Worked great. I'm very careful at how much I take off with each pass, but did not disappoint in the least. Used it to make square mortises in an arts and craft style stair railings.

I use this very frequently, hasn't dulled yet and produces a clean cut as long as you use it appropriately. Don't forget that your first Depth of cut has to be long enough to engage the downcut portion if you are wanting to take advantage of that feature, if not you are just going to be using it as any other upcut bit.

I bought a pack of 5, and one has already broken after the second use. I made no changes to my CNC settings from using my Amana (46225-K) bit previously. By no means am I endorsing Amana, just haven't found an alternative. I'm currently using the 2nd bit but I've already noticed it leaving a burnt residue on the backside of the wood...hope I got a bad batch. I guess I'm going to have to test their customer service as I'm wanting to return these inferior bits. Update: Today is 27 May 23 and the 2nd of 3 bits used has broken. I bought a pack of 5, so 2 more to go. The problem is when you leave your job unattended and the bit breaks, now you have a destroyed piece of material. I don't know about you but I don't like to babysit my CNC machine. Update: 31 May 23...contacted them and they swiftly gave me a refund. Customer service is excellent. I will give the same product a chance and purchase again to ensure I did not get a defective batch.

This bit worked very well for cutting fairly deep half lap joints. It’s arguably not the finest bit on the market but it’s 2” length overshadows any other disadvantages the bit may have.
