2PCS 1/2'' Carbide Square End Mill Bits Set, Milling Bits Cutter 1/2 Carbide End Mills for Alloy Steels/Hardened Steels, HRC 45 Deg Single End 4 Flute AlTiN Coating (2PCS 1/2in)

Wonderful bits! Drilled 12, 1/2 inch holes through1/4 inch plate steel and only needed one bit. I know these are milling bits, but it would be nice if they would have had a very small center tip for lining up with your center punch hole. We used them in a mag drill not a milling machine. After the 12 holes were drilled the bit showed very little if any wear. Don't forget to use the cutting oil folks!

Normally I prefer to buy lathe and mill tooling that is made in America, S Korea or Israel but these were purchased at a very attractive price. They're very sharp and have been used on steel, aluminum and brass with great results in my heavy and rigid American made mill.

They are good quality tools. haven't used them much yet, but what I did use them on they preformed well.

It did the job I needed it for. No complaints.

Cuts tool steel easy. Holds edge.

does the job

Great Value. Good Bits. No complaints. Will buy again if price remains a value buy.

Both broke within the first 30 seconds of use

Good value for money
