SPEED TIGER IPVE Carbide Square End Mill for Stainless Steel - Unequal Flute Spacing & Helix Design - Anti-Vibration - 4 Flute - IPVE1/44 - Made in Taiwan (1 Piece, 1/4)

I have used these on aluminum and stainless steel. Aluminum is butter, SS needs a slower feed rate.

I use this as a router bit and its incredible. Ive routed fir, oak, mahogany, aluminum, brass, and thin mild steel. After 3 months of occasional use (only about 5 minutest a day averaged out) its still about as sharp as new. I use it primarily to open up strike plates for customers whose doors arent closing properly and its been a godsend. Try it out; what have you got to lose?

Perfect as described

This endmill cut .06 deep flats on 304 stainless 800 times. Then cut some plastic because I was too lazy to change it out. Cut like butter. Nice product!

Ive used other bits, I could have been using a pensil eraser. I used these bits on my little milling system. They went through stainless steel BEAUTIFUL!!!!!

Great endmills. One 5/16 has milled the outside all of these in 304 stainless and still running.

Its a carbide bit. Nothing magic, but good quality and a price that makes it easy to stock up on frequently used sizes.

I used a lot of cutting oil, but this done the job I needed it to do. Very, very happy with this end mill. Fits perfectly in my drill press.

I ran 100pcs at 5000rpm, 80 ipm and dry no coolant with .055 radial cut at 1 deep, 2 endmills did the whole job! Dont believe take a look at high speed machining on SS on the tube!

I ordered a set of high-speed steel bits and found them to be woefully inadequate. I ordered and received these bits to find that they are sharp and cut much cleaner than the HSS. I strongly recommend buying these as individual components versus the set I bought direct from the mill manufacturer.
