With a bore diameter of 3.1496 inches (80 mm) and a bore depth of 2.0866 inches (53 mm), this adapter provides a stable interface between the machine spindle and boring bar assemblies. The C8 connection size ensures rigid coupling and accurate tool positioning. External coolant delivery keeps cutting zones clear during deep boring operations. This adapter is installed by machinists and toolroom technicians working on CNC lathes, boring mills, and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for industrial machining environments requiring modular tooling flexibility. It is used in applications where a standardized C8 interface is specified, including heavy-duty boring operations on both horizontal and vertical machining centers. The 3.1496-inch body diameter and external coolant configuration make it appropriate for production and job shop settings where tool change time and rigidity are both priorities. Compatible lock screw part number 5758794 is specified for use with this adapter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBore diameter of 3.1496 inches (80 mm) for precise tool fit\u003c\/li\u003e\n  \u003cli\u003eBore depth of 2.0866 inches (53 mm) for secure tool engagement\u003c\/li\u003e\n  \u003cli\u003eC8 connection size for standardized modular interface\u003c\/li\u003e\n  \u003cli\u003eExternal coolant delivery to maintain cutting zone temperature control\u003c\/li\u003e\n  \u003cli\u003eLock screw size of 2.16 inches for secure clamping\u003c\/li\u003e\n  \u003cli\u003eCompatible lock screw: 5758794\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with C8 modular tooling systems.
