40pcs End Mills CNC Router Bits, 1/8" Shank CNC Cutter Milling Carving Bit Set Including 2-Flute Flat Nose & Ball Nose, Nano Blue Coat & Titanium Coat, MC40A

Arrived on time

This is a good variety of small bits for a reasonable price... I broke a couple but they are tiny and I was driving then pretty hard. The seem sharp, did a good job and are holding up very well.

For the price, and as a newbie to the cnc world, these are great. They are cheap enough that you can afford to make some mistakes and break a few. I've found with these bits that slower is usually better. As many have mentioned, they do not come marked with the sizes however, a cheap set of calipers easily fixes this problem.

The media could not be loaded. These set of bits are definitely worth buying. The only downfall is they are not labeled. I've used the .8mm bit to carve in aluminum. These are easy to break so I set the depth pass at .001" on my xcarve machine. I highly recommend and I will buy more for extras.

Works good and they last long

Excelente. Todp tal cual.

These milling bits work great for non-metal materials like wood, plastic, or composites. However, when it comes to cutting aluminum, they fall short. While the description claims they can handle aluminum, in practice, you’ll get one use at best before the bit dulls or wears out. If you’re planning to cut aluminum, look for higher-quality bits specifically designed for metals. For non-metal projects, though, they perform well and are worth considering.Bottom Line:If you’re sticking to non-metal materials, these bits are fine. But if aluminum is part of your project, look elsewhere for a more durable solution.

So far these are working great!
