Q: Their milling cutters are cheaper and what is the difference between the expensive ones from other brands?

I have been using their products. Although the price is relatively cheap, the quality is not inferior to the brands on the market. It is very good and the quality is great! I've been using it for over a year with no quality issues.

Q: Inexpensive, don't know how well it works？

When I first saw the price of MNA drills, I thought they had to be very cheap, "disposable" drills, so I bought them with that mindset. I was wrong! They stand up to what I put in front of them. Even teak and brazil cherries make beautiful, smooth, even cuts - no burn marks. I highly recommend the mna bits!
