Install these inserts into a matching holder to cut external or internal threads on a workpiece. They are compatible with top-notch style threading, which uses a highly-rigid clamping design, resulting in a smoother finish and superior tool life. When the first point dulls, flip the insert to use the second point.

60° V-thread inserts cut a range of UN thread types and sizes.

NPT thread inserts efficiently machine full-profile NPT threads.

Pair a right-hand insert with a right-hand external holder or a left-hand internal holder. Pair a left-hand insert with a left-hand external holder or a right-hand internal holder.

Pair these holders with a threading insert or a grooving insert to make cuts on the outside of a workpiece. A highly-rigid clamping design results in a smoother finish and superior tool life. They are compatible with top-notch style threading and grooving systems.

Use a right-hand external holder with a right-hand insert when the workpiece is rotating counterclockwise (toward the lathe operator).

Use a left-hand external holder with a left-hand insert when the workpiece is rotating clockwise (away from the lathe operator).

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. When all points dull, replace the insert rather than the whole tool.

Tool with 3/8" shank can cut external right-hand threads.

Tool with 1/2" shank can cut external right-hand threads with one end and internal right-hand threads with the other.

Tool with 3/4" shank can cut external right- or left-hand threads. To cut right-hand threads install an insert in the pocket on the left side of the tool. To cut left-hand threads install an insert in the pocket on the right side of the tool.

A carbide insert comes installed on these tools. When one point of the insert dulls, rotate it to use a sharp point. When all points dull, replace the insert rather than the whole tool. A neutral cut direction means these tools can cut from either right to left or left to right.

The carbide tip brazed onto the ground steel shanks of these tools is more wear resistant than high-speed steel. Right-handed tools cut from right to left, left-handed tools cut from left to right, and neutral tools can cut in either direction.

Right-hand and left-hand threading tools are for working close to the chuck.

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.

Micrograin carbide tips 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.

When cutting threads in nonferrous and nonmetallic materials, such as aluminum, copper, fiberglass, and plastic, diamond tips provide superior cutting performance. A neutral cut direction means these tools can cut from both right to left and left to right.
