SPEED TIGER ISE Carbide Square End Mill - Micro Grain Carbide End Mill for Alloy Steels/Hardened Steels - AlTiBN Coating - 4 Flute - ISE7/64"4T (5 Pieces, 7/64")

They appear to be well made-super sharp. Their performance is tops.

Used it to cut a 1/2" keyway into a shaft 7" long. worked with great satisfaction

These are some of the best carbide cutters I have ever used

Bought these for a hobby. Received them and like that they are packaged individually, thus helping keep them sharp. Used them on a firearm building project and only eneded up using one. But stayed sharp and met the needs of what I was using it for. If your are a hobbyist and looking for some high quality milling bits with out having to pay a premium these are the ones to go to.

I use speed tiger endmills on my Bridgeport every day. They are verysharp and stay sharp for a long time. cut gummy 1018 steel like butter dry. sharp enough to cut aluminum. Work great on stainless and tool steel. Surface finish on facing is always close to mirror. edge is fine for machine parts but would need to polish for ornate parts. If you are breaking these things. Lock the x when cutting x and lock the x when cutting y. Don't make heavy climb cuts without drag on the current axis lock.
