Use these tools to enlarge existing holes to precise diameters. All have an offset taper that provides additional clearance to prevent chips from clogging the hole.

C2 carbide tips are abrasion resistant and less likely to chip or crack than C6 carbide when cutting aluminum, brass, and bronze. C6 carbide tips hold up better than C2 carbide when making cuts in steel.

The long steel shank on these tools can reach farther inside the workpiece than standard boring tools and can be cut to length depending on the depth of the hole. Use them to enlarge existing holes to precise diameters.

Tips are micrograin carbide, which outperform C2 and C6 carbide tips when cutting difficult-to-machine metal, such as stainless steel or titanium. They provide a good finish on most materials.

Right-hand tools are for boring when the workpiece is rotating counterclockwise (toward the lathe operator). Left-hand tools are for boring when the workpiece is rotating clockwise (away from the lathe operator).

This set contains some of the smallest boring tools we offer. Use them to enlarge existing holes to precise diameters. Made entirely of micrograin carbide, which outperforms C2 and C6 carbide when cutting difficult-to-machine metal, such as stainless steel or titanium. It provides a good finish on most materials. Tools have flats on the shank for quick alignment.

These tools come with carbide inserts installed. When one edge of the insert dulls, rotate it to use a sharp edge. When all edges dull, replace the insert rather than the whole tool. Right-handed tools cut from right to left, left-handed tools cut from left to right, and neutral tools can cut in either direction.

Style AR and AL tools perform along-the-length turning, facing, boring, and chamfering. They allow for a sharp 90° square shoulder.

Style BR and BL tools perform along-the-length turning, facing, boring, and chamfering. They are suitable for roughing cuts, interrupted cuts, and cuts where a square shoulder is not required.

Style E tools are for external threading.
