sisona 1/8 3/16 1/4 5/16 3/8 Carbide End Mills Set - Solid Carbide (Tungsten Carbide + Cobalt) - 5Pcs 4 Fulte CNC Mill Bits for Steel - TISIN Coated

Super hard and strong. Drilled through angle iron without any problems. Nice durable set.

put these in my mill and tested them on a few projects and they worked great! def recomend for the price!

So far holding up well.

I will come back and update once I have hada chance to use more of them. Maybe the material I was cutting was too hard. More use will tell.

Awesome! Great Buy.... Very happy

I have been needing to elongate the slot on this bracket so figured would give these a try. I chucked one of them up and went to it. I was not slow or gentle on it ether. I only made two cuts and it loved it. No complaints from it at all and with no lube either. I wanted to see just how well it would do when rushed and did just fine. Kindof surprised for a no namer. I know that will need to run for much longer to determine its true lifespan but for the price I cannot complain. I have a budget and cannot always get the best out there and these fit the bill. Hope this helps and thanks..

If you are looking for cutters that do not break the bank, these are an excellent option. The size range works well for most household tasks and the materials and finish are both great. You cannot go wrong with carbide so long as the coating and your material are compatible so if you are looking for a range of cutters, this is a great option to consider.

Steel is difficult on a hobby CNC, but these end mills are a great set for getting started. With incremental diameters I was able to attempt multiple speeds and feeds for each mill and get a feel for what the machine is able to handle. After some experimentation I was able to get them milling well. In all I have a couple hours on these mills, so it’s hard to tell what the long term durability will be, but in the short term they are sharp, and versatile with no obvious signs of wear yet.

These Sisona bits do cut through thick solid steel pipe and thick ceramic AFTER using a different kind of drill bit to start the hole. You CANNOT use a center punch or anything on ceramic though. And a center punch isnt going to go far in the solid steel pipe I tried to drill through. HERE’S WHAT HAPPENED IN THE STEEL PIPE I got two sets of Stubby Drill Bits for Thick Steel at the same time. The largest NordWolf Bit wasn’t big enough, but it did easily stay centered on a Very Thick, Very Heavy Steel Pipe, and drilled through the first side like hardwood. Then I was going to try the same size bit in this set on the other side and it absolutely would NOT stay, no matter what I did. No matter how strongly I held it or careful I was, it kept walking and wandering off to the side. I tried a lot of times, and it would Not even START to drill a hole. I really wish I could have actually got a hole drilled with one of these bits, because the NordWolf only stayed sharp for the one side. It went completely dull on the very next side. Didn’t even drill two holes. HERES WHAT HAPPENED IN THE BOTTOM OF THE LARGE CERAMIC POTS Two large Ceramic Pots outside needed holes in the bottom before it rained. Again, the NordWolf drill bit was too dull after one use to even start the hole, so I used the next size down. And again, these bits absolutely wandered and walked away constantly, even from the starter holes I made!! I finally finished, but my cordless drill worked harder than ever before. I hope its OK.

This is for the Sisona carbide end milling bits. These really do a great job cutting thru steel, both mild and stainless. Does a great job on aluminum too. These 4 flute end mills will need their own collets, each bit has a different diameter, so youll need 5 collets. But if youre buying carbide end mills, chances are you already have the collets. I like that each end mill has their own labeled plastic box. Makes it easier to find on the drawer holding my end mills. These held their sharpness over the few cuts I made so far. Ill update this if anything changes.
