Deliver coolant through the holder to keep workpieces cool while boring tough materials, such as steel, stainless steel, and nickel-based alloys.

These sets have a variety of indexable boring insert holders with carbide inserts and a wood storage stand. When one edge of a tool's insert dulls, rotate it to use a sharp edge to enlarge existing holes to precise diameters.

To limit downtime when you’re changing out cutting tools, these boring bars adapt standard lathes for use with quick-change cartridges.
