I'm so used to carbide tooling that I didn't realize this cutter wasn't a carbide cutter until I looked up my past orders. I've used this in steel, aluminum, and some plastics. Seems to cut everything like butter and I've had no problems with anything getting gummed up in the flutes. It leaves a fairly smooth surface. The groves from one flute don't align to the same groove in the next flute, so you wind up with a smoother surface than you might expect. Will definitely buy more - these cost less than half of a good quality carbide cutter in the same size. Notice I said good quality. I've had some carbide endmills, bought here on Amazon, that were pretty awful.

For starters, I am not a machinist and don't have a milling machine or any real mill experience. I needed to elongate some 3/8" bolt holes for in 1/4" thick steel hinge brackets for a wrought iron gate. Tried filing and using a Dremel grinding stone to no avail, or at least too slow progress for my patience. So I chucked this thing up in my drill press and along with a cross-slide vice created my poor mans milling machine. This tool went through that steel in no time and made clean slotted holes. I used regular drilling / tapping fluid and it was a little noisy, but I was careful to not cut too fast. In maybe 5 minutes per hole and they were now clean 3/8" x 3/4" slots and perfect for getting the gates aligned again. When finished the tool still looked and felt brand new.

real tuff bit.

Sharp. Leaves a better bottom finish than expected. On my small mill it will take a 0.100” deep full width cut without a problem. Side milling 1/2” deep at 0.040 is no problem either.

Works well and great price

We just got our bit in today and don't get me wrong I consider my self kind of green. But with my Grizzly Mill and lathe combo that I have in my shop and going through to date only a few sets of bits, I am say I am loving this, very aggressive cutter that for me at this time, very impressed.

this was cheaper than my vendor and quicker. had little faith it would last or work.. but was throughly impressed with its preformace it took the job I was on and was able to slot in great time with great results and it worked on a few different set up.

This end mill is worth its weight in gold. Takes a lot of material in each pass yet leaves an acceptable surface for most things. End milling is just plain nice and side milling leaves parallel grooves which may not be a problem but can always be cleaned up with a finish pass using another end mill. Plenty tough too.
