McMaster gets some clinkers.

I ordered some 4140 bar stock, supposedly annealed. Machined rather
poorly. Made the part, delivered to the happy customer. It was a one
off gib that had been lost on a BP size mil (KO)l. I was in a hurry.

Well it finally bugged me to the point of measuring the hardness.
IIRC it was ~20Rc, not quite pre-hard, but much harder than annealed.
McMaster can't measure every incoming part, so I don't blame them, but
**** happens.

So tell McMaster and have them ask their supplier to replace your
cutter--at the supplier's cost.
