Boring heads for the mill

[PixMan]

I had bought my dad a 3" Enco a number of years ago. Back then they were made by Gamet in France, and are fairly good quality. The tool accepts 3/4" round shanks, so I've made bushings to be able to use smaller boring bars. We have a set of the cheap China made brazed carbide bars, all 3/4" shanks. The carbide sucks so you have to be careful using it. I have a few solid carbide bars from Micro100, from 1/2" down to 3mm shanks. I've not yet made a busing for the smallest ones though.

I cannot recall ever wishing for a smaller boring head than this 3" one, and only once for a larger one. I've bored down to about 3/8", and up to just under 12" with this.
