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

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

ok

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

Poor quality

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!

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

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”.

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.

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

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.
