I just bought a Stanley 923-10 brace on e-bay. Today, so I haven't recieved it yet. It now occurs to me that I need some bits (augers?) to go with the brace. I have never used a brace so I don't know what type of bits to get. On e-bay I see a lot of "IRWIN" auger bits. They mostly have truncated pyramid square ends. Is this the style of bits/augers I need? If not, then what do I need? Also, any thoughts or comments on IRWIN or other brands? Any help is appreciated.
