Sgs 31721 Square End Mill 0.5 in 2 Flute Solid Carbide

Product Description

The SGS 31721 is a 2-flute, solid carbide square end mill designed for precision milling operations across a broad range of workpiece materials. Built from micrograin carbide, it delivers the edge retention and rigidity needed for consistent performance in demanding shop environments. The 0.5 inch cutting diameter pairs with a 0.625 inch length of cut, a 0.5 inch straight-cylindrical shank, and a 2.5 inch overall length. The 30-degree helix angle and spiral flute geometry promote efficient chip evacuation. This is a stub-length, uncoated, centercutting tool sold as a single unit.

The SGS 31721 is suited for milling ferrous and non-ferrous metals, high-temp alloys, and composite materials. Its right-hand cut and right-hand flute configuration makes it compatible with conventional vertical and horizontal CNC machining centers and manual knee mills. The centercutting design allows plunge entry, expanding its range of usable operations. Machinists and toolroom operators in production and job-shop environments will find this tool applicable across slotting, profiling, and pocket-milling applications.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• 2-flute design with 30-degree helix angle promotes chip clearance in slotting and full-width cuts
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Straight-cylindrical shank fits standard ER and set-screw toolholders
• Stub length provides added rigidity and reduced deflection in short-reach applications
• Uncoated finish compatible with a wide range of workpiece materials including steel, aluminum, cast iron, and exotic alloys

Compatibility

Designed as an OEM-style replacement and standard-fit solid carbide square end mill for CNC machining centers and manual mills accepting a 0.5 inch straight-cylindrical shank. Rated for use with workpiece material codes H, K, M, N, P, and S per the supplier material classification system.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Confirm shank runout and toolholder concentricity before cutting to avoid premature edge wear or tool failure. Use appropriate cutting fluid or coolant as dictated by the workpiece material and machine specifications. Consult the machine manufacturer and applicable shop safety standards when setting feeds, speeds, and depth of cut.
