Just like the add said and was perfect

great product great durability

I use this end mill to make hard wood and bone knife handles. Seems to work very well.I would recommend this end mill, it may be worth a try for u ya our application.

There bits were ordered to solve a routing cut problem I had. First, some background - I have 2 CNC Routers. One is home built from a kit and the other is from a US based manufacturer. I use Vectric's CUT2D software to generate G-Code. One of my projects had relatively small letters using a "stencil" font so there were no un-supported letter parts. I tried using a V-Bit but as it went deeper, the letter sides would become too thin and fall apart. The smallest end mill I had before buying these was 1/8" inch. My letters were so small on a 2" x 4" field that a 1/8" mill could not cut all the slender parts and I was left with gaps in the letters.I ordered these 1/16" bits in an attempt to pocket cut the letters and retain the delicate lines. They worked spectacularly! I first used my smaller CNC to test cut a block of pine wood. The bits made clean, sharp cuts with almost no after routing work needed in the corners or the top edges. For the main cut, I used my larger machine and cut the letters in 1/8" thick polystyrene plastic. The end result was perfect. Clean cuts all the way through and no melted edges. The 2 flute design allows chips to fly away via the vacuum device is use to keep the material clean. The bits cut cleanly and without any heating to melt the plastic base.So far, I have cut polystyrene, MDF, and pine wood with no clogging or poor edges. I will look to this supplier for additional bits in the future.

These aren’t going to build your titanium SR-71 but in my Makita router at 20000 RPM and 15 IPM cuts 6061 Aluminum very well. I use air blast to clear the chips and the bit lasts longer than I would expect.

I needed to cut some cold-rolled steel on my desktop CNC. Typically steel is not a material you want to cut on a desktop CNC which tend not to be as rigid as necessary. But with some well-thought out feeds and speeds it is possible. I bought the 2 Flute - ISE1/8"2T set of end mills. And I'm very impressed. I ran the machine at 15k rpm, .5mm DOC, and 150mm feed rate. The end mill was outstanding. It didn't chatter, it cut smooth as butter and the finishing pass left a very nice finish on the edge of the cuts. You know what else, the packaging the end mills came in was very nice too. I know that isn't important but most manufactures don't even think about packaging. To give some perspective I use mostly Spektra end mills from Amana Tools, and Whiteside end mills, both for wood. These Speed Tiger end mills were my first introduction to cutting steel.

I had some work to do on some AL (7075-T6) with a Harbor Freight Mini Mill and it worked fine. It had some chatter but some is to be expected with 2-flute cutters anyway. I had to hog out a pocket that was 1.25" deep and down toward the bottom of the pocket the chatter got a little worse but nothing horrible. Again, this is to be expected with this style of cutter. I kept the vacuum going to keep the cutter from cutting through its own chips as much as possible and that helped. The finish was good enough for my needs but I have a 4-flute end mill so I took off another .001" just to smooth the finish even further but again, it wasn't really needed.

Not bad for a cheap throw away carbide bit. We typically use the cheap bits when experimenting on something new before we tear into in with the expensive bits.
