20PCS 1/8 Shank Tungsten Carbide Burr Set Diamond Files HRA85 Rotary Tool Accessory Kit, Drill Chucks Accessories for Dremel Rotary Drill Air Die Grinder, for Metal Polishing, Wood Carving

These 1/8 inch bits work better than I expected,for their price.

I’ve only used one of the bits from the kit so far but it has held up cutting slots into 20 pieces of 1/16” steel so far.

Bought this set to replace a busted carbide Dremel burr for a project I had grinding steel. These replacement bits certainly did the job, and then some. The carbide Dremel burr broke on the first piece, these however literally stopped the tool when they got stuck. The bit looked unused when I finished. Good stuff.

Didn't look exactly like the pics with a gold portion so not sure I got exactly what I ordered but they got the job done well. Ground off portions of a steel PC case easily, no visible degradation on the bit afterwards.

Just what I was looking for for my dremel tool
