Mars-Rock Carbide Burr Set Compatible with Dremel 1/8 Shank 20PCS Die Grinder Rotary Tool Rasp Wood Carving Bits Accessories Attachments Metal Grinding Engraving Cutting Trimming Porting Double Cut

Worked fine on steel and aluminum. Cutting edges have held up fine. For the price point, hard to beat.

These are very good quality. Worked well grinding on softer metal than the bits.

These carbide burrs are fantastic. They cut through metal like butter and are of high quality. They come in a very nice case as well. Great value for the price.

They are much better then i expected

These bits are very sharp and very easy to use, a must have in your shop to get the job done. I would recommend this product for anyone who has a shop. Great value for my money.

Use them in a resto shop. Have tossed them their fair share of abuse and they are holding up so far.
