Shars 1/2 inch Indexable Threading Tool Holder with 5 ER16 Inserts

Description

Product Overview

The Shars 1/2 inch threading tool holder is engineered to meet the demanding requirements of modern machining environments. Constructed from high‑strength steel, the holder provides a rigid platform that maintains precise alignment of the cutting inserts during high‑speed operations. The tool holder accommodates five ER16 inserts, each inscribed with a 3/8 inch circle, allowing users to select the optimal geometry for a wide range of thread sizes. Included with the holder are a shim, shim screw, and a T15 key, ensuring quick and secure installation of the inserts. The overall length of 3‑1/4 inches and a shank size of 1/2 inch make the holder compatible with standard CNC spindle noses and manual turret machines. Designed for both industrial and scientific applications, the holder delivers repeatable thread quality while minimizing wear on the machine spindle.

Usage

This threading tool holder excels in environments where accuracy and efficiency are paramount. It is ideal for producing external and internal threads on steel, stainless steel, aluminum, and other common engineering alloys. The holder’s indexable design allows machinists to swap inserts rapidly, making it suitable for batch production, prototype development, and small‑lot manufacturing. Whether mounted on a CNC lathe, a manual turret lathe, or a multi‑spindle machining center, the holder provides stable support that reduces vibration and improves surface finish. The included T15 key and shim screw simplify the changeover process, enabling operators to maintain tight tolerances without extensive tool‑room downtime. Its compact size also facilitates use in tight workspaces, such as deep‑hole drilling or confined fixture setups.
