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

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.

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.

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.

I finally got a chance to try out these endmills recently, and so far theyve been working great. Ive mostly used the 3/8, and its been perfect for my uses. I used it with some 1018 steel, 6061 aluminum, and O2 tool steel with my manual mill and it doesnt have any signs of wear yet. I hogged out some material on the piece of 1018, taking quite heavy cuts just to test the performance, and it worked well and cut like butter. I measured the grind of the flutes, and its only a few tenths small. I was able to hold a thou tolerance very easily. For the price of this set and the use Ive gotten from it so far even with only one of the endmills, Id say its 100% worth it. Ill update this review later on if I get a better scope of the durability or if any issues happen.

These are perfect for home use, hobbyist. My husband is in the manufacturing engineer world and deals with machine tools day in and day out. While they are not the caliber for high-end CNC machining, he was impressed with them for home use. If he has an update I will be sure to post it.
