AUTOTOOLHOME1/8" X 1/4" HSS 4 Flutes Straight End Mill Cutter Pack of 2 CNC Milling Drill Bits Router Bits for Wood Aluminum Steel

Bought these for milling small details in brass bar stock. They worked okay at first, cutting without too much effort. The quality of cut quickly went down though. Both end mills broke after a very small amount of work. I got the cuts done I needed to, but I was overall disappointed in the quality. I guess you get what you pay for.

Not for hard metal!!! Had a 3/8 long by 3/16 slot for a sight install on a cut barrel for a handgun. Went through 3 out of 4 of these and not even half way done..... Total waste of money and time.

Burned up immediately on machining steel when other endmills have no problems on the same settings. I’ll only be able to use these on wood.

I have several end mills but have found this 4 flute end mill to be great. The 1/4 inch shank makes it stronger and has a very smooth cut.

I purchased these to mill some Damascus. After the first use, they have become misshaped. Might have been my fault for not buying a higher quality. Would probably be great for non ferrous metals but definitely not anything that has a bit of hardness to it.

Functions as advertised

These work well at a great price and don't break like some others.

Exactly as described. Really good deal.
