Questions about this item

What does the .1340 in carbide boring bar diameter cap in terms of minimum bore size?

The .1340 in diameter sets the smallest hole you can bore; you cannot cut a bore smaller than the bar’s own width.

What shank or holder dimensions does the 290500 boring bar need to mount securely?

The bar is 2-1/2 in long overall; your tool holder must accept that length and clamp the carbide shank without interference.
