Sgs 30309 Square End Mill 5/64 in 2 Flute Solid Carbide

Product Description

The SGS 30309 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 5/64 inch (0.0781 inch) mill diameter with a 3/16 inch (0.1875 inch) length of cut and a 1/8 inch straight-cylindrical shank. The two-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation during cutting passes. Manufactured from micrograin solid carbide, this end mill delivers rigidity and wear resistance in demanding cutting conditions. It ships in a bright, uncoated finish and is rated for use across a broad range of workpiece material categories.

This end mill is suited for light-duty precision milling tasks including slotting, profiling, and contouring in small-bore or tight-clearance applications. The 5/64 inch diameter makes it appropriate for intricate feature work on ferrous metals, non-ferrous alloys, and high-temperature alloys. It is a single-end tool with a 1-1/2 inch overall length, making it compatible with standard CNC machining centers, manual mills, and precision die-mold work where small-diameter tooling is required.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into a collet or end mill holder, ensuring proper runout is verified before cutting. Power down and lock out the spindle before changing tooling. Consult machine manufacturer feed-and-speed guidelines for the specific workpiece material before beginning any cut.
