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

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.I've 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”.

FWIW, I used it in my CNC mill (sticking out 1" from the collet) with the following feeds/speeds and it cut perfectly:3000 RPM10.4 in/min feed.036 depth of cut.050 step overClimb cut

The media could not be loaded.  Needed a small endmill to make special cuts on a project I was working on. Cuts aluminum like butter. Would recommend.

Milled several inches of 1/4" deep slots in aluminum, worked very well and didn't break.

I"m 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 I'm an occasional user and don't need to invest heavily in my hobby tools.

These 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!

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