Description
Product Overview
The 1/2″ Internal/External Threading Tool from Arthur R. Warner is engineered for precision machining in both internal and external applications. Constructed from high‑speed steel (HSS) triangle inserts, the tool provides exceptional wear resistance and maintains cutting edge integrity even under demanding conditions. With a 5‑inch long shank and a robust 1/2″ diameter, the tool fits standard collet sizes and delivers consistent torque transmission. The kit includes two interchangeable inserts (TNMC-32-NV and TPMC-32‑NV), a 4‑40 flat‑head cap screw, and a dedicated wrench, allowing users to quickly change inserts without additional tooling. Designed for pitch ranges from 8 to 36 threads per inch, the tool creates 60° thread profiles that meet industry standards for accuracy and surface finish. Its compact form factor and lightweight design (8.48 oz) make it ideal for handheld operation as well as CNC spindle mounting, providing flexibility across a variety of machining environments. ![[Product front view showing all components]](https://www.ecomhomes.store/wp-content/uploads/2026/08/5398185830684bc9b5fbb1e82cc98409.jpg)
