Default Square Diode mount

I am going to be doing some work with tec's and laser diodes.
Currently I am using one of these:
http://www.amazon.com/AixiZ-Aluminum...7982459&sr=8-1

But the hole is way to big for an aixiz module, it is a verry lose fit.

What can i use that would be better?
Is this one any better?

anyone know of a direct press square heatsink?

Aluminum or copper offers very little performance increase over brass. Junctions between materials have higher thermal resistance and if you're being anal-retentive about thermal transfer, those are what you want to eliminate. Going from die casing to copper aixiz to copper block will probably have a higher thermal resistance compared to this brass block simply because of the extra junction. The thermal resistance of the brass itself is close to zero.
