a decade grinding on nickel and cobalt based aerospace alloys, so yeah I know a good grinding bit when I use one. These took a while on 4140 steel, should have been like butter. They got the job done, and the assortment was VERY nice, I could do all the radiuses I needed, but it took a while. Three stars isn't bad, just "average", the seller gets 5 stars.

The quality is good and performed as exactly as I needed them too. Plus with all of the different head I always had exactly why I needed to get the job done. Plus the price pint was amazing for how many you get and how well they work. They carved the wood well with out being overly aggressive. I would highly recommend.

These work great for small things

Excellent, Exactly what I needed, Very sharp to work as they should!
