Steel is Harder Than the Brinnel Hardness Numbers Suggest
I was battling with squaring an aluminum tube this morning, and I suddenly remember that when cutting gets difficult, it usually means the cutting tool is dull. I think the squaring of steel a few days ago is the problem. I just ordered new carbide tools, but I also notice the carbide tips are indexable, if I can find the right Torx tool. Whoops! Some of their cutting tools are indexable; not the relatively cheap ones I use.
