High-Performance Carbide Tungsten Flutes Milling Straight: Precision Cutting Tool for Superior Results Review

Cheap end mills, real carbide. They're perfect for novice machinists who can cuss and cuss for forgetting to set the X-axis motor to a proper speed before turning it on. But then you can smile because it's not the $80 you just broke. Really decent for the price.

I am very happy with these bits although I didn't like that the length of the cutters went up too long (towards the tip of the drill). nice if they had a small cutting length of 1/8 inch. However, my end mill was flawless (even the first time!) I still laugh at how easy it was.

So far I've drilled a 1" pocket 1" deep in mild steel with a 10mm end mill with no problem. Run at 2500 RPM at 5.5 inches per minute with a depth of .1875 inches per pass and a 20 degree incline at 5.5 inches per minute. As a CNC hobbyist, I make my fair share of gcode errors, it's a lot nicer to rip down a $35 set than a $100 bit. I will continue to buy them here as long as the price stays the same.

I've seen the term "tungsten carbide steel" before and the products turned out to be mostly high speed steel with (maybe) some tungsten in the alloy so I was skeptical when I saw the title of this one list . Haven't used these end mills yet so can't comment on how well they work, but their extremely high density (very heavy for their size) leaves no doubt that it is indeed tungsten carbide!

These end mills are not suitable for woodworking as the nitrile coating causes some sticking of the wood material. However, they worked great and offered great resistance to my clumsy indulgence. I managed to break 3mm after trying to zero a piece of solid wood without turning the spindle. In fact, he lasted longer than I thought he should have. In general very satisfied.

I was expecting HSS to have some sort of carbide-like coating, but it's actually solid TC. I don't do any serious work with them, I just work with a cross vise on a large mild steel and carbon steel drill press, but overall these things still make good chips. I have no idea how they will perform in a real grinder, but if this drill press setup indicates they should cut like butter.

I bought these bits for personal use after hours and for side projects at the machine shop I work at (I won't pay to replace the end mills they have). I can say they work just as well as the more expensive ones. Using a 12mm end mill, I made a 1.5" slot through a 2.125" D2 shank with a depth of cut of .187-.25" and did it much faster than I would have on a Bridgeport should do. If they can ram through tool steel, they can easily penetrate any of the softer materials!
