Item arrived and was as described in the listing. I have a small table top cnc machine that I use for small signs and crafts. I installed this bit in that CNC and have been cutting through 1/2" thick softwood with it and have had no issues. It does a pretty good job at expelling the chips and keeping them out as it moves along. A decent little bit.

The AYCHOLIZ ball nose end mill is being used as the replacement to an uncoated 2 flute big brand version. As anticipated, the coating and 2 extra flutes outperform it's competitor. The AYCHOLIZ mill cuts well in aluminum and even plastics. Used only for finish work so far, the lower cost AYCHOLIZ is a dependable and efficient choice to replace a pricier alternative. Will continue using!
