Serplex® Tungsten Carbide Rotary Burr Set for Dremel, 10pcs Carbide Double Cut Carving Burr Bits with 1/8" Shank Rotary Tool Accessories for Woodworking, Engraving, Drilling, Steel Metal Working

Tried it on thick metal, wood and plastics. Impressed with the performance and quality of these. After such rough use (that it's meant for), it's still intact and sharp. Once you clean it after a job, it looks like it was never used.

Product cost is compatible. Fast delivery.

Good quality

working good for wood and cement but not good for Marbels and tiles.

Not a single drill bit in this set worked properly. The product claims to be titanium-coated, but the cutting edges become dull very quickly. I was unable to drill effectively even through basic materials. I thought that because it was more expensive than some other options, it would be a better-quality brand. Unfortunately, the quality is extremely poor. The drill bits feel cheap, perform poorly, and do not last. I would not recommend this product to anyone. It is a complete waste of money and does not live up to its claims.

Good product it polich arc welding very easily but size is very small

So far so good. Using it on wax, they are working pretty fine. Size is appropriate as well (subjective to user requirements). Quality seems good and the cuts are very well defined to do the job right

It is not strong as the image
