Wokesi Pack of 7Pcs,1/8'' 5/32'' 3/16'' 1/4'' 5/16'' 3/8'' 1/2''Blade Diameter,High Speed Steel (M2AI),Full Grinded,Square Nose End Mill Cutter CNC Router Bits (1/8+5/32+3/16+1/4+5/16+3/8+1/2 4Flute)

The four stars do not reflect the quality of the bits, only that I have only used the 1/4" bit in a trim router to clean up some dados made with a cheap straight bit. The bit worked well in soft wood and cut clean. I purchased 3/8 and 5/16 collet inserts to be able to use two end mills that are not 1/4 or 1/2 shanks. I do not own a CNC or milling machine, and plan to use them with hand held routers in home made jigs. So far they are doing what I need, cutting cleaner and cooler than common straight cut router bits.

I just got these a couple weeks ago and have used them once or twice. Even so, they have performed outstandingly. One job required that I cut out the middle 5/8" of a piece of 3/8" thick channel. The mill cut through the full dimension like butter. This was a dry cut at 425 rpm and I expected that the tool might overheat but it took it just fine. The other job was elongating a 5/8" slot. Again, the steel peeled off and the tool stayed nice and cool. I can see that these cutters are going to do a lot of good work and be one of my first choices when setting up the mill.

Every one of the 7 bits I received had at least one chipped flute. Some arrived with multiple chipped flutes. They are not usable. The fact they left the factory with these obvious chips present means there is absolutely no quality control or checking of these bits before they leave the factory. They are garbage.

I usually buy name brand mill cutters, but I used these in a pinch and was pleasantly surprised how well these did. I was using them to cut slots in steel and they held up better than I anticipated. I would buy again. I'm a hobby machinist, so they will probably last me a long time.

Trash, no surprise. Blades chipped instantly, and they chatter like crazy in my press. I used them to slot aluminum and 1/8 hot roll. I guess they got the job done but it took forever! And scared the crap outta me.

Yes, cut slots in milld steel.Worked very well.I used them on a Mill with cutting oil.When they start to dull, I will purchase them again.

I HAVE USED THESE END MILLS TO COMPLETE AN 80% AR15 LOWER RECEIVER. THEY WORKED FINE. I WILL BE WORKING ON ADDITIONAL 80% RECEIVERS, BUT I DON'T EXPECT THESE ENDMILLS TO STAY SHARP WITH CONTINUED USE. THIS ITEM WILL BE ESPECIALLY GOOD FOR POLYMER RECEIVERS AS OPPOSED TO ALLUMINUM RECEIVERS. I LIKE THE FACT IT IS A SEVEN PIECE SET, MAKING IT USUABLE WITH DIFFERENT JIGS.

Been using these for a while now and even though I'm just a beginner they are holding up fairly well,have been cutting mild steel and they seem to hold an edge pretty good, they are also very accurate, I measured them and each one is consistently half a thousanth of an inch under their stated size. Will definitely buy some more as I've already broke 2 due to my inexperience.

Brocas diferentes a lo entregado, en la imagen aparecen 7 piezas, sin embargo solo recibí 6 y diferentes a lo mostrado, son de buena calidad pero es una pena tener que quedarme este producto sin una broca, pues me urgía para terminar un proyecto.

fait du bon travail

I used the 1/8 bit and the first time using it snapped it of and I was using it on aluminum with very little force.

very good tool
