Sandvik Coromant 5739764 Indexable Copy End Mill

Product Description

The SANDVIK COROMANT 5739764 is an indexable copy end mill designed for profile milling and contour operations in metal cutting applications. It accepts two R300-1340 inserts secured by screw clamping and delivers a 1.25-inch cutting diameter with a maximum depth of cut of 0.248 inches. The cylindrical shank measures 4.5 inches in length, and the overall length is 6 inches. Through-coolant capability directs fluid directly to the cutting zone, extending insert life during demanding operations. The toolholder body is steel construction and follows the RA300 toolholder style, part of the CoroMill 300 series platform. Installed by machinists and toolroom professionals working in CNC machining centers.

This end mill is suited for copy milling, ramping, and helical interpolation in ferrous and non-ferrous materials. The 6-inch overall length accommodates reach requirements common in die and mold work as well as general part profiling. The two-flute indexable design allows for quick insert indexing without removing the tool from the spindle, reducing downtime in production environments. The ISO designation for this toolholder is RA300-032O32-13H, which aids in cross-referencing within compatible tooling systems. Typical applications include roughing and semi-finishing passes on prismatic parts in both job shop and high-volume machining settings.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with indexable milling toolholders. Verify spindle bore compatibility and shank clamping torque per the machine tool manufacturer specifications before mounting. Ensure the machine is fully powered down and the spindle is locked before changing inserts or seating the tool in the holder. Follow the toolholder manufacturer guidelines for insert screw torque when indexing R300-1340 inserts.
