Use these tools to enlarge existing holes to precise diameters.

Insert the square shank of these tools into the slot of a boring tool holder and use them to enlarge existing holes to precise diameters.

The diamond tip on these tools offers superior cutting performance on nonferrous and nonmetallic materials, such as aluminum, copper, fiberglass, and plastic.

These sets contain some of the smallest boring tools we offer.

Constructed of a carbide tip brazed onto a ground steel shank, these tools are more wear resistant than high-speed steel tools.

Reduce tooling setup time—install the holder once and alternate between applications by switching out the bit.

Pair one of these inserts with a compatible boring carbide insert holder with coolant hole.

Use these tools to enlarge existing holes to precise diameters. They come with an insert installed. When one edge of the insert dulls, rotate it to use a sharp edge.

Secure carbide inserts inside these holders for stable turning.

Pair these holders with a threading insert or a grooving insert to make cuts on the outside of a workpiece.

Pair these holders with a tool block for right- and left-hand mounting in a lathe.

Fit these holders directly into a lathe tool post or appropriately sized holder without the need for a tool block.
