This adapter features a 1.5748-inch (40 mm) bore diameter with a bore depth of 1.2008 inches (30.50 mm) and a body length of 5.0354 inches (127.90 mm). The C4 connection size provides a rigid, repeatable interface for modular tooling systems. External coolant delivery directs fluid to the cutting zone for improved chip evacuation and tool life. A screw thread lock mechanism with a 5.22-inch lock screw secures the assembly. Machinists and CNC setup technicians install this adapter in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis modular adapter is suited for use in CNC lathes, turning centers, and machining centers configured with compatible C4 modular tooling interfaces. It is applied in both roughing and finishing boring operations on steel, cast iron, and similar workpiece materials where coolant control and toolholder rigidity are critical. The adapter accommodates the lock screw part number 5758505, making it a direct fit within a coordinated SANDVIK COROMANT modular system. It is appropriate for shops running production runs or precision one-off work where consistent bore sizing and repeatable tool setup are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.5748-inch (40 mm) bore diameter for precise internal boring fitment\u003c\/li\u003e\n\u003cli\u003eC4 modular connection size for rigid, repeatable tool interface\u003c\/li\u003e\n\u003cli\u003eBore depth of 1.2008 inches (30.50 mm) supports controlled engagement\u003c\/li\u003e\n\u003cli\u003eBody length of 5.0354 inches (127.90 mm) with 40 mm body diameter\u003c\/li\u003e\n\u003cli\u003eExternal coolant configuration for direct coolant delivery to the cutting zone\u003c\/li\u003e\n\u003cli\u003eCompatible lock screw part number 5758505 for secure thread lock assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SANDVIK COROMANT C4 modular tooling systems.
