Is it possible the effect of crush size is positively correlated with OG Assuming the differences observed between the Imperial Stouts from the first xBmt were a function of crush size and not some extraneous variable it seems at least plausible the higher amount of grain and resultant OG may have played a role.

### Understanding Chip Formation in High Performance End Mills

Destiny end mills also form a manageable "6" and "9" shaped chip by traveling down through the gullet to the core diameter of the end mill. However we have developed a rake face geometry that enables the material to curl in the outer rake face as you can see by the red arrow above. By doing this we create much less friction (and HEAT) in the tool which translates to longer tool life.

### Ball Nose Milling Strategy GuideIn The Loupe
