Homemade Boring Bar - Low Cost, Fun Project. Turn, Thread, Groove, Radius etc.

[Janderso]

Here are a few of my self made boring bars. The 2 on the upper left take square inserts. I made these in the 80’s. All others were made last year. Everede style, insertable internal thread and insert triangle. 3/4”,5/8”&1/2” diameters

I also have some at work that take round blanks. The easiest type to make. 5 minutes and you have a boring bar.

Cutting oil is my blood.

Very nice!
Well done
