I recently downloaded this app and it is exactly what I was looking for. It has all of the commonly needed info from the machines handbook in one easy to navigate place. I would really like to see the addition of Cobalt as a cutter material in the Machinability & SFM data function. I primarily use Cobalt drills when drilling and having the appropriate SFM with respect to Cobalt would be helpful. I appreciate all the hard work that y’all have already put into this app and even if Cobalt is not added the app I still well worth the money.
