Boring Carbide Insert Holders
Shown with Insert Installed
These holders conform to ANSI standards. Pair them with an ANSI standard carbide insert (sold separately) to enlarge existing holes to precise diameters. When one edge of the insert dulls, just rotate it to use another edge. Right-hand holders are for boring when the workpiece is rotating counterclockwise (toward the lathe operator). Left-hand holders are for boring when the workpiece is rotating clockwise (away from the lathe operator).
