Sgs 31469 Square End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The SGS 31469 is a double-end, square-profile solid carbide end mill designed for precision milling in a wide range of metalworking applications. It features a 1/4 inch mill diameter, a 1/2 inch length of cut, and a 2.5 inch overall length, with a 30-degree right-hand helix and four flutes ground from micrograin carbide stock. A TiN coating is applied to improve surface hardness and extend tool life in abrasive cutting conditions. Centercutting geometry allows the tool to plunge as well as profile. Licensed machinists and CNC operators typically specify this tool for close-tolerance work on milling machines and machining centers.

The 31469 is rated for use across several primary workpiece material categories, including hardened steels, cast irons, stainless steels, non-ferrous metals, long-chipping steels, and heat-resistant superalloys. The double-end design doubles the number of available cutting edges per tool, which reduces per-cut tooling cost in production environments. The stub-length classification keeps deflection low at this small diameter, making it well suited for shallow-depth, high-accuracy slot milling, profiling, and contouring operations.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiN coating extends tool life in abrasive and hard workpiece materials
• Double-end design provides two usable cutting ends per tool
• 30-degree right-hand spiral flute geometry promotes efficient chip evacuation
• Centercutting capability allows plunge entry into the workpiece
• Stub-length profile minimizes deflection at 1/4 inch diameter

Compatibility

Designed as an OEM-style replacement or standard tooling selection for 1/4 inch straight-cylindrical shank collets and tool holders used on vertical and horizontal milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Verify that the collet or tool holder bore matches the 1/4 inch shank diameter before mounting. Secure the shank to the minimum recommended insertion depth for the holder type being used, and confirm runout with a dial indicator before beginning a cut. Follow machine manufacturer guidelines and applicable shop safety procedures when changing tooling.
