The Sumi-Turn X Bar eliminates vibration in ID boring operations even if tool overhang is 6 x D. The new double pocket style head increases rigidity and effective chip control significantly reducing the cost of rough boring large diameters and deep holes.

Its just like using a solid carbide bar - reliable machining and round, straight, parallel bores.
