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.

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

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.

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.

Works good

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.

Worked great

Works as described

Great endmill. Use on 316ss. I never do reviews but had to say something about these guys

Good endmill for price, will buy again
