Hi guys,
A face mill I purchased from Amazon a few days ago showed up today and first thing I dragged it into the shop to measure how well-placed the inserts are. It's a 2", 90-deg R8 unit that employs 5 APKT inserts. Measurements indicate there is about a 0.001 variation in the depth of seating across the insert set. I have no way to know if that's a good number or not. My instinct is that it's so-so but again, I don't have the credentials to do more than speculate. If that amount of variation is questionable to someone with face-mill experience, I'll send it back and wait until something with more definitive lineage appears.
This was more of a pushup than I thought it would be. My sole recommendation for this was the Amazon recommender system, which I presume skews toward the inexperienced end on cheap tooling. This tool did have more "endorsements" than I could find for anything else. It's not what I wanted other than it's a face mill... my research lead me to prefer a 2.5" (max) 45-deg SE indexable with a high positive rake but once that theoretical objective had been fixed, I was unable to find much of any data that pointed to a particular implementation. 1 or 2 semi-passing comments here/there but nothing that seemed worthy of making the commitment. What say you fellow Romans? Thumbs up or down?
