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

Milled several inches of 1/4 deep slots in aluminum, worked very well and didnt break.

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

I have been cutting 1/9”aluminum plate for a couple days . Tried these bits as it said aluminum so cuts worse than my other bits and running slower broke 2 bits in 10 min didn’t make it through first pass so I’m done these won’t work for me .

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.

ok

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

Well made end mills. Able to fine cut names in heart boxes for Christmas gifts.

Cut 1/8 6061 sheet with them. Cut nice and have lasted 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.
