Sandvik Coromant 5780212 Lock Pin Indexable Turning T-max P

Product Description

The SANDVIK COROMANT 5780212 is a lock pin designed to secure inserts and clamps in indexable turning toolholders. Conforming to the MN-46 industry standard, this pin features a 1/4-28 thread, a 3/32 inch hex socket drive, and an overall length of 0.65 inches. It is a critical retention component in toolholder assemblies, keeping the cutting insert firmly seated during turning operations. Licensed HVAC and metalworking trades alike recognize the importance of exact-fit fasteners, and this pin is spec-matched to work within the T-Max P series platform. The 0.25-pound unit weight reflects the compact, precision-machined form factor.

This lock pin is intended for use in indexable turning applications, specifically within the SANDVIK COROMANT T-Max P series toolholder system. It suits lathe operations in both production and job-shop environments where MN-46 clamps are in use. The pin is sold individually per package, with a minimum order quantity of 5 units, making it practical to stock as a consumable maintenance item on toolholders that see regular insert indexing cycles.

Installation Notes

Installation is performed by machinists or toolroom technicians servicing indexable turning toolholders. Before replacing the lock pin, ensure the lathe is fully powered down and the toolholder is secured in a vise or fixture to prevent movement. Use a calibrated 3/32 inch hex key to thread the pin to the manufacturer-specified engagement without over-torquing, which can damage the threaded bore. Inspect the mating clamp and toolholder bore for wear or contamination before installing a new pin.
