Osg 8502070 Square End Mill 0.2756 in 2 Flute Solid Carbide

Product Description

The OSG 8502070 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. With a 0.2756-inch mill diameter and a 0.6299-inch length of cut, this tool is built for controlled material removal in tight tolerances. The 0.315-inch shank diameter seats into standard collets and tool holders. Constructed from micrograin carbide, the 8502070 delivers rigidity and wear resistance in demanding cutting conditions. The bright, uncoated finish makes it well-suited for non-ferrous metals and other materials where coating is not required. This is a right-hand cut, right-hand flute configuration with a 30-degree helix angle.

This end mill fits standard machining center and manual milling setups where a regular-length, two-flute tool is specified. The two-flute design improves chip evacuation in softer materials and provides clearance in slotting operations. The Series 8120 designation places it within a defined product family from OSG. Typical users include CNC machinists, tool-and-die technicians, and precision machining shops working in production or prototype environments.

Compatibility

Designed as an OEM-style solid carbide square end mill in the OSG Series 8120 line, compatible with standard collet and tool holder systems accepting a 0.315-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping to confirm proper tool seating. Follow shop standards and machine manufacturer guidelines for speeds, feeds, and depth-of-cut parameters appropriate to the workpiece material.
