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

Poor quality

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.

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

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 RPM 10.4 in/min feed .036 depth of cut .050 step over Climb cut

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

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

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

ok

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