Sandvik Coromant 5757809 Eccentric Pin Indexable Tools

Product Description

The SANDVIK COROMANT 5757809 is an eccentric pin designed for use with indexable turning and milling tool assemblies. This small-format clamping component secures cutting inserts within compatible toolholders by providing precise rotational adjustment during insert indexing. The pin features a 4mm hex socket drive and is engineered to work with a 1/2 inch inscribed circle insert geometry. At 0.47 inches in length and 0.35 inches in both height and width, it is a compact, precision-machined part that weighs approximately 0.25 pounds per package. Installation and replacement are performed by toolroom technicians and machining professionals during scheduled insert changes or toolholder maintenance.

This eccentric pin is suited for indexable milling and turning applications where consistent insert clamping force and repeatable positioning are required. It is typically found in production machining environments, job shops, and maintenance operations where Sandvik Coromant modular tooling systems are in use. The 5757809 corresponds to industry standard number 365.2-874 and is sold individually with a minimum order quantity of 5 units per transaction.
