Features and Advantages of Korloy Double Clamp Boring Bars

Korloy DOUBLE CLAMP boring bars are the first choice holder where increased tool life is required in rough boring applications. The double clamp system offers extremely high rigidity, prevents insert lift off and reduces vibration - even in the most aggressive conditions.

- Simple and powerful clamping system operated by a single clamp screw

- Through coolant

- The powerful double-clamping system (upper and internal) is suitable for machining in very tough cutting conditions: roughing, heavy roughing and heavy intermittant cutting

- The holder offers precision due to the special design in the rear of the clamp

- Compact and optimized design for avoiding chip interference with a powerful clamp
