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)

Ive gone through my share of endmills and they always burn up as with a 24k rpm spindle, going less than 3000RPM is not easy as the torque available is almost nil. I bought one of these for hardened steel and stainless steel I needed to mill and this endmill Ive got actual cutting time so far 6 hours contact in hardened steel and 11 hours in stainless steel total and this still cuts like a hot knife through room temperature butter. 3137 rpm at around 650mm/min works great in either metal. 1st order from this company and wont be my last, in fact all my purchases will be from this company.

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

Cuts well and stays sharp

Good endmill for price, will buy again

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!

product worked as expected.

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

Perfect as described

Great end mill for the money. Only used on aluminum, dont know how it will work on steel.
