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

Well made high quality end mills. They seems to be made of solid carbide. Im happy with them.

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.

I use these with my Grizzly mini-mill - they are just the right size for a light duty machine. Useful range of sizes, and economical. Recommended

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

The machining of theses end mills is good. It is not on par with high end U.S. made mills but it is still very good. For the price this is a good deal. These are center cutting mills. I will be using them in my Bridgeport and Kondia Bridgeport clone. Remember, no one ever said I have too many end mills.

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.

They look very good

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.

We’ll packaged and good quality

Tested the 5/8” cutter in hot rolled steel, was able to do a full width cut at 2mm depth with a feed rate of 480mm/m on my CNC converted HF mini mill. Surface finish was excellent given the rigidity (or relative absence!) and I was very pleased with the speeds I was able to achieve - quite aggressive for me but felt I should put the cutter through much more than I ordinarily would for the purposes of this review. These cutters are definitely on my must buy list. Ran it dry and did four faces on two 1/2” x 3/4” x 4” pieces. Photos show finish from roughing operation and the blue chips it produced with no sign of cutter deterioration after removing a total of 1/4” over a length of 16”!
