SpeTool 1/8 End Mills for Aluminum 3 Flutes CNC Spiral Router Bits for Aluminum Cut Non-Ferrous Metal Upcut 1.5 inches Long 5 Pieces

These are great for my CNC milling machine and CNC router machining aluminum. Finish on my milling machine is superb, I run them around 4800RPM and at recommended feed (as per GWizard calculator for the width and depth I need) and have not broken one yet. On the router I run around 10k RPM and 25-50% of recommended feed rate, finish is not as good on side walls due to lack of machine rigidity, not broken one yet cutting 1/8 plate aluminum. Definitely will buy again, I have other larger SPE tungsten end mills and they all perform very well.

I 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.

These bits work great on desktop CNC machines for milling aluminum. For the price, you get 5 bits which is nice. The only downside about these bits is that they are uncoated, so they do wear out relatively quick when compared to a coated bit. But other than that, I have no other complaints. I was able to get very smooth finishes from facing, after a finishing pаss of 0.002”.

Cut right through aluminum easily as long as I dont do something stupid in my g code.

Cut aluminum. Worked good. Cant beat them for the price

Perfect for the price

Poor quality

Best for the money can’t lose on this i will buy again

Im pretty happy with these cutters. They held up well on softer alloys with lubrication, and were able to get through hardened alloys with some finessing of the toolpath. Overall, they got jobs done and I ended up with a nice finish. Pretty good for the money, especially since Im an occasional user and dont need to invest heavily in my hobby tools.

Worked well, as described. Weve cut 4 gearbox plates and a bunch of other 1/4in alumimum with a small router and these bits.
