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

So far holding up well.

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

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.

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

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 bits are very sharp and durable.There is no visible wear and tear after long time of work.I am happy with it.

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.

Perfect bits.

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”!
