There Is No Substitute for Sharp Tools

That includes drill bits, saw blades, end mills, and today's subject, boring bars. I am boring an aluminum cylinder and cutting was going poorly. I looked carefully at the carbide tip and the problem was obvious. Fortunately, this is a rotatable carbide tip. To do that you need a teeny tiny Tor-X (T7) which is Alford slightly larger than this letter o on a 13" screen. (Do you remember 13" computer monitors?)

It bores so much better now.
