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

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

I’ve been hogging out aluminum on my Sainsmart Genmitsu 3020 for months now and I’ve never broken a single endmill. Solid product.

It works great on acrylics. But not aluminum. It broken after I used it on aluminum.

Yes Great product worth the money and has done its job 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.

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

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.

I am a avid hobby machinist and generally use these in my sherline mill. I have tried almost every brand of end mill and primarily use YG1 Alu-power and Gorilla mills, which are some of the best you can get. These 3 flute end mills are absolutely razor sharp and as you can see in the picture I cut my finger pulling it out! They cut like butter in steel or aluminum and for me personally the 3 flute is the best of both worlds as it cuts fast like a 2 flute with good chip evacuation but leaves a much better finish, with a ridgid mill you can expect almost mirror like finishes. One of the best parts is you get 5! 5 end mills for less than $30 and they are perfect, if you are looking for razor sharp and long lasting micro end mills then these are a no brainer and I personally bought 20 of them which will last me forever.

ok

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