When you're staring down a part with deep cavities or narrow channels, long shank tools could be the difference between a finished job and a missed opportunity. Severance Tool Industries now offers custom-made versions of their standard lineup -- including Chatterless Countersinks™ and Midget Mills® -- with shank lengths reaching up to 15 inches.

The primary advantage for a versatile shop is the ability to reach deep into cavities, narrow channels, or complex engine components where standard tooling simply cannot fit. This extended reach allows machinists to perform precision deburring, internal profiling, and countersinking without the need for risky tool extensions or expensive custom fixtures.
While the added length increases the risk of vibration and deflection, these tools are engineered from high-grade materials like carbide and HSS to balance reach with necessary rigidity.
By incorporating these tools, job shops can accept more complex projects in the aerospace and automotive sectors, knowing they can maintain accuracy even in hard-to-access areas. Ultimately, long shank tools provide the machining flexibility required to handle specialized, deep-featured components efficiently and safely.
