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

My wife ordered this for me through Amazon vine, so this is her husband leaving the review. Good quality carbide for the price. From my typical suppliers, these would have cost a lot more.

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..

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.

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

Ive used thede mostly for drilling into hardened steel receivers and barrels. It works great for cutting out oin slots on round objects. When my other more expensive drill bits have failed this set has gone through the same material like it was butter. They are a little short cut so for deep holes you will need to do alot of back and forth to prevent jams and damage. Over all im happy with them.

I get it these are specialized tools. Not everyone has a milling machine. Well, I know someone that does and I have some parts that will need milling. Since I know I want him to do it as a friend, I figured this would be a nice trade. These are Tungsten Carbide and cobalt. We will be cutting a steel hitch that is 2.5” and needs to be milled to 2.0”. While we have not used them yet I am told that this is a good set and exactly what is needed to do the job. As far as price goes, I am no expert on these. I see prices for way less to way more. Once I see them cut the value will be in did they work as expected. When I have time to go over and he has time to mill, I will update my review. For now, not having much to go on except my friend the expert’s word I think this is a good set and recommend them.

I must say these are a lot better than I anticipated. And I cut through some pretty hard material and they’re still sharp.

I wont know how durable these are until Ive worn one out. But I make some test cuts with them in a small mini mill (the common seig X2 that is sold by Micro Mark, Grizzly, and many others) on mild steel plate. They had no trouble making smooth clean slot cuts .030 deep x 5/16 wide in a single pass. They definitely cut with the sharpness and smoothness of carbide. Then I tried some facing, edge, and plunge cuts in the same mild steel, and got good clean results. It throws neat, uniform chips with no burning or chattering. How long will they last? Who can say. But they do a nice job as new.

Works great

They look very good
