Abstract
Abstract A boring head assembly comprising a head having a radially extending slot, and a removable blade-carrying slide adjustably mounted in the slot. A reference block is also adjustably mounted in the slot having a locating surface adapted to contact and radially locate the slide. A microscrew carried by the block provides a second slide-locating surface.
