> 24 hourThese bits are absolute junk. They break at the slightest side load when cutting aluminum. Might be good for foam or soft wood, but NOT cutting hardwood or aluminum. SAVE YOU MONEY!

> 24 hourI just got started using my SainSmart desktop CNC but needed an Upcut End Mill for an aluminum project. These end mills have done a great job chipping away at my project. The construction of the desktop CNC is a bit lacking so I can only cut 0.005 in depth per pass. Ive run one of these end mills for 100hrs or so will no real change in cut quality. I did break one end mill when a part came lose during a cut but that was my own fault setting up my material improperly.
