[Shop-talk] drilling a square hole

[john niolon]

you guys might have seen this but it got me giddy just watching it.....



TOOL HEADS !!! (it's like a gear head but with tools) PAY ATTENTION. how many
times have you needed a square hole and had to drill it out and then work with
a file to square it up..... the Japanese (those crafty bastards) have solved
your problem...this is just too dang cool (and expensive probably)
