Magnum 1/4 Inch Insert 3/8 Inch Shank Indexable Tool Holder (AR6)

Eliminate inconsistent tool geometries caused by manual grinding with this right-hand indexable tool holder. Built with a solid 3/8-inch steel shank, it resists intense bending moments while securely fastening 1/4-inch carbide inserts. The AR-style approach angle is optimized for turning up to a square shoulder, providing the structural rigidity and positive locking required for aggressive material removal in steel and cast iron.
