Sgs 31256 Square End Mill 7/32 in 4 Flute Carbide Altin

Product Description

The SGS 31256 is a solid carbide square end mill designed for precision material removal in demanding machining applications. Built to Series 16 specifications, it features a 7/32 inch (0.2188 inch) cutting diameter, a 7/16 inch (0.4375 inch) length of cut, and a stub-length profile with a 2 inch overall length. The AlTiN coating provides thermal resistance and extended tool life in high-speed cutting environments. Four flutes with a 30-degree right-hand helix and variable index geometry promote efficient chip evacuation and reduced chatter. This end mill is center-cutting and suited for slotting, profiling, and peripheral milling operations performed by machinists and tool-and-die professionals.

The SGS 31256 is rated for use across a broad range of workpiece material categories, including hardened steels, cast irons, stainless steels, non-ferrous metals, carbon and alloy steels, and high-temperature superalloys. The straight cylindrical shank with a 1/4 inch diameter fits standard collet chucks and end mill holders common in CNC machining centers and manual milling machines. The stub-length design provides added rigidity in tight-clearance setups where deflection control is critical.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• AlTiN coating for elevated thermal protection during high-speed or dry cutting
• 4-flute, variable index configuration reduces harmonic vibration
• 30-degree right-hand spiral flutes for efficient chip flow
• Center-cutting geometry allows plunge entry into the workpiece
• Stub length increases rigidity and minimizes deflection in close-tolerance work

Compatibility

Compatible with workpiece material categories H (hardened steels), K (cast irons), M (stainless steels), N (non-ferrous metals), P (carbon and alloy steels), and S (high-temperature alloys and superalloys). Fits 1/4 inch straight-bore collet chucks and end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Secure the shank fully within the collet or end mill holder to the recommended engagement depth before tightening. Verify spindle runout is within acceptable limits prior to operation, as excessive runout accelerates wear on carbide tooling. Follow machine manufacturer guidelines and applicable shop safety standards when setting speeds and feeds for the workpiece material.
