Review: I am impressed - I have to say for a 1mm bit. This is pretty good. It is the 1mm titanium coated but in this video. These helix bits successfully carve hard purple heart wood, where normal bits failed
Review: Good for hobbiest with no money - I purchased an inexpensive CNC router. It only came with one type of bit. That type of bit is not one I wanted to use. I purchased these because they were inexpensive and I am new to CNC routing machines. I received a variety of bits and did some testing. They work well for the ametuer that is learning and doesn't have a great deal of money to buy the expensive bits that everyone on YouTube is pushing.

### ⭐⭐⭐⭐⭐ Good for hobbiest with no money
*by A***R on March 25, 2026*

### ⭐⭐⭐⭐ Grinding tolerance
*by T***K on October 12, 2024*

The corn mill bits work great from wood to mild steel, on a router or milling machine the flat and ball end mills work about fine for soft materials. On the outer edge of each flute of the 2-flute mills, there is a continuous band of unground steel, which should taper inward- this causes the tool to rub slightly. There is visible variation in the depth of the grinding, causing the unground section to be sized differently along the bit, and even between multiple bit there is a visible difference. I did find two ball end mills that had good edges near the bottom, which I'm pleased with, I just have a hard time understanding how you get so much variation on such a small scale. You get what you pay for, and for what you pay for this is a decent set.
