A carbide tip brazed onto a ground steel shank makes these tools less brittle than solid carbide tools.

Install these inserts into a matching holder to cut external or internal threads on a workpiece.

These tools come with one high-speed steel insert for use on steel and stainless steel and one high-speed steel insert for use on softer materials, such as aluminum and brass. When one point of an insert dulls, rotate it to use a sharp point.

Install these inserts in an S-code holder to cut precise threads inside your workpiece. They’re designed to sit lower in the holder than other inserts, which keeps them from twisting and lets you thread closer to a shoulder.
