SpeTool5Pcs 2-Flute Square Nose Carbide End Mill 1/8 Inch Router Bit with 1/8 inch Shank CNC Machine Tools, TiAlN Coated

Hard to tell from the photo, but the cut was clean with minimal visible tool marks on the bottom or sides when cutting 6061. This was the primary reason for purchasing, so I'm satisfied.For what it's worth though, tried to use one to cut acrylic. While it did cut, I had to pause the job multiple times to snip off excess material from the tip of the endmill. Probably better to stick with cutting metal using these.

I bought this to subtract some material from a piece of forged aluminum. don't have a lot of experience with the material, so i bought a few different end mills just in case something gave me trouble. in my experience, i thought i would use this to plunge cut and a 3-fluted or more for everything else. this thing blasted through the material. it was so sharp and rigid that even 1.25" deep, it never tugged or made the part slip, despite it being in soft jaws and a manual machine with no power feeds. I never took any of the other tooling out of the packaging. in hindsight, i probably didn't need to buy carbide, but it's a great investment if you're afraid that something lesser would dull and ruin your part by moving it or something.i don't know how much material i removed with it. i cut with it for over an hour and if it's not as sharp as when i began, i can't tell. I ran it with water and a dash of rust lick to clear the chips.

These leave a much worse finish than the usual 1/4" 2 flute straight bits I use

I don’t run these in a CNC. I run them in a Bridgeport & they run fine. I run them at 3,000 rpm & they do what I need them to machine.

Nice set of bits, very sharp. I have been using these for hogging out material from hardwoods on my x carve. I've run 40ish hours on my first bit and still cutting well.

I wish the shoulder was just a hair higher. It's a little too close for comfort when cutting through 1/4" stock.

These are amazing for what I need them for. So far I've ran this endmill through this job 2 times. The program is just over an hour making it around 2½hrs of use in total. This bit is still cutting like butter and ready for the next job. These are the only endmills I will buy from now on. Don't go spend $60 on an Amana when you can get 5 of these sub $40. Just stop searching and buy these. Thank me later.....your welcome!

Works as expected. Perfect for my project.

It doesn’t plunge a straight hole in aluminum, But all other work has been good.

Spetools has been knocking it out of the park. I would fully recommend this to hobbyists and enthusiasts. I wouldn't recommend it to pros because I find you do need to run your machine a little more conservatively to avoid cutter breaks.I am using these on a hobby grade CNC router in aluminum and brass. I would recommend checking out Estcam's Trochoidal milling profiles as it allows you a much deeper depth of cut and that can help prolong tool life.

Awesome little End Mills!I bought the coated 1/16 carbide two flute end mills from here in an emergency to get them quick and I have to say I’m quite impressed. I did not expect them to perform this well, where I broke 4 other of our regular top brand name 1/16 end mills I competed the same job, same feeds and speeds and depth of cut without breaking even one of these. Definitely worth the money, these are great little end mills.

I have used these bits for a while now and they are great. I have a hobby size CNC and I often run these little bits when I need a fine detail and they have yet to fail me. I would and did buy them again.

Bon outil
