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 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.

Cuts well and stays sharp

Perfect as described

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.

Used this in my hand held air grinder. Works amazing, sharp, cuts great, proceed right, easy yes to buy this EM

Im new to milling and this bit is the best one I have used so far. Ive order one from a different company that was the best money can buy and unfortunately it didnt hold up to the speed tiger

worked like a champ

product worked as expected.

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.
