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

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

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”.

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

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

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!

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

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.

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.

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