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

We’ll packaged and good quality

These have been working well for a home gamer like me. I dont use them a lot, but have not had any problems and they do a great job.

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.

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.

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 carbide end mill bits are incredibly well made. They are very sharp and cut cleanly. This really is a fantastic value. I highly recommend them.

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..

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.

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”!

Awesome! Great Buy.... Very happy
