CNMG 431 WNMG 431 TNMG 331

arrived quickly and was as stated. I have only cut a little with them but seem to be working well.

I have spent thousands on different inserts and unless it's for a very specific purpose the difference is almost non existent. These inserts perform great and leave an excellent finish. Do a good job hogging out material when you need to. Keep your finish pass at .010-.020 DOC and you will be very happy. I know I am.

They work great for manual lathes, Not the best for cnc

These things are great on stainless, tool steel, 4140, and a few other things I've thrown at them. I also the insert holders made by the same manufacturer, and they are a great value. from what I hear, the edges are not lasting as long as some of the industrial grade inserts, but with these being so reasonably priced I'm not worried about breaking these when I make stupid beginner mistakes.

These are as good as the brand name. I have cut mild and tool steel with great finishes and long life on the tool. For the price you cannot beat these. You could not but three name brand inserts for the price of thirty of these

The product did exactly what was advertised and lived up to my expectations. I am satisfied the product did what I wished and will most definitely purchase it again in the future. If something does the job expected what is there to complain about.

Thank you.

I’m not using them for production I’m just a hobbyist and for the price difference they work great for me.
