28mm Dia 60-Degree Silver HSS Double-Edged Dovetail Tool Metalworking End Mill 12 Flutes

I broke a few teeth off trying different climb cuts that didn't work out. It seems to still cut pretty well with a slower feed rate now that I'm down to about 6 or 7 teeth all bunched up on one side.

I don't use this type of bit often so can't say how durable it is. But it looks like decent quality and should fit my needs. I have a Sieg mini mill so mostly mill soft metal, and this should last a pretty long time.

A sharp cutter with little runout that arrived on time. The price/quality is right for the home shop but maybe not for a high volume commercial shop

The cutter head has a wobble, and yes I did check the collet. I took my time and slowly fed the cutter through the material using plenty of lubricant. I was cutting softened 4140 steel and the cutter did the job so, for $20 dollars I am happy.

I needed this to manufacture an adapter for a gunsmithing job. It showed up pretty quickly. When I opened the plastic storage tube, the first thing I noticed was the rough, almost primitive grinding of the cutting edges. Then there were slivers of steel from grinding still attached to the edges. There was no time to return it, so on to the shop. Chucked it up in the collet, and started to the cut. Dang cutter had a lope, about .005-.007 non-concentric. I managed to finish the job, holding my breath hoping the cutter didn't frag on me.

had o make a 60 degree slot for a slider part

Haven’t tried it yet, looks good

I don't believe this is really high-speed steel, as stated. It chipped and burned on light cuts in mild steel. I could not come up with a set of feeds and speeds that worked. Returned it.
