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

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.

I would call these a good value for money. They showed great durability in a 1952 Bridgeport mill cutting 304 stainless steel.... and I cut a lot of it on a single cutter. Good job, I will buy more.

These are not the top of the line, but you do get what you pay for, they will do the job, but the longevity of the bits is not that of the higher quality bits

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

Works great

So far holding up well.

These end mills are a good value. They cut through steel without issue and left a good clean finished surface that needed little finishing to smooth out.

Used these end mills on a project I am working on, and they cut the aluminum and steel just like my other brand end mills do. so far, I love them and would not hesitate to buy more when different end mills are needed for future projects.

Excellent cutting endmills. I ran these dry at slightly higher speeds and feeds than my usual carbide tooling and they performed just fine with no signs of dulling or overheating. Cutting was almost silent and very fast. I examined the cutting edges after cutting in steel for a while and they showed no signs of premature wear. There were no signs of chip welding at all. Cuts were very smooth and practically burr free. A very good set of cutting tools. Real happy with these.

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..
