End mills are machines that are used to cut and shape different materials like steel, plastic and wood. The end mills are similar to drill bits in most ways except that they do not cut downwards but sideways. As there are a variety of end mills available, choosing the best one should not be too difficult if you are aware of your requirements.
The end mills differ from each other on the basis of size, material and numbers of flutes or cutting edges. The end mills can be chosen as per their coating, angle and shape of the tip of the cutting edge. When choosing the type of end mill to be used, you must be aware of your requirements as different end mills are used for different applications. The carbide end mill sets are expensive and harder than most other end mills. However, the higher cost of the end mill is offset by the increased output.
We researched the market and have compiled a list of the best carbide end mill sets available from several brands. These mill sets have been reviewed on the basis of the features mentioned above and their price. You can find the appropriate mill set for your requirement after perusing through our list.

I have used these end mills for making slots in 18-8 stainless steel. they are excellent and have surpassed expectations. I bought another brand for roughing but they failed before I made my first pass but these did the roughing and finishing with no problems.

I got this set for my Sherline mill to do gunsmithing, woodworking, and small work. They are sharp and come in a nice spruce holder to protect the bits while in storage. The cutters seat just fine in the holder and they do mill great even at low speed. So far I have used them in 4140 steel for cutting dovetails as well as on maple wood for precision stock carving. They work just fine. There are some others who think its only good for aluminum. Aluminum is pretty easily machined but I give it credit for steel work and for most of your general milling needs. Oh yea, do not forget lubrication.

This is exactly the set sold at Harbor Freight. Identical packaging and everything. 5 stars is not to in anyway speak to the quality or usability of these end mills. 5 stars reflects that it is the same set that Harbor Freight retails for $79, and I got it for $30 less.Read other reviews for comments on their quality and application, I just got them to screw around with while I learn how to use my mill assuming I will break them all. I have no previous experience with machining and cannot compare them to anything else.That said, if Harbor Freight crap is good enough for you, then this is even better.

So I built a very cheap and loose CNC machine using a RotoZip as a router. I was originally very disappointed with its performance. After swapping the spiral cutting bit made for the RotoZip with one of these HQMaster router bits, I feel much, much better. The old RZ cutting bit could not run properly even at 100 mm/min with a layer depth of just half a millimeter. My CNC uses small NEMA 17 86 oz/in motors with 5/16 18 tpi threaded rod for the axes (yes, cheap build). It was hard for the motors to push the bit even at this slow speed and very low cutting depth and it skipped lots of steps. When I tried this HQMaster bit I got it to go at 300 mm/min with a layer depth of 2 mm and it was like going through butter (in 19 mm pine board), without the X/Y motors skipping. It can probably do even better (faster and larger layer depth) but that’s as far as I’ve pushed it this evening. Still, it’s way, way ahead of the normal RotoZip cutting bit. Additionally, when it cuts, it barely makes any more sound than the router normally makes spinning freely, the old RZ bit was very loud when it was (barely) cutting. I even had an accidental command move this HQ bit cutting at a depth of about 10 mm through the pine, and though the motors were skipping at 300 mm/min, it still went through the wood a few centimeters before I could eStop the machine. Getting 10 bits at this price is amazing because the normal (and much less capable) RotoZip bits are around $8 at Home Depot. The only advantage with the standard RZ bits is that they are much longer, I can get about 20 mm of total cutting depth with these HQ bits, which is enough for my purposes. Now, my cheapo CNC can actually be used to make better parts for itself. I’m very glad I made this purchase, these bits make all the difference in the world for my CNC.
