Drill America MMO7/64-2FDE-ST-BN Carbide 2 Flute Double End Stub Ball End Mill, MMO Series

Wow what an endmill! I have about 30mins on this full depth slotting in 3/16" brass. It's nicely balanced (in cut, not speaking of weight), evacuates chips beautifully and has so far stayed sharp. I'll update the review if I have any premature wear.... I have many hours of cutting to find out. for the moment I'm planning to order more.The endmill performance is still good. I had planned to order more but the price almost tripled over my initial purchase; therefore I'll be buying local. Perhaps the initial cost was incorrect?Update: This endmill has proven to be one of the better ones I've used. It give up after 9hrs of slotting 3/16" brass at 11ipm, 18,600rpm or about .0003in per flute which is respectable.

I received this endmill on a Sunday as promised, delivered by USPS. My purpose for it was to mill a .375 wide by .375 deep slot in a piece of 1" cold rolled round bar. This was for a blade guide holder on an antique Delta bandsaw. I am using a 1981 Enco 91002 Mill (made by Rong Fu) for the machining portion of this project. This end mill cut fine, although the hassle of changing three belts to get a suitable cutting speed resulted in my ultimately using an RPM that was too slow. That being said, the endmill cut just fine, doing the job in eight successive passes. Taking too big a bite at low speed resulted in too much chatter, so I had to take my time. Afterwards, the cutter still seemed just as sharp as before. As this endmill was ordered specifically for this operation, I am well satisfied.

Reasonably priced.
