Review on Amana Tool 51419 K Carbide Spektra by Eddie Simpkins

I just finished cutting 1/4" cast acrylic (aka Plexiglas) for over eight hours and this cutter is still perfectly sharp With standard full depth milling (single pass, 18,000 rpm at 150 ipm) the cut quality was very smooth With pocketing (or face milling) the cut quality was quite normal, which is a typical quality for an O-groove. Please take a look at the photo I've added This Amana cutter was $35!
