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 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.

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 will buy more from this company. Compared to what I have been using this tool is amazing.

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!!!!!

Good endmill for price, will buy again

Ive tried at least a dozen carbide tipped cutters (reciprocating blades etc.) that claimed to cut cast iron, all of them dulled or broke (lost teeth) after 6 or 7 cuts (up to 3/16 thick). Yes, at slow speeds with cutting oil. This is the only one that still cuts after dozens of uses.

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

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